Differences between large companies vs. SME´s and micro-companies Degree: Master of Science in Economics & Business Administration Programme: Strategic business development Supervisor: Ausrine Šilenskytė Year: 2025 Pages: 121 ABSTRACT: Strategy implementation refers to the process through which planned strategies are executed in practice (Heide et al., 2002; Weiser et al., 2020) and is regarded as the most challenging phase of strategic management (Ivancic, 2016; Zaidi et al., 2018), with studies estimating that up to 90% of strategies fail during implementation (Raps, 2004; Cater & Pucko, 2010). Although research on strategic planning is extensive, the execution phase remains underexplored (Tawse & Tabesh, 2021; de Oliveira et al., 2019). Moreover, existing studies focus primarily on large firms, offering limited insight into smaller enterprises (Kelliher & Reinl, 2009; Kearney et al., 2019). The purpose of this thesis is to examine how the practices and factors influencing strategy implementation differ between large and smaller companies. The theoretical framework examines the factors that could hinder or, conversely, facilitate the effective execution of the strategy. These include factors such as clarity and precision in strategic foundations and leadership and management capabilities, as well as other significant factors that influence the implementation process. The research focuses on two large, two medium, three small-sized companies and a micro company. Data is collected through semi-structured interviews, which allows a detailed comparison of practices and challenges related to strategy implementation between the organizations of different sizes. The findings show how factors influencing strategy implementation differ between large and smaller companies. Large firms typically rely on formal structures, clear strategic foundations, and distributed leadership. In smaller firms, implementation is more informal and dependent on individual leaders, often leading to fragmented practices. Resource allocation was considered important across all firm sizes, but only large companies had the capacity to manage it systematically. Small firms particularly struggled with limited leadership and management capabilities. Leadership structures were often underdeveloped, and responsibilities concentrated in the hands of founders. A critical issue discovered was the lack of consensus and commitment between owners, which significantly hindered implementation and, in some cases, led to critical organizational dysfunction. This study highlights significant internal variation within the SME category and shows that size alone does not determine implementation practices. The taxonomy analysis based on Šilenskytė and Smale (2021) reinforces the finding that organizational characteristics, not just size, shape strategic behaviour. The results also challenge the analytical validity of treating size-based categories such as SMEs as homogeneous, suggesting a need for more nuanced segmentation when analysing strategy implementation in different organizational contexts.

Strategy implementation refers to the process through which formulated strategies are translated into concrete actions and realized within the organization (Heide et al 2002; Weiser et al, 2020). While this may seem straightforward, simply putting the strategy to work often proves to be a challenging task (Koseoglu et al.,2009). Implementation is considered the most challenging aspect of strategic management (Zaidi et al 2018; Ivancic, 2016) and numerous studies suggest that most implementation efforts fail, with some estimates indicating that as many as 90 percent of strategies are not executed effectively (Cater and Pucko 2010; Raps, 2004). Although organizations may formulate strong and promising strategies, their ability to sustain competitive advantage often falters due to shortcomings in the implementation stage. Indeed, even seemingly straightforward improvements require the careful integration of numerous interdependent strategic activities, where failure in just a single element can undermine the entire effort (Weiser et al., 2020; Alharthy et al., 2017). Thus, the underlying issue is not necessarily with the strategy itself but with the organization's inability to effectively implement it. The failure of implementing strategy often stems from a lack of execution expertise as managers generally possess greater knowledge of strategy creation than of its actual implementation. In addition, the inability to navigate difficult organizational changes prevent effective implementation (Cater & Pucko, 2010). While there is extensive literature on strategic planning and positioning, the practical execution of strategies remains underexplored and is often treated superficially. (Tawse and Tabesh 2021; de Oliveira et al 2019; Ivančić 2013) Nevertheless, academic interest in the execution of strategy has been growing, with recent studies placing increasing emphasis on the dynamic and adaptive dimensions of strategy implementation (Weiser 7 et al., 2020; Amin, 2024). Despite the increasing scholarly interest, most research has continued to focus on large companies and SME´s, while limited attention has been given to strategizing within micro firms (Kearney et al., 2018). While SME literature is extensive, it often lacks clarity on whether it focuses primarily on medium-sized firms, which represent less than 1% of EU companies, or includes small companies, which together with micro enterprises make up about 99% of EU businesses, more equally (Table 1). There remains limited understanding of how small and micro enterprises characterized by informal flexible and resource-constrained environments implement strategy. These firms often execute strategy intuitively quickly adapting to external changes but face vulnerabilities due to limited resources and high dependence on individual leaders. (Kelliher and Reinl 2009; Kearney et al. 2019) Consequently, actionable insights into small business strategy execution remain sparse. By examining this underexplored context, the thesis provides a comprehensive view of strategy implementation in companies of various sizes, highlighting differences between large and smaller firms. It offers practical managerial implications and identifies future research avenues by revealing challenges and practices unique to resource-constrained, owner-driven environments. The thesis begins with an introduction to the research topic, questions, and structure, followed by a literature review covering strategy and strategy implementation. The methodology section outlines the case study approach, and the empirical part presents a comparative analysis of eight construction industry firms of varying sizes. The study concludes by integrating theoretical and empirical findings, discussing implications, and suggesting directions for future research. 1.1 Research gap The existing body of research on strategizing is predominantly conducted on larger and medium-sized organizations, often overlooking the practical challenges faced SME´s, 8 leaving a gap of in-depth research on how micro navigate strategic challenges and opportunities. (Kearney et al. 2019) This gap is particularly significant given that micro enterprises (SMEs) account over 94% of all businesses in the EU (see Table 1). This thesis provides an insight into how the factors influencing strategy implementation may differ between small and large companies, or whether they are fundamentally the same, shedding light on the unique challenges and opportunities organizations of different sizes, and especially smaller organizations, face when implementing strategy.

The findings offer much-needed guidance for small and micro firms, helping them implement strategies more effectively and supporting their growth while addressing a notable gap in existing literature. 1.3 Research structure and framing The research process will begin with the definition of the research focus, design, objectives, and questions. The theoretical phase of the research will continue with a comprehensive literature review. The necessary background and context of the existing research on strategy implementation and the factors effecting it will be provided. The research begins by presenting the methods, establishing a solid foundation for the study. This is followed by a examination of the process for identifying and selecting the case companies. The subsequent data collection phase employs semi-structured interviews to obtain qualitative insights into strategy implementation practices and the factors influencing these practices within the case companies. Within case descriptions aim to uncover critical factors affecting the strategy implementation process and following cross-case analysis analyses how these factors differ between large and small companies, reveals the findings of the study and offers a nuanced understanding of organizational dynamics in varying contexts. The thesis will conclude with theoretical and practical implications of the research findings, as well as suggestions for further research in this field. 10 2 THEORETICAL FRAMEWORK 2.1 Literature review Strategy has historically been understood in various ways, with definitions reflecting different theoretical perspectives. Originating from the ancient Greek term strategos, meaning to lead an army, the concept emphasizes coordination and planning to achieve objectives (Cummings, 1993, p.133). In modern business contexts, strategy defines the business model a firm uses to compete, while tactics refer to the specific actions taken within that model (Casadesus-Masanell & Ricart, 2010, p.196). Since this thesis focuses on strategy implementation, it does not explore the full range of strategy definitions found in the literature. However, the following selected examples highlight diverse conceptualizations and offer a brief overview of the theoretical foundations and schools of thought that shape academic understanding of strategy: “Competitive strategy is a combination of the ends (goals) for which the firm is striving and the means (policies) by which it is seeking to get there.” (Porter, 1980, p.xxiv) “Strategy refers to the decisions and actions made in the present to ensure future success and capitalize on emerging opportunities.” (Karlöf, 2004, p.19) Strategy can be explicit or implicit (Heide et al., 2002) and involves both planned and emergent elements (Mintzberg & Waters, 1985). The strategy process typically includes analysis, formulation, and implementation (Price & Newson, 2003, p.183), encompassing environmental assessment, change identification, execution, and monitoring (Karlöf, 2004). Strategies are generally classified into portfolio (corporate level), business (competitive), and operational (functional) types (Karlöf, 2004, p.10–13). Complementing this, the strategy-as-practice perspective emphasizes strategy as a dynamic and socially embedded process shaped by the actions and interactions of 11 individuals (Vaara & Whittington, 2012), particularly relevant in smaller firms, where strategy often emerges from the everyday practices of key actors (Kearney et al., 2019). 