This paper summarises servitization research concerning product-service system design processes in the manufacturing industry, considering the overarching value chain. We used a methodological scoping framework to create a systematic overview of scientific papers in the context of the B2B manufacturing industry.
We identified five main topics: business models, organisational aspects, value creation, collaborative networks, and servitization strategies. Moreover, servitization research appeared to be concentrated in Europe, in particular in the United Kingdom and Nordic countries. We found only one paper that met all our selection criteria: service design and business model design within technology-intensive manufacturing firms, collaborating in networks and addressing end-customer needs. This research gap provides a direction for a further deep dive in what we call overarching Servitization; we will focus on designing product-service systems throughout customer supply networks.

Purpose: The objective of this study is to explore PSS design approaches for product-service innovation in the B2B manufacturing industry. This paper builds on current research within the Delft University of Technology, researching the role of design as a driver for change and servitization. Design/Methods/Approach: We studied 13 product-service design cases of ten weeks, carried out by students industrial design engineering. We collected the case data, observed their process and analysed the outcome of the project. We mapped the product-service proposals and built frameworks categorising levels of innovation and the applied strategic design elements and methods. Findings: Taking an overarching innovation approach, creating a broader perspective on the value chain, exploring new business contexts without being hindered by conventions and limitations and using state-of-art design methods, increase the innovation level of product-service propositions. Originality/Value: This study draws attention to the importance of strategic design processes in PSS innovation.
