The phase of crucial importance in most product development projects is the front end, often called “Fuzzy Front End” (Koen et al., 2001; Kim and Wilemon, 2002). Here the decision is made which projects will get resources and which ones won’t. Additionally, several studies indicate that a major part of the product-development costs heavily depend on the decisions taken in the front end (Herstatt and Verworn, 2003).
