The world industrial economy has turned into an economy of service over the past two decades. Evidence can be easily found, such as the shift of more and more manufacturers from traditional product-centered logic towards a ser-vice-centered logic. Transactional business models are evolving towards recur-ring revenue models, which raises questions about the new value proposition to be met. The addition of complementary services to the product to maintain, among other things, the performance of assets throughout the whole PSS life cy-cle presents both an opportunity and a complexity. To make this integration sus-tainable, we suggest operationalizing the PSS concept so that the value proposi-tion is customer oriented, considering simultaneously the engineering of the of-fering, the processes, and the support network. We suggest developing scenarios of new value propositions based on service value process models. Our contribution will present a three-dimensional engineering framework as well as a service process value model.
