Abstract

Purpose – Nowadays manufacturers companies are increasingly compelled to navigate towards servitization. Different methods and approaches were proposed in literature to support them to switch from traditional product-based business model to product service systems (PSSs). However, new knowledge, capabilities and skills were needed to consistently develop PSSs, since they need a joint focus on both customer’s perspective and company’s internal performance and at the same time a proper support for the integration of product and service design. The purpose of this paper is to propose the Product Service System Lean Design Methodology (PSSLDM), a structured methodology to develop PSSs along their entire lifecycle. Design/methodology/approach – Retrieving concepts from interpretative, interactive and system development research traditions, and strongly reminding the design research methodology framework, the adopted research methodology is composed of three main phases (observation and conceptualization, theory building and tool development, validation) and involved three heterogeneous companies. Findings – This paper provides an overview of the PSSLDM, explaining how the different methods supporting its conduction should contribute to properly design an integrated PSS. Moreover, companies highlighted several benefits in the different stages along the PSS lifecycle deriving by the adoption of the PSSLDM. Research limitations/implications – The development of a platform based on the PSSLDM methodology raises a discussion on the possible changes needed by current Product Lifecycle Management (PLM) models and systems when they have to do with PSSs. Originality/value – The PSSLDM enriches the already proposed SErvice Engineering Methodology, introducing new several components linked by lean rules in each of its phases (starting from customer analysis, going through solution concept and detailed design, until the offering analysis) and better supprting the deatil design of both prodcut and service components.

Discussion and conclusions

This paper detected the leading gaps dealing with PSS design, evidencing the lack of methodologies able to support the integration of the product and service components since the early stage of the design phase. This is also justified by: a limited development of supporting tools able to bridge customer needs into technical constraints, a scarce adoption in the manufacturing context, the necessity of integrating actors from both product and service fields of knowledge to consider all the PSS features, a lack of an entire lifecycle perspective along the PSS development, a lack of dedicated methods able to enhance the coordination between the back-end and the front-end capabilities, the lack of a systematic design of product and service features as an integrated system. To overcome these limitations, the PSSLDM, a methodological framework and related supporting methods and tools for the systematic development and design of PSSs, has been introduced in this paper. It aims at creating a structured methodology for the design process and at fostering the collaboration between the different actors of the process. Grounded on already existing methodologies, the PSSLDM introduces new innovative aspects, from customer needs analysis to process prototyping, from process validation to offering identification and analysis, contributing to the PSS development context from both a theoretical and a practical perspective. In particular, in order to fill the gaps of the available methodologies, in the definition of the PSSLDM a particular attention has been given to: defining a method enhancing a better KM and supporting a matter integration between product and service design as well between concept and detailed design phases, and the introduction of the lean development concepts aiming at identifying and reducing wastes along the entire PSS development process.
