During the design of integrated products and services, such as in a product-service system (PSS), an analysis of specific customer needs and the requirements to fulfil them is an important activity needed to determine value propositions based on the function, use, and result of products. Requirements modeling using the OMG Systems Modeling Language (OMG ™ ) offers a model-based systems engineering approach to documenting the functionality, performance, and interfacing of systems. However, to use modeling languages, there is a need to understand how the language meets the needs of the modeled system or domain. Following an initial review and evaluation of attributes of PSSs and existing approaches to modeling a PSS, this article analyzes the SysML requirements diagrams–as a technique for analyzing PSS requirements. SysML was compared against existing approaches to PSS modeling using the identified PSS attributes. Case scenarios of PSSs in the automotive industry were also applied to evaluate the use of SysML requirement diagrams. The article concludes by discussing implications of SysML for PSS researchers and managers.
