Requirements from the Void : Experiences with 1:10:100

In this paper we discuss our experiences with the 1:10:100 approach for organizing requirements elicitation in open innovation projects. 1:10:100 was originally developed to tackle the complexity of ‘wicked’ design problems, but also turns out to be a helpful means to organize requirements oriented project conversations with heterogeneous groups of innovation partners. We use the 1:10:100 approach to shape project phasing. We discuss the approach, report on our experiences using 1:10:100 for requirements elicitation in two service design projects in the context of health care, and based on this present some practitioner’s guidelines for using 1:10:100.