2.1.1 Strategy implementation Strategic planning is only the starting point, not the final outcome (Galpin, 1998, p.40). Strategy formulation is a multifaceted and dynamic phase involving iterative decision- making and coordinated actions by managers and employees (Li et al., 2010). It is shaped by internal and external factors and aims to guide the organization toward strategic objectives (de Oliveira et al., 2019; Friesl et al., 2021; Pučko & Čater, 2010). Ultimately, strategic success rests on coordinated action, adaptive leadership, and continuous refinement. Attempts to rush the process may undermine outcomes, as effective integration demands deliberate effort (Friesl et al., 2021, p.2–3; Hrebiniak, 2006, p.14). Despite thorough planning, many organizations struggle to translate strategic aspirations into concrete outcomes, revealing a persistent gap between planning and execution (Cater & Pucko, 2010, p.208; Noble, 1999b, p.19; Friesl et al., 2021). The implementation phase is often more challenging than the actual planning process, requiring continuous monitoring and adaptability (Galpin, 1998, p.38; Ivančić, 2013, p.2; Friesl et al., 2021; Okumus, 2001). Bridging this gap requires operationalizing strategies into tangible actions and aligning resources to meet performance targets (Heide et al., 2002; Ivančić, 2013; Li et al., 2010; Miller, 1997). Effective strategy implementation requires clear responsibilities, structured planning, and sustained execution. Leaders must align organizational structures with strategic goals, define key tasks, allocate resources, and ensure internal buy-in. Leadership is also crucial in addressing obstacles such as unclear responsibilities, resistance to change, and ineffective reward systems. (Miller et al., 2004; Friesl et al., 2021; Pučko & Čater, 2008). SI is a progressive, ongoing and integrated process, requiring meticulous planning and alignment across organizational levels (Heide et al., 2002, p.218) and demanding simultaneous efforts across key dimensions: translating strategy into actionable steps, 12 coordinating activities, monitoring progress while providing feedback, and enhancing employee competencies (de Oliveira et al., 2019). On the other hand, SI is not an instantaneous process but rather unfolds over time, combining deliberate actions with unanticipated developments. (Friesl et al., 2021; Hrebiniak, 2006). Successful implementation is contingent upon efficient resource allocation and resolving operational challenges while ensuring a holistic approach rather than focusing on isolated components (Raps, 2005, p.142). Despite extensive discussions and advice on the topic, the concept of strategy implementation often remains vague and undefined, lacking clear guidance on the essential components that make it a foundational element of an effective organization. (Crittenden & Crittenden, 2008, p.301) Strategy implementation (SI) is understood in various ways, depending on the perspective taken. In their study, Silenskyte & Smale (2021, p.515) present a useful taxonomy of SI in multinational corporations, categorizing conceptualizations into three distinct levels: O-level, I-level, and A-level perspectives. At the O-level, strategy implementation is viewed as a tangible and structured process, where planning precedes execution in a linear and predefined manner. The A-level perspective also follows the general logic of planning followed by implementation; however, unlike the O-level, strategy is understood as an emergent rather than a fixed phenomenon. Strategy implementation at the I-level is more embedded in everyday activities and reflects more of the “Strategy as Practise”-approach. This taxonomy offers a valuable conceptual framework for the present study and will also be applied to the cross-case analysis. 2.1.2 Strategy implementation in SME & micro firm context Strategic management in small and medium-sized enterprises (SMEs) is characterized by a unique set of challenges and opportunities that distinguish it from large corporations. Its importance is recognized, yet it is generally insufficiently integrated into the routine operations of the enterprise. Often, managers either underestimate the critical role of 13 strategic thinking in organizational success or lack the capacity to effectively implement a coherent strategic framework (Belas, 2020). In SME´s, strategic management is not always prioritized, and many owner-managers focus on short-term survival rather than long-term growth (Wolczek, 2018). Only a small share of SME companies prepares strategies with a time horizon exceeding five years, indicating a generally short-term orientation in strategic planning (Skokan et al., 2013). This characteristic of deprioritizing strategic management is also present in micro firms, where limited managerial capacity and highly centralized decision-making result in the owner-manager playing a central role across all business functions. Particularly, in micro and small enterprises, the strategic role is often held by the owner, (Wolczek, 2018). Strategy work in this context is closely intertwined with daily operations and is strongly shaped by the entrepreneur’s personal experiences, tacit knowledge and intuitive judgment (Kelliher & Reinl, 2009). The personal involvement of the owner or manager in the strategic process ensures fast and direct decision-making, but it can also create bottlenecks if the owner lacks strategic management expertise or if authority is overly centralized (Kearney et al., 2019). In addition, this characteristic of small and micro companies limits delegation and collaboration. (Wolczek, 2018). While flexibility in smaller organizations provides certain advantages, there are significant challenges associated with strategic implementation in small and micro firms. One of the most pressing issues is resource constraints. Many small businesses suffer from “resource poverty,” lacking sufficient financial capital and skilled personnel to pursue long-term strategic objectives effectively (Kelliher & Reinl, 2009). Consequently, owner-managers tend to prioritize immediate operational concerns over sustained strategic development (Wolczek, 2018). Strategic efforts may be postponed or abandoned entirely when urgent operational matters arise, particularly in resource- intensive contexts (Skokan et al., 2013). 14 Another critical challenge related to the high degree of owner dependence is that the firm’s strategic success often relies heavily on a single individual, making the business particularly vulnerable to disruptions such as leadership changes or burnout. (Kearney et al., 2019). Furthermore, micro and small enterprises frequently operate in intensely competitive markets where larger firms benefit from economies of scale and stronger financial resources. This competitive imbalance can hinder smaller firms’ ability to sustain long-term strategic initiatives, as they lack both the market influence and structural capacity to compete on equal terms. (Kearney et al., 2019). 2.1.3 Research on factors affecting strategy implementation The following section focuses on examining the factors contributing to strategy implementation. Building upon existing academic research, this work establishes a framework for further examination of practical implications of the factors within organizational contexts. A literature review of 13 key research articles was conducted to identify common barriers and enablers of strategy implementation. The most critical factors were selected and examined in depth, with additional studies included to support a comprehensive analysis. Beer and Eisenstat (2000) identify six key "Silent killers" of strategy execution, while Galpin (1998) highlights the "Seven Deadly Sins" that can undermine organizational initiatives. Hrebiniak (2006) in his study, conducted a survey to pinpoint major barriers to effective execution. Aziza et al. (2008) reference a study which examines the common pitfalls in SI. Building on earlier research, Heide et al. (2002) highlight seven crucial factors that affect SI outcomes, whereas Li et al. (2010) identify nine recurring factors from a comprehensive review of the literature. Crittenden and Crittenden (2008) offer an implementation toolkit to bridge the gap between strategy formulation and execution. Cater and Pucko (2010) contribute through their extensive literature review on the factors of effective SI. Aaltonen and Ikävalko (2002) focus on challenges faced by 15 organizations during implementation, while Noble (1999) introduces five key levers for enhancing cross-functional execution. Zeps and Ribickis (2015) explore the impact of variables in strategy creation on implementation success in Latvian organizations. Koseoglu et al. (2009) emphasize organizational issues as a primary cause of failure during implementation. Finally, Amin (2024) reviews internal and external factors critical to strategy execution in the public sector, further enriching the understanding of what drives successful implementation. The studies discussed above effectively summarize the key factors that either hinder or facilitate strategy implementation, and similar themes are found in several other studies and literature reviews, also incorporated to the review. According to the chosen studies, the factors in question are largely the same; however, depending on whether they materialize or not, they function either as barriers or enablers of effective strategy implementation. Based on the referenced studies, eight key factors recurring in at least four sources were selected for further examination due to their significant impact on strategy implementation (Table 2). In addition, other important factors outside the framework were included in the analysis based on their frequent occurrence in the literature, and particularly in smaller companies examined in this study. All the above- mentioned factors are summarized in table 8 (p. 88), which presents the key findings from the case company interviews regarding strategy implementation (SI) factors. 