A Context-based Requirements Analysis Method for PSS Design

Focusing on the importance of considering value-in-context, this research aims to formalize how the concept of context should be handled in Product-Service Systems (PSS) design.In PSS design, it is important to combine products and services appropriately based on customer requirements. For the requirementsanalysis, specific situations in product useshould be clarified considering customer context. However, there is no method to extract elements of customer context in existing PSS design methodologies. This paper proposes a framework whichclassifies viewpoints for extracting the elements of context. Based on the framework, a context-based requirements analysis process is also proposed.
