Evaluation of design for service innovation curriculum: validation framework and preliminary results

Designing product-service systems is challenging because of the broad and under-defined scope of the task. Design teams must integrate various solution elements, such as hardware, software, service, and infrastructure, while resolving the communication challenges among different domain-experts. Design for Service Innovation enables design teams to effectively deal with ambiguity and to communicate their ideas among team members and managers, as well as with customers through a common language. We validated the effectiveness of design for service innovation (DfSI) in both academia and industry. This paper describes the process and the preliminary results of the validation based on three approaches: hypothesis testing, voting and interviews.