16 Table 2. Identified key factors influencing strategy implementation from literature. Factor Biggest challenges in strategy implementation (according to study) Clarity and precision in strategic foundations (Aaltonen & Ikävalko, 2002; Aziza et al., 2008; Beer & Eisenstat, 2000; Cater & Pucko, 2010; Hrebiniak, 2006; Li et al., 2010; Noble, 1999b; Zeps & Ribickis, 2005) Leadership and management capabilities (Aaltonen & Ikävalko, 2002; Beer & Eisenstat, 2000; Cater & Pucko, 2010; Crittenden & Crittenden, 2008; Galpin, 1998; Heide et al., 2002; Hrebiniak, 2006; Noble, 1999b; Li et al., 2010; Zeps & Ribickis, 2005) Communication and information flow (Aaltonen & Ikävalko, 2002; Amin, 2024; Beer & Eisenstat, 2000; Cater & Pucko, 2010; Galpin, 1998; Heide et al., 2002; Hrebiniak, 2006; Koseoglu et al., 2009; Li et al., 2010; Noble, 1999b) Resource Allocation (Aziza et al., 2008; Crittenden & Crittenden, 2008; Galpin, 1998; Heide et al., 2002; Noble, 1999b) Strategy awareness (Aaltonen & Ikävalko, 2002; Aziza, 2008; Heide et al., 2002; Zeps & Ribickis, 2005) Guidelines for implementation (Cater & Pucko, 2010; Hrebiniak, 2006; Li et al., 2010; Zeps & Ribickis, 2005) Reward systems and strategy implementation (Aaltonen & Ikävalko, 2002; Allio, 2005; Cater & Pucko, 2010; Crittenden & Crittenden, 2008; Hambrick & Cannella, 1989; Hrebiniak, 2006; Noble, 1999a; Li et al., 2010; Tawse & Tabesh, 2021; Zeps & Ribickis, 2015) Corporate culture and strategic goals (Amin, 2024; Cater & Pucko, 2010; Crittenden & Crittenden, 2008; Heide et al., 2002; Koseoglu et al., 2009) 2.2 The key factors affecting SI identified from the literature 2.2.1 Clarity and precision in strategic foundations According to Cater & Pucko (2010) and Hrebiniak (2006), a poorly conducted strategic analysis and an inadequately defined strategy are often the root causes of problems in both formulation and implementation. A lack of clarity and precision in a strategy, common across many organizations, create uncertainty within the organization and leaves employees uncertain about their role and how to contribute through their daily actions hampering its members' ability to execute the strategy in a focused and collective manner (MacLennan & Markides, 2021). According to research conducted by Skokan et 17 al. (2013), businesses that have formulated a detailed strategy tend to achieve, on average, significantly better performance outcomes. Without clearly defined strategic goals and short-term, measurable objectives for organizational units, it becomes difficult to maintain focus on key challenges, leading to ineffective execution (Aaltonen & Ikävalko, 2002; Allio, 2005; Hrebiniak, 2006; Ivancic, 2013; Noble, 1999b; Rumelt, 2011). In addition, according to Li et al. (2010), drawing on Heracleous (2000), managers must feel confident in the strategy and see its value. If managers see the strategy as flawed or threatening, they may resist it. (Li et al., 2010). Koseoglu et al. (2009) state that the formulation process plays a more crucial role in explaining strategic failures. Conversely, Cater and Pucko (2008, p.230) argue that “It is better to have a less perfectly crafted strategy which is fully executed than to formulate an excellent strategy which is never implemented”. Lee and Puranam (2016, p.1529) further explain that even well-executed strategies, like cost-cutting, may fail if they do not align with industry dynamics, highlighting the importance of strategic fit alongside execution. 2.2.2 Leadership and management capabilities Leaders play a crucial role in the implementation of strategy (Šilenskytė, 2020; Noble, 1999a; Crittenden & Crittenden, 2008; Noble, 1999a) and effective leadership is essential for identifying areas where change is necessary and overcoming obstacles that may arise during the implementation process. Leaders are also responsible for managing people, motivating them, and adjusting organizational structures to drive successful change. (Cater & Pucko, 2010) Noble (1999a) and Beer & Eisenstat (2000) emphasize the role of middle managers acting as powerful agents in driving strategic success, as effective strategy execution increasingly depends on lower-level managers who can guide teams to align and execute critical strategic initiatives across various functions. Managers’ cognitive ability to 18 anticipate and adjust their actions is vital for effective strategy implementation, helping them overcome challenges like cultural barriers and respond to feedback to keep the organization on track (Tawse & Tabesh, 2021). Effective management of personnel is a cornerstone of both strategy creation and execution, as employees’ ambitions, emotions, and needs have a profound influence on organizational outcomes. Neglecting these human factors can result in significant opposition to strategic initiatives (Heide et al., 2002). To address this, leaders play a pivotal role in identifying critical areas requiring transformation and proactively addressing resistance. Their responsibilities include managing key individuals, aligning incentives, and adjusting organizational structures to facilitate the successful implementation of strategic goals (Cater & Pucko, 2010). 2.2.3 Communication and information flow In numerous studies and articles on strategy implementation, communication has consistently been highlighted as the most crucial factor for success (Aaltonen & Ikävalko, 2002; Li et al., 2010, p.19; Galpin, 1998; Beer & Eisenstat, 2000). When companies clearly communicate their winning approach, aligning execution with corporate goals, they foster a culture of performance (Aziza et al, 2008). Written strategies play a significant role in successful strategy implementation. A well- documented strategy provides clear guidance and direction, ensuring alignment and coherence across all levels of the organization (Zeps & Ribickis, 2015). Additionally, structured tools such as templates and frameworks help present the strategy consistently, facilitating understanding and the effective explanation of strategic objectives (Allio, 2005, p.18; Noble, 1999b). Providing context helps employees understand the rationale behind the new direction and how their roles contribute to the organization’s strategic goals (Li et al., 2010) They help employees to comprehend how the strategy is implemented in day-to-day operations and furthermore, to become proactive agents of change within the organization. (Aziba et al., 2008). 19 A hierarchical management style can significantly obstruct open communication from lower levels and hinder an organization’s ability to learn and adapt (Beer & Eisenstat, 2000). In contrast, frequent vertical communication the organization promotes strategic consensus by fostering shared attitudes and values (Li et al., 2010). When organizational members do not have access to consistent information or when communication must traverse multiple hierarchical layers, the resulting divergence in understanding can hinder the development of strategic consensus (Rapert et al., 2002). In addition, open, interactive communication, as well as active listening, fosters a shared understanding and strengthens commitment to the strategy’s success enhancing the decision-making process and organizational flexibility (Šilenskytė, 2020; Beer & Eisenstat, 2000). 2.2.4 Resource allocation To implement a successful strategy, organizations must ensure they have sufficient re- sources allocated to meet their strategic goals. Insufficient allocation of resources can significantly hinder the execution of an organization's strategy and slow its progress (Amin, 2024; Cater & Pucko, 2010; Crittenden & Crittenden, 2008; Galpin, 1998; Heide et al., 2002; Li et al., 2008; Kohtamäki et al., 2012). It is crucial for organizations to carefully assess their resource needs and ensure that they are adequately prepared to achieve their strategic objectives (Cater & Pucko, 2010). Crittenden and Crittenden (2008, p.301) highlight that proper resource allocation involves utilizing essential resources such as finances, people, and capabilities. However, resources should not only be viewed in financial terms (Crittenden & Crittenden, 2008; Heide et al., 2002, Amin, 2024). Physical capital, such as facilities, equipment, and technology, as well as human capital, which encompasses expertise, experience, and motivation as well as organizational capital, including processes, systems, and networks, also plays a key role in supporting strategic goals. (Crittenden and Crittenden, 2008) 20 2.2.5 Strategy awareness Aaltonen and Ikävalko (2002) note that high volumes of communication do not guarantee understanding. Their study highlights the need for clear, effective communication that ensures comprehension at all organizational levels. Typically, 95% of the workforce does not understand the strategy (Kaplan and Norton, 2005), thus, simply sharing information is not enough; employees must understand, accept, and internalize the strategy for effective implementation (Aaltonen & Ikävalko, 2002). If employees do not understand the company's strategy, the likelihood of successful implementation diminishes, which can negatively impact financial performance (Crittenden & Crittenden, 2008; Aziza et al., 2008). When communication occurs frequently across different levels of the organization (for example, between management and employees), it fosters a shared understanding of strategic priorities. This, in turn, enhances organizational performance, as everyone has a clear understanding of the goals to be achieved and the reasons behind their importance. (Li et al., 2010) Although strategy may be clear at the top levels of the organization, its understanding and adoption across the entire workforce is often lacking (Allio, 2005; MacLennan & Markides, 2021) and managers often lead implementation teams despite having a limited understanding of the overarching strategy (Noble 1999b). 2.2.6 Guidelines for implementation For a strategy to be effectively implemented, employees must recognize its existence and possess the requisite knowledge and skills to carry it out (Heide et al., 2002). MacLennan and Markides (2021), in their survey of over 2,000 managers, found that while managers generally possess a clear understanding of their organizations' overarching goals, they exhibit considerably less clarity regarding the specific methods and processes employed to achieve these objectives 21 Many processes and programs are launched without a clear understanding of their purpose or the specific objectives they aim to achieve. This lack of strategic direction hampers effective change, as actions are taken without a coherent plan or vision (MacLennan & Markides, 2001). Comprehensive and well-structured guidelines ensure employees can effectively contribute to the organization's success. Without clear frameworks or explicit instructions, employees struggle to align their daily efforts with strategic objectives, leaving the organization vulnerable to inefficiency and misaligned actions (Allio, 2005, p.19; Beer & Eisenstat, 2000; Hrebiniak, 2006) 2.2.7 Reward systems One of the most frequently emphasized aspects in studies and articles on strategy implementation is the importance of aligning reward systems with strategic objectives (Aaltonen & Ikävalko, 2002; Allio, 2005; Al-Ghamdi, 1998; Cater & Puco, 2010; Crittenden & Crittenden, 2008; Hambrick & Cannella; 1989; Hrebiniak, 2006; Noble, 1999b; Li et al.,2010; Tawse & Tabesh, 2021; Zeps & Ribickis, 2015) However, according to Aziza et al. (2008), 70% of organizations do not link middle management incentives to strategy. Incentive systems must be consistently aligned with the organization's strategic objectives. (Noble, 1999b; Hambrick & Cannella, 1989, p.282) When incentives conflict with these goals, it can significantly hinder effective strategy SI. For instance, if employees are rewarded solely based on the performance of their specific functions, they may lack the motivation to contribute toward overarching, shared objectives (Noble, 1999b, p.27; Hrebiniak, 2006, p.23). Motivating individuals in strategy implementation requires a balanced mix of financial and non-financial incentives, such as recognition and growth opportunities. Incentive systems should be flexible and tailored to individual goals to maintain commitment throughout the implementation process (Crittenden & Crittenden; 2008, p.307; Silenskyte, 2020; Noble, 1999b). Rewards can take many forms: they may be formal, such as bonuses, promotions, or commissions, or informal, such as verbal praise, recognition, 