Subproject A4: Collaborative Requirements Engineering for Product-Service Systems

Subproject A4 is concerned with the question how cycle-oriented collaboration in requirements engineering for product service systems can be organized. The central issue in this context is that the development of product service systems involves various disciplines and stakeholders. Insufficient or unsystematic collaboration between stakeholders causes many delays in the requirements engineering process. A comprehensive approach for requirements engineering for product service systems therefore needs to consider collaborative aspects. For this reason, subproject A4 develops models, methods and tools for designing organizational structured, business processes and information systems that support coordination, communication and cooperation in the area of collaborative requirements engineering.

• PSS-Integration Framework (developed in a cooperation of the subprojects A4, A6 and C2) 
  • Cross-disciplinary approach for integrating heterogeneous models and artifacts of PSS development 
• Cycle-oriented Traceability Model for PSS Requirements 
  • Structural model of artifacts and semantic relationships (trace links) that are relevant in PSS development
• Traceability-Process Model and Method Toolkit 
  • Specification of activities that are required to ensure traceability 
  • Description of methods for performing those activities 
• Software prototype of a traceability support system
  • Automated model transformations and linkages
  • Features for analyzing trace links

• Comprehensive Approach for Requirements Engineering in cycle-oriented Innovation Processes of Product Service Systems, consisting of: 
  • Reference model for collaborative Requirements Engineering         
  • Governance instrument to support coordination         
  • Communication toolkit to support communication        
  • Approximation method for defining the overall PSS goals to support cooperation 
  • Software prototype of a collaborative Requirements Engineering system
