The current study introduces the concept of new product and service portfolio (NPSP) advantage by creating and validating a three-dimensional measurement method that reflects novelty, meaningfulness and superiority – the three characteristics of NPSP advantage. Based on industry-wide homogeneous generalizable quantitative data from 108 manufacturing companies, the results indicate that these three characteristics of NPSP – novelty, meaningfulness and superiority – are distinct characteristics that together constitute NPSP advantage. This paper contributes to the literature on new product development, as its findings suggest that when measuring the concept of NPSP advantage, the three-dimensional construct that includes the three aforementioned characteristics has a better fit to the data than the unidimensional structure. Because it considers both new products and services, the current study offers an integrated approach to measure the desired innovation process outcome (NPSP advantage). In this way, this paper bridges the research on new product development with that on new service development.