22 or a sense of pride and accomplishment. Tailoring the type and criteria of rewards to fit the specific strategic direction of the business is essential. Hambrick & Cannella (1989) 2.2.8 Corporate culture and strategic goals Organizational culture is seen as one of the most critical factors influencing the success of strategy implementation, drawing on insights from multiple studies (Aaltonen & Ikävalko, 2002, p.417; Amin, 2024, p.68; Heide et al., 2002, p.219; Hrebiniak, 2006, p.16; Koseo-glu et al., 2009) It encompasses the collective cognitive frameworks and behavioural patterns within an organization, shaped by shared values, attitudes, and norms that influence how individuals are likely to act (Cater & Pucko, 2010, p.307; Heide et al., 2002, p.219). Organizational culture problems often stem from a lack of trust, which can manifest as employees' reluctance to share knowledge with their colleagues. Another cultural challenge is a tendency to focus on short-term objectives rather than long-term goals (Cater & Pucko, 2010). Resistance to change often stems from perceived misalignment between new strategies and established organizational culture. Aligning strategic initiatives with core cultural values is essential to gain acceptance and support effective implementation. (Merkus et al., 2019) Change, being closely related to SI, is often perceived as synonymous with cultural transformation, highlighting the profound interplay between strategic shifts and the deeply ingrained values, norms, and behaviours within an organization. To further complicate matters, different units and functions within organizations often develop distinct subcultures, making it challenging to maintain strategic coherence. (Hrebiniak, 2006) 23 2.2.9 Other significant factors outside the framework The following section briefly examines other commonly highlighted factors that were mentioned two to three times across the selected sources and were identified in the case companies as influencing factors in strategy implementation, following the abductive research approach (Eriksson & Kovalainen, 2016, p.24; Saunders, 2023, p.154– 161). 2.2.9.1 Challenges regarding organizational structure and decentralization Effective strategy implementation, at any level, depends on the active participation and collaboration of all employees (Aziza et al., 2008, p.16; Crittenden & Crittenden, 2008, p.304, Noble, 1999b, p.121; Tawse & Tabesh, 2021, p.30) Regular communication can strengthen cross-functional relationships by fostering a deeper understanding and greater appreciation of each department's contributions (Noble, 1999a). Integrating distinct organizational units to reach overarching goals is crucial for successful strategy execution, despite its challenges (Hrebiniak, 2006, p.23). 2.2.9.2 Consensus and commitment Strategic consensus refers to the degree to which members within an organization align their perceptions and agree on the key strategic priorities. It reflects the level of shared understanding regarding the organization's direction and objectives. (Rapert & Garretson, 2002) In addition, that the lack of consensus is an obstacle to the creation of a sound strategy (Koseoglu, 2009), numerous studies highlight that both external and internal consensus are crucial for the successful SI (Li et al., 2010). Gaining commitment from all levels of an organization can be a significant obstacle (Noble, 1999a, p.121). A lack of both collective clarity and commitment often leads to fragile agreement on strategic objectives. Strengthening both understanding and dedication among stakeholders is essential to bridging the critical "implementation gap" and ensuring the success of strategic initiatives (Li et al., 2010, p.22). 24 2.2.9.3 Employee engagement To enhance organizational performance, it is essential to engage employees in participative strategic planning (Kohtamäki et al., 2010; Zeps & Ribickis, 2015). This approach improves their comprehension of the company's strategy and fosters a greater commitment to its implementation (Kohtamäki et al., 2012). Engaging both senior and junior staff in the initial stages of strategy development allows them to foster a sense of ownership across the organization even before the implementation process starts (Noble, 1999b). However, companies often fail to fully leverage the expertise and insights of lower-level employees. Not involving employees adequately can result in missed opportunities for valuable contributions to the strategic process (Beer & Eisenstat, 2000). 2.2.9.4 Working against power structure Challenges in strategy implementation can arise from the attitudes or perceived threats from operational managers towards upper management. Furthermore, if team cohesion within organizational subgroups is particularly strong. If cliques form, it can lead to the polarization of these groups, creating divisions that hinder collaboration. The distribution of power within an organization plays a critical role, as it shapes decisions on allocating the resources required for strategy execution (Noble, 1999a). As Hrebiniak (2006) points out, working against the existing power structure can obstruct progress unless coalitions are formed, and influential stakeholders are engaged. Similarly, Cater and Pucko (2010) emphasize that the dynamics of organizational power significantly impact the successful realization of strategic initiatives. (Cater & Pucko, 2010; Noble, 1999a) 2.2.9.5 External distractions and operational pressures Conflicting priorities and an overload of competing activities often diverted attention away from successful implementation (Al-Ghamdi, 1998). Managers often lose focus, enthusiasm, and direction when transitioning from strategic workshops back to daily 25 operations, as the practical challenges of implementing broad strategies like "improving internal efficiencies" become unclear amidst competing demands, limited resources, and re-emerging priorities (Allio, 2005, p.1). 2.2.9.6 Cross-unit collaboration and coordination Effective strategy implementation requires strong coordination across different units within an organization, as these units often have differing goals and perspectives. Aligning objectives across functions, rather than focusing on individual departmental goals, can reduce conflict and improve performance. Additionally, as strategies grow more complex, the role of lower-level managers becomes critical in ensuring cross- functional coordination and alignment, facilitating successful execution. (Beer & Eisenstat, 2000; Hrebiniak, 2006; Noble, 1999b) Major large enterprises struggle with siloed departments and structures, requiring formal coordination mechanisms. Silos often emerge in organizations with competitive cultures, fragmented goals, and reward systems that prioritize individual or unit performance. Leaders may foster isolated domains, reinforcing division through power dynamics and hierarchical control. (de Waal et al., 2019) 2.3 Synthesis SI is a critical phase that transforms plans into tangible outcomes. Without effective implementation, a strategy may remain purely theoretical and fail to yield the expected benefits. Many organizations struggle with execution challenges, and research indicates that up to 90% of strategies do not materialize as intended. Successful SI relies on several key factors. A clear strategic foundation is essential, as ambiguous and unmeasurable objectives result in fragmented execution. The role of leadership is particularly pronounced in driving change and motivating personnel. 26 Through communication, the strategy is embedded within various organizational levels, ensuring that strategic objectives become an integral part of daily operations. Communication is central to execution, serving as the binding element between different organizational layers and ensuring that all stakeholders comprehend the significance of the strategy and their respective roles in its realization. The allocation of resources to strategically appropriate areas support implementation and ensures that the organization’s capabilities align with its long-term goals. Furthermore, the compatibility of organizational culture with the strategy facilitates the successful execution of necessary changes, ensuring alignment with the company’s values and operational models. Separating strategic planning from implementation can lead to failure; thus, execution must be integrated into the planning phase to avoid fragmentation. The challenges of strategy implementation are fundamentally similar across organizations of different sizes, but their manifestations vary significantly. Large enterprises benefit from established processes and resources, yet their complex structures and hierarchies can slow execution. Smaller firms, on the other hand, can adapt strategic changes more swiftly but often face resource constraints and difficulties in embedding strategic thinking into daily operations. The role of communication is particularly pronounced in addressing these differences. In large organizations, communication acts as a structural adhesive, integrating different levels of the organization into strategic objectives while ensuring that all stakeholders receive uniform and timely information. In smaller firms, communication enhances flexibility and facilitates the rapid adaptation of strategy into daily operations, where close collaboration and informal communication play a significant role. Strategic planning and execution require different approaches depending on the size and operational environment of a company, but the fundamental success factor remains effective and clear communication. 27 3 METHODOLOGY The following chapter presents the methodological approach adopted in the study, outlining the a) underlying philosophical assumptions, b) the selected research approach, c) methodological choices, d) research strategy. As described by Saunders (2023, p. 130), the themes (a-d) serve as a framework for structuring these key themes, guiding the development of the research logic and structure. This chapter further describes the case selection, data collection process, and analytical techniques used to ensure a rigorous investigation. Finally, the chapter concludes with a discussion on the validity and reliability of the study, reinforcing the credibility of the research findings. 3.1 Research philosophy Researchers must practice reflexivity by critically examining their own beliefs, assumptions, and biases to ensure alignment between philosophical stance and research design. This reflection supports methodological consistency, enhances credibility, and involves actively questioning one’s worldview to connect philosophical assumptions with research practice (Saunders, 2023, p. 131). To support this, research philosophy provides the foundational framework for how research is approached and conducted, built on ontology, epistemology, and axiology (Saunders, 2023, p. 161; Eriksson & Kovalainen, 2016, p. 14). Ontology concerns what is real, epistemology what constitutes valid knowledge, and axiology how researchers’ values influence choices (Saunders, 2023, p. 133–134; Eriksson & Kovalainen, 2016, p. 15–16). Research philosophies can be distinguished based on where their underlying assumptions lie along the spectrum between objectivism and subjectivism (Saunders, 2023, p.162). Objectivism assumes that social phenomena exist independently of perception, aiming to uncover one truth through observable facts, with minimal researcher influence (Saunders, 2023, p. 131–139). Subjectivism, in contrast, sees reality 28 as constructed through human interpretation and language. Nominalism denies an objective reality beyond interpretation, while social constructionism views reality as co- created through interaction, shaped by context (Eriksson & Kovalainen, 2016, p. 15). Subjectivist researchers accept that their values influence the research and critically reflect on their position (Saunders, 2023, p. 135–137; Dubois & Gibbert, 2010). This study adopts a social constructivist ontology, acknowledging that strategy implementation may differ by company size but does not assume it does. The approach is subjectivist, incorporating multiple narratives that shape social realities through interaction (Eisenhardt, 2021; Saunders, 2023, p. 137). While the author aims for neutrality, she recognizes the influence of personal values on topic selection and accepts the challenge of full objectivity, thus adopting an axiologically flexible stance (Saunders, 2023, p. 137). Saunders (2023, p. 145–154) identifies five main philosophical approaches in business and management research: positivism, critical realism, interpretivism, postmodernism, and pragmatism. This thesis adopts a flexible social constructivist approach, viewing strategy implementation as context-dependent and shaped through language and social interaction. It draws on interpretivism to explore perceptions and meanings, while also incorporating elements of pragmatism, recognizing that no single perspective or method can fully capture the complexity of the phenomenon (Saunders, 2023, p. 147, 153). 3.2 Research approach Theory development in research typically follows deductive, inductive, or abductive reasoning (Saunders, 2023, p. 162). Deduction starts from existing theory and tests hypotheses through structured, measurable designs aimed at generalization (Eriksson & Kovalainen, 2016, p. 23; Saunders, 2023, p. 154–161). Induction, in contrast, derives theory from empirical observations without predefined assumptions, often focusing on context and aligning with interpretivism (Eriksson & Kovalainen, 2016, p. 24; Saunders, 29 2023, p. 154–161). Abduction combines both, moving between theory and data to generate explanations, reflecting the iterative nature of empirical research (Dubois & Gibbert; Eriksson & Kovalainen, 2016, p.24; Saunders, 2023, p. 154–161). This study follows an abductive approach, beginning with a theory-based research question and moving between literature and empirical data to explore SI in smaller companies, a less-studied context. This approach allows the re-searcher to identify patterns in data and extend or refine existing frameworks (Saunders, 2023, p. 154–157). This approach also aligns with the interpretivist paradigm, as noted by Eriksson & Kovalainen (2016, p. 24). 3.3 Methodological choices Since the study does not involve quantitative data, calculations, measurements, statis- tical analysis or any other form of numerical data (Gilham, 2000, Saunders, 2023, p. 181), the methodological choice is qualitative, where “meanings are derived from words and images, not numbers”. However, if both approaches would be used in the study, it would be referred to as a mixed-method research design. (Saunders, 2023, p. 181). Although the study includes a numerical table (Table 8), the underlying data is entirely qualitative and based on the author's interpretation of the case company interviews. Qualitative methods within the interpretivist approach focus on understanding the meanings behind actions and experiences, viewing individuals as active participants in constructing their realities (Saunders, 2023, p. 184; Gilham, 2000; Ronkainen et al., 2011, p. 82) and the researcher’s role is to interpret these experiences from multiple perspectives to build theories or generate hypotheses (Bazen et al., 2021). In both qualitative and quantitative research, it is possible to use either a mono-method or a multi-method approach. This refers to whether the study relies on a single data collection method or multiple methods within the chosen research strategy. In qualitative research, there is a wide range of data collection tools, and one of the most 30 common methods is interviews (Bazen et al., 2021). In this study both primary data and secondary data is utilized, thus study applies a multi-method qualitative approach. 3.4 Research strategy The main types of qualitative research are Grounded theory, Phenomenology, Ethnography, and Case Study (Bazen et al., 2021). Although the terminology is used variably in research, this study’s methodology section is based on the research onion by Saunders (2023, p. 130), according to which these types are connected to the choice of research strategy. Grounded theory seeks to develop new theories by examining social interactions and processes. Phenomenology explores how individuals experience and interpret a phenomenon. Ethnography investigates the cultural meanings and beliefs of a group, typically through extended observation. Case Study, on the other hand, provides an in- depth description of a single person, group, or event, analysing its context and unique characteristics. (Bazen et al., 2021) Since in this study, the aim is at gaining an in-depth understanding of the interactions and phenomena (factors relating to SI) occurring within a specific context (case companies) (Eisenhardt, 1989; Halinen & Törnroos, 2005; Dubois & Gadde, 2002), a case study research strategy has been chosen for this study. The primary aim of a case study is to answer specific research questions by collecting and analysing different types of evidence available within the case setting. A case study can focus on a variety of units, or larger entities like institutions or communities, serving various purposes. Some offer rich descriptions of events, allowing readers to draw their own conclusions and others are used to partially support theories or frameworks, functioning in a quasi-deductive theory-testing manner. This study adopts the latter mentioned, which combines deductive reasoning by testing existing theoretical propositions with inductive flexibility, allowing empirical insights to refine or challenge 31 those assumptions based on the data collected. (Gilham, 2000; Dubois & Gadde, 2002; Yin, 2018, p. 15-16) Depending on the objective of the research, the researcher must select the most ap- propriate approach for the case study strategy. According to Massis and Kotlar (2014), case study approaches can be categorized into three types: exploratory, which aims to answer the question how; explanatory, which focuses on explaining why something happens; and descriptive, which seeks to describe and confirm the existence of a phenomenon in a real-life context. However, according to Yin (2018, p. 286–287), the explanatory approach aims to answer both how and why questions, whereas the purpose of an exploratory case study is to investigate and clarify research questions that will be used in future studies. Since this study’s research question begins with how and aims to uncover causal links, it is classified as explanatory. In addition to the aspects outlined above, the researcher must also determine whether to adopt a single case study or a multiple case study design. If the study includes more than one case, it follows a multiple case design (Yin, 2018, p. 54). The choice between a single case study and a multiple case study is contingent on balancing analytical depth with broader applicability. While a single case study enables a comprehensive, context- specific investigation, a multiple case study enhances comparability and generalizability (Dubois & Gadde, 2002). While unique or extreme cases may justify a single case study, a multiple case study is more suitable for exploring common patterns across several cases within the same topic (Yin, 2018, p. 54-55). As this thesis compares how strategy implementation factors appear in large and small companies, a multiple case study is the most suitable design for exploring both similarities and differences across cases. By examining multiple cases, this study aims to identify recurring themes and patterns of similarity to enable a more comprehensive and nuanced understanding of the factors that shape successful strategy implementation, thereby enhancing the broader generalizability of the findings. (Dubois & Gadde, 2002;) 32 While studies that simply reproduce previous findings offer only a limited contribution to academic discourse, those that expand theoretical frameworks drive meaningful advancements in research (Eisenhardt, 1989). Theoretical replication enables scholars to refine the boundaries of existing theories by investigating cases that challenge fundamental assumptions (Riedl, 2007) and thus extend the theory (Eisenhardt, 1989). Since the manifestation of strategy implementation factors in small firms remains underexplored, this study aims to expand the literature and deepen under-standing in that context. Identifying significant differences could enhance the relevance and applicability of existing theories. 3.5 Case selection The cases were purposively selected through the author's professional network, combining large corporations for literal replication and smaller firms for theoretical replication based on contrasting characteristics. The selection aimed to represent a sample well suited to the research objectives. The study is framed within the context of the construction sector, specifically targeting a diverse range of companies of different size. Definition of sizes are presented in detail below (table 3). Most interviewees have decades of experience working in the leadership teams of construction companies, making them familiar with the concept of strategy implementation. 33 Table 3. Company size definition (Adapted from European Comission, n.d.) Company category Staff headcount Turnover (M €) OR Balance sheet total (M €) Large Over 250 Over 50 43+ Medium-sized 50-250 10,1-50 10,1-50 Small 10-49 2,1-10 2,1-10 Micro 0-9 0-2 0-2 TOT 100 100 100 In total, eight companies were selected for in-depth analysis through semi-structured interviews for the empirical part of the research. These interviews were used to explore in greater detail the challenges and success factors associated with strategy implementation within the selected firms. The interviewees were chosen specifically targeting individuals who hold the roles of founders and/or CEOs within their respective companies and due to their experience in both the formulation and implementation of strategies, providing them with in-depth insights into the research topic. The table (table 4) presented below categorizes the case companies in the study based on their size. Where applicable, prior experience in other organizations [as a founder or CEO] is indicated in parentheses in the table. Additionally, if there are no parentheses, the interviewee has witnessed the company’s growth phases from within the case organization. 34 Table 4.

Primary data refers to information collected and analysed directly by the researcher, whereas secondary data consists of previously gathered information that is reanalysed by someone other than the original collector (Church, 2002). Interviews provide a focused, in-depth, and highly effective method for gathering comprehensive empirical data (De Massis & Kotlar, 2014), thus interviews are the main source of data utilized in this study. In addition, primary data from earlier interviews conducted by the author as preparatory material for panel discussions will be utilized for Cases Alpha, Beta, Gamma, Delta, and Epsilon (Table 5). These interviews provide background information on the case companies and valuable insights into the interviewees’ companies, including their histories and founding processes. By leveraging 35 these two complementary sources of primary data, the study aims to construct a deeper understanding of the companies, and their representatives studied. Table 5. Panel discussion participants and interviewees and coding Interviewee Interview lenght Interview conducted on Interview coding Interviewee Alpha 60 min 10/2023 P1 Interviewee Beta 60 min 10/2024 P2 Interviewee Gamma 60 min 10/2024 P3 Interviewee Delta 60 min 10/2024 P4 Interviewee Epsilon 60 min 10/2023 P5 A semi-structured interview approach is conducted for this study. This method is characterized by consistent questions across all interviews, allowing respondents to express their answers in their own words. Specific themes and topics are uniformly ad- dressed with each participant (Hirsjärvi & Hurme, 2008, pp. 47–48; Metsämuuronen, 2008, p. 40). The semi-structured format is recognized as being more effective in revealing the underlying reasons behind participants' actions compared to structured interviews (Metsämuuronen, 2008, p. 40). Thematic interviewing is an especially appropriate method for this research as it emphasizes capturing the interviewees' interpretations of the topics, ensuring that their perspectives and lived experiences are integral to the analysis. These interpretations and meanings emerge through interpersonal interaction between the interviewer and interviewee (Hirsjärvi & Hurme, 2008, p.48). In thematic interviews, the questions are not fixed in form or order; however, it is essential that the same themes are covered with all interviewees (Eskola & Suoranta 2018, 64). As a source of primary data, informal interviews conducted with employees of the case companies provide valuable background information and potentially reinforce diverse internal perspectives. These interviews provide qualitative data, offering nuanced perspectives that might not emerge in more formal questioning. From these conversations, general foundational elements related to strategy implementation within the companies will be identified and integrated into the analysis to enrich the overall 36 understanding. The aim of the semi-structured interviews is to identify the factors that influenced the SI process and integrate findings into a framework (table 8, p.88). Interviews are deemed the most effective method for data collection in this research, as certain essential information can only be obtained through direct conversations with the companies' representatives. Secondary data, which consists of previously gathered information that is reanalysed by someone other than the original collector (Church, 2002). Secondary data used in this thesis will be collected from the case companies' strategy documents, if available, and general information from the companies’ official websites, and additionally from newspaper and magazine publications. Interview questions are provided in Appendix 1. To facilitate more in-depth responses, most of the questions are open-ended, with additional follow-up questions prepared. The interview includes both introductory and content-specific questions. The interviewees have been compiled in the following table (table 6), providing an overview of the participants and relevant details for the study. Table 6. Details of the interviews.

The interview questions are organized into various categories, each with an explanation of its purpose (Table 7). To ensure that the respondents can fully comprehend the questions, they will 37 be provided with interview questions several days prior to the interview to ensure that the participants are well-prepared and familiar with the questions prior to the interviews.

Other factors affecting strategy implementation 18 To examine additional factors that might influence strategy implementation, followed by follow-up questions to gather deeper insights. In this case study, the anonymity of the interviewees has been preserved to protect both the participants and company-specific confidential information, as the content is somewhat controversial. This approach safeguards both the cases and the individuals involved (Yin, 2018, p.239). 3.7 Data anaysis In a multiple case study, each case is first analysed separately, and afterward, insights and overall interpretations are derived from these separate studies. (Yin, 2018, p.54) The researcher must observe and draw conclusions about whether meaningful patterns emerge in the data and seek out promising concepts and recurring themes. (Yin, 2018, p.166-167). Within-case analysis involves a detailed examination of a single case, focusing on its individual characteristics and elements. This approach helps to gain a comprehensive understanding of the case by analysing all its aspects separately. In contrast, for example cross-case analysis entails comparing multiple cases to identify similarities and differences across them. (Eriksson & Kovalainen, 2016, p.143) 38 Yin (2018, p.168–173) outlines four general strategies for data analysis: relying on theoretical propositions, working your data from the ground up, developing a case description, and examining plausible rival explanations. For this study, I have chosen the first strategy, which emphasizes pre-existing theory and examines its manifestation in different context, here the context being large companies and SME’s. The central proposition in this research is "Whether the factors influencing strategy implementation manifest differently in smaller enterprises compared to larger ones, considering variations in the factors affecting to the strategy implementation process”, which helps to organize the analysis by directing attention to the description of specific conditions within a particular context (Yin, 2018, p.168–169). For the analytic technique, Yin (2018, p.175–199) presents several options: pattern matching, explanation building, time-series analysis, logic models, and cross-case synthesis. As this is an explanatory study that asks, “How do success factors and challenges of strategy implementation differ in smaller and larger firms?” and aims to contribute to the existing theory, the pattern matching technique is chosen to be utilized in this study. In this approach set of patterns will be defined based on the initial findings and assess the presence of these conditions in the findings of the group of smaller case companies to draw conclusions regarding the overall proposition. This technique can be challenging, as the failure of even one proposition to hold true in a particular small company may prevent us from making conclusive judgments about the claim either way. Nonetheless, this technique was selected for the present study, as it is believed to yield stronger results than, for instance, cross-case synthesis, which would illustrate differences between cases but might not allow for the identification of reliable emerging patterns. (Yin, 2018, p.175) The data analysis begins by identifying key themes (factors affecting SI) within each case company. As a first step, a table is populated based on the thematic framework presented (table 2, p.16), completed separately for large and medium-sized companies, and for small and micro-enterprises. The table is then expanded to include additional 39 significant themes that emerge from the data. The matrix supports the research objective of comparing success factors and challenges across firms of different sizes and supports the theoretical framework (literal replication) alongside findings that reflect theoretical replication, enabling a structured comparison aligned with the research question (Yin, 2018, p.166). Thus, the themes are cross-examined between larger and smaller case companies to identify underlying patterns, points of convergence and divergence, as well as notable differences across organizational sizes. Significant observations and insights are highlighted, and their relevance will be assessed across the different comparison groups to provide a deeper understanding of the dynamics of strategy implementation in case companies of various size. 3.8 Validity and reliability Reliability refers to the extent to which research results can be consistently replicated when the same study is conducted multiple times. If other researchers can replicate the study and obtain similar results, the study can be considered reliable. Validity refers to the accuracy and credibility of the conclusions drawn from the research. In qualitative research, validity is concerned with ensuring that the descriptions and conclusions are precise and well-supported by evidence. This is achieved through rigorous analysis and by considering the research from multiple perspectives. (Eriksson & Kovalainen, 2016, p.305-307) Reliability in qualitative research is often debated due to the differences in how research findings are generated (Eriksson & Kovalainen, 2006, p.305). However, in this study, the consistency of results is maintained by ensuring that the same theoretical framework guided all interviews, and the findings are grounded in evidence collected from multiple sources. In interpretivist studies, credibility can be established by employing triangulation methods to verify findings from multiple perspectives (Steenhuis & de 40 Bruijn, 2006). Triangulation, a common technique in qualitative research, employed in the study, means that evidence is gathered from various empirical sources and cross- checked to confirm its consistency and accuracy (Eriksson & Kovalainen, 2006, p.306). This approach enhances both the validity and reliability of the research by verifying the consistency and correctness of the conclusions drawn and increases the construct validity (Yin, 2018, p.43). To further enhance the quality of the study and increase its construct validity, a draft of the report will be shared with the interviewees for their review, to ensure that nothing has been misinterpreted. Any necessary corrections will be made based on their comments. This also provides the interviewees with an opportunity to elaborate further on the topic and contribute additional evidence in case certain aspects were unintentionally overlooked or not addressed during the interviews. (Yin, 2018, p.43,241) Given that literal replication is employed to ensure consistency in outcomes across multiple cases, with the expectation of similar results, it serves to strengthen the reliability and credibility of research findings and thus increases the external validity of the study (Church, 2002; Yin, 2018, p.43,55). This approach will be applied to examine how well the established theories of strategy implementation hold true across different cases in this study. In addition to serving as the primary analytic technique in this study, pattern matching contributes to strengthening the internal validity of the case study. A key requirement of the pattern matching approach is the consideration of rival explanations. This means that when a pattern is identified in the data, alternative and plausible explanations must be acknowledged and systematically ruled out. It is essential to ensure that the observed outcome is not attributable to a different, equally reasonable explanation than the one identified in another case within the same pattern. The objective is to identify all potential threats to validity and systematically verify that no other plausible explanations exist for the assumptions made. (Yin, 2018, p.177) 41 4 FINDINGS 4.1 Within case description In the following section, the key factors influencing strategy implementation are examined through the lens of the case company. In addition, selected elements from the “other significant factors” category have been included where they were observed to have a distinct influence on the case company. 4.1.1 Case company Alpha Case company Alpha, a privately held Finnish construction group, operates primarily in Finland's key growth regions and has grown to become one of the largest players in its sector. Its business spans residential, commercial, and renovation construction as well as real estate development. Structurally, Case company Alpha functions as a parent company with multiple regional subsidiaries, where centralised support functions are coordinated at the group level. (Company web page, n.d; Panel interview P1) The interviewee, one of the founding members and the company’s first CEO, stepped away from the company’s operations 2021 and reflects on the company’s journey from its founding to his departure. (Panel interview P1, 2023) Clarity and precision in strategic foundations. Alpha’s strategy work evolved significantly alongside its growth. Initially, strategy was intuitive and owner-driven, focused on financial targets and communicated superficially. As the company expanded and established subsidiaries, strategy became more structured, supported by an experienced external board member. From 2015 to 2018, strategic goals were clearly documented and discussed through regional strategy days, fostering broader organizational engagement. Strategic competence was deliberately brought into the 42 board through the recruitment of individuals with experience from larger corporations, which added professionalism and structure to the strategy process: “We brought in someone to the board who had done strategy work in many larger companies.” By the early 2020s, Alpha’s strategy work had become fully professionalized, with subsidiary-level strategies aligned to group objectives, systematic monitoring, and strategy integrated as a central tool for guiding leadership, culture, and organizational coherence. Leadership and management capabilities. One of the key drivers of successful implementation was the visible and consistent commitment of the leadership team. It was seen as essential that management endorsed the strategy and actively embodied it in their behaviour and communication. As noted in the interview: “We showed that we were committed to the strategy ourselves. This was a prerequisite for others to take it seriously.” This leadership-by-example approach helped translate abstract strategic goals into concrete, everyday behaviour, reinforcing alignment across levels. Over time, leadership capabilities transitioned from being concentrated in a few key individuals to a more institutionalized and distributed form of strategic governance. Communication and information flow. Initially led by the CEO, strategic communication evolved into a significant, continuous, interactive process involving the entire organization. The CEO alone spent weeks each year personally communicating the strategy to different units and teams, adapting his message to smaller groups to ensure understanding. This personal engagement became a critical enabler of strategy diffusion. Responsibility for implementation was gradually distributed. Local unit directors and subsidiary CEOs took on more structured roles in delivering and following up on strategic objectives: “The regional directors and unit CEOs were responsible for making sure the message stuck locally.” 43 In addition, regular quarterly meetings engaged personnel across units in reviewing strategic progress and identifying necessary adjustments. This open dialogue was supported by intranet-based communication, emphasizing clarity, repetition, and transparency. Resource allocation. As strategic awareness matured, more attention and internal capacity were devoted to implementation. One of the most important resources was time, particularly that of senior leaders. Regular strategy sessions were scheduled, and managers were expected to organize follow-ups and performance reviews aligned with the strategic framework. A recurring theme in the interview was that resource allocation improved primarily through experiential learning. Over time, strategy implementation came to be seen not as a side activity but as a core managerial responsibility: “Eventually, we realized this needs to be part of how we lead the company - constantly, not occasionally.” Strategy awareness. In the early stages of case company Alpha, strategic awareness was exceptionally strong due to the shared history among staff, as most employees had transitioned together from a previous organization. As the interviewee noted: “92% of the staff came with us - we all knew each other.” This cohesion meant that strategy was implicitly understood without formal communication. However, as the company expanded and hired people from diverse backgrounds, maintaining alignment required more structured efforts. The organization began actively reinforcing strategy awareness through communication and engagement. As the interviewee explained: “We had to work harder to ensure new people really understood what this company is about, and it took more time, more dialogue and more structure.” Guidelines for implementation. Each subsidiary's strategy was reviewed systematically by the parent company’s board to ensure alignment with the overarching corporate strategy. These structural mechanisms helped translate strategy from an abstract plan 44 into a practical, governing framework across the organization. However, in the early years, such structure did not exist. The interviewee described how the implementation process initially lacked formal planning altogether: “The plan was me.” The organization gradually moved towards a more systematic model, with clear implementation schedules, defined roles, and organizational routines. The interviewee emphasized the importance of this shift in hindsight: “One of the most important lessons was that you need to be well-prepared before introducing strategic changes, there has to be a plan for how to communicate and implement it.” Reward systems and strategy implementation. The case company implemented a reward system that was deliberately simple and transparent, and according to the interviewee, it was precisely this simplicity that made it effective. Performance-based bonuses were tied to the financial results of each region or subsidiary, creating clear, localized incentives. As the interviewee noted: “We had a very simple performance-based reward system… people always get disappointed if it’s too complicated.” According to the interviewee, this straightforward model avoided unnecessary complexity, which could have undermined trust or demotivated employees. It allowed the company to incentivize performance in a way that matched its operational culture, results-driven, fast-paced, and grounded in trust. Additionally, it also allowed people to clearly understand the link between collective results and personal or team rewards. Corporate culture and strategic goals. Organizational culture was central to Alpha’s early strategic success. The founding team and most employees had previously worked together in the same business unit, bringing with them shared practices, trust, and mutual understanding. This strong cultural cohesion laid a solid foundation for strategy implementation in the company’s formative years: “We were kind of like one big family… we had the same goals.” 45 Alpha’s core values of honesty, openness, and people-centricity were actively demonstrated in leadership behaviour and daily operations. Rather than being abstract ideals, values were enforced through consistent actions, creating a strong cultural framework that supported strategy implementation. As the interviewee noted: “Even though the strategy was basic at first, people still understood what we were doing. That’s because we all came from the same background.” As Alpha expanded and hired employees from diverse organizational backgrounds, its previously cohesive culture began to fragment. Different work habits and expectations led to the formation of informal subgroups, making strategic alignment more challenging. To maintain clarity and cohesion, the leadership team had to invest more in personal engagement and communicate values and strategy in smaller group settings. As the company evolved into a network of semi-autonomous units, it became evident that the original informal cultural model was no longer sufficient, and a more structured approach to strategy was necessary. Other significant factors outside the framework Challenges regarding organizational structure and decentralization. As case company Alpha expanded and introduced a subsidiary structure, the strategic implementation process became significantly more complex. Initially, strategy could be managed centrally due to the organization’s “small size” (as the interviewee described it, although, by definition, the company was medium sized already at the founding stage) and cultural homogeneity. However, once multiple semi-independent units were established, each with its own leadership and local operations, coordination challenges emerged: “At some point, it stopped being one company, it became regions, units, with their own strategies that had to align with the corporate one.” The interviewee recognized that this decentralization introduced friction and increased the need for synchronization: 46 “We had to make sure each unit’s strategy was in sync with the group strategy, not always an easy task.” Consensus and commitment. Strategic alignment within the leadership team was consistently strong. Although there were occasional disagreements, these were resolved through open dialogue: “If we disagreed, we handled it behind the scenes - nothing ever lingered... We were always aligned on the overall direction, even if we saw things differently along the way.” According to the interviewee, this ability to maintain open internal dialogue and reach agreement was critical for strategic clarity. This consensus within the leaders created a stable foundation from which strategic initiatives could be launched and maintained. Beyond leadership, employee commitment was seen as essential to successful strategy implementation. In the early stages, strong cultural and operational cohesion meant that strategic alignment was largely implicit, as long-standing team members shared a common understanding without formal articulation. The interviewee emphasized that true commitment stems from understanding, not instruction, highlighting the importance of transparent communication in building genuine engagement. Employee engagement. The implementation of strategy at the case company was closely tied to employee engagement, even though employees were not directly involved in the actual formulation of the strategy. The leadership actively involved personnel by facilitating dialogue and requesting feedback: “We always asked for feedback on the strategy and people could comment freely.” The CEO (later the chairman of the board) made a point of visiting all regional offices quarterly and holding sessions that invited participation and reflection: “We discussed whether anything needed to change, sometimes the feedback came weeks later by email, but it came.” 47 The interviewee believed that this inclusive approach fostered a stronger sense of ownership among employees and contributed to their understanding of the company’s strategic direction. 4.1.2 Case company Beta Case company Beta is a privately owned Finnish indoor climate technology company that has experienced significant growth since its establishment. Headquartered in Southern Finland, the company specializes in ventilation, heating, and cooling solutions, including maintenance, modernization, and lifecycle services. Its operations are concentrated in urban growth centres where the demand for technical building services is high. The company is structured as a group and is centralized under the parent organization (Company web page n.d.; Panel interview P2, 2024) The interviewee has served as the company’s CEO for many years and played a central role in shaping its early growth and strategic direction and recently he has transitioned from the CEO role to a more focused position where he is currently responsible for overseeing acquisitions. (Panel interview P2, 2024) Clarity and precision in strategic foundations. Case company Beta has developed the latest clearly defined strategy for the years 2022–2027, formulated in collaboration with the consultancy firm PwC. This process lasted five weeks and involved multiple senior leaders, indicating a structured and collaborative approach. The strategic plan includes specific objectives such as market positioning and geographic focus: "The strategy covers the years 2022–2027 and includes, among other things, the company's goals in the market, such as whether to be a generalist or a specialized player, and in which geographic areas the company wants to operate." The interviewee highlights the importance of having a clearly defined and well- structured strategy to guide organizational direction. He also emphasizes that strategy should be actionable and embedded in the organization’s everyday operations. 48 Leadership and management capabilities. The interviewee reflects on the leadership within his company and highlights the importance of experience among those in managerial roles. He considers experience essential for those in leadership positions, as it enables them to better understand complex situations and make well-grounded decisions: “I truly believe that experience plays a central role in leadership. It allows you to see the bigger picture and make more informed decisions. The interviewee emphasized that effective leadership is rooted in authenticity, inspiration, and adaptability. Leaders must genuinely believe in the company’s vision to inspire others and foster commitment. He cautioned against aggressive, purely results- driven leadership styles, which may produce short-term gains but lack long-term sustainability. Instead, he stressed the importance of empathetic leadership that acknowledges the varied capacities of employees to adapt to the pace of strategic change. Additionally, he highlighted that strong leaders are those who learn from their mistakes, internalize the lessons, and adjust their behaviour to avoid repeating them, reinforcing a culture of continuous learning and responsible leadership. Communication and Information flow. The interviewee emphasizes the importance of internal communication in enabling strategy implementation. Various formats, such as onboarding, team events, and informal gatherings, are used to communicate company goals and direction. He describes how transparency and regular dialogue have been key practices, even during challenging times: “We have these briefing sessions… even during the pandemic we met face-to-face, with things like Friday pizza gatherings and all kinds of events. We keep communicating it all the time and let people know where we are, what we’re aiming for, and why.” To ensure that strategic communication is effective, clarity and simplicity are key. The interviewee recalls how a 176-slide presentation was eventually condensed into a single, easily understood visual: 49 “The strategy has to be simple - it can’t be a hundred pages long…The message must be accessible to everyone, not just senior leadership.” Resource Allocation. At case company Beta, strategic implementation is tightly linked to forward-looking resource and personnel planning. The company focuses on identifying the expertise required to support growth and address operational needs. Budgeting plays a central role in translating strategic goals into action, functioning as a financial tool and as a mechanism for alignment. As the interviewee stated: “Strategy is a great idea, but when it comes to execution, the budget is what makes it possible - or impossible…To ensure alignment we break the annual budget down to monthly and unit levels.’” At case company Beta, resource planning is dynamic and adjusts to changing needs across business units. Although planning is rigorous, it remains flexible and responsive to operational realities. A key challenge is the shortage of skilled labour, which has led the company to invest in internal training programs as a long-term solution to secure future talent and support strategic growth. Finally, the company supports flexibility by enabling collaboration between units. Unit managers and regional directors actively share resources and expertise to avoid duplication and inefficiencies. Strategy Awareness. The interviewee emphasizes that strategic awareness is actively built from the very beginning of the onboarding process. New units and their management teams are introduced to the company’s strategy during orientation, where key strategic themes are broken down and contextualized: “The strategy is communicated to all employees and new companies during orientation…We also run a dedicated onboarding session for the management of each new company where we go through the same strategic content.” Despite consistent communication, the interviewee acknowledges that it is not always verified whether the message has been internalized across the organization. This 50 realization led the interviewee to reflect on the need for more systematic methods to assess whether the strategy is truly understood across the organization. Finally, he points out that in different units or roles, the strategy may be perceived differently depending on their operational focus. This highlights his view on how local interpretations and strategy awareness can deviate from the central narrative. Guidelines for Implementation. The interviewee describes how strategy implementation at the case company is structured through practical planning processes that emphasize realism and adaptability. He views the annual budgeting cycle as the most important structural framework guiding implementation, as it transforms strategic goals into actionable, measurable components, which translate high-level strategy into measurable outcomes and are supported by KPIs and local-level ownership. However, beyond budgeting, he highlights several interrelated practices that support execution across the organization. In addition to strategic planning and communication, each business unit creates its own annual action plan. These include specific targets and resource needs, and in some areas, such as sales, concrete metrics are defined. Reward systems and strategy implementation. While the interviewee does not emphasize formal performance-based bonuses, he outlines a clear link between strategy implementation and measurable targets. These include financial indicators such as revenue and EBITDA and non-financial metrics like employee satisfaction, customer satisfaction, and ESG goals. As he explains: “Measurable goals include increasing revenue and EBITDA… employee satisfaction and customer satisfaction are also very important.” A key element supporting strategy implementation at the case company is equity-based ownership. Offering shares to key personnel has strengthened strategic alignment and commitment by tying individual success to the company’s overall performance. This long-term incentive structure encourages cross-unit collaboration and replaces short- term bonus schemes. With a planned private equity exit, shared ownership ensures that 51 those involved in execution benefit directly, providing a stable and unifying motivator for long-term strategic success. Corporate culture and strategic goals. The organizational culture of the company has been strongly built around an entrepreneurial spirit and a hands-on approach. Historically, the culture has been characterized by a strong reliance on individuals: trust in the entrepreneur(s) as a person(s) and confidence in the company’s ability to provide employment and continuity. As the interviewee describes the early phase: "In a way, there was trust in the person, in the entrepreneur, that they would be able to provide you with work and manage things." During Beta’s growth phase, the culture has remained fundamentally the same, but mergers and rapid expansion have introduced greater diversity. Companies and personnel from various backgrounds have brought their own practices, and maintaining a unified culture has required active management and communication efforts. As the interviewee notes: "We are bringing in many different cultures, seven last year and six the year before. We are constantly kind of in a state of fermentation [i.e. continuous phase of change]." Other significant factors outside the framework Cross-unit collaboration & coordination. The interviewee emphasizes the importance of creating a shared sense of purpose across the organization to mitigate risks. In this context, employee ownership plays a critical role: “We have over 60 key people who are shareholders. That really hel
