Evaluation of an idea generation method and its supporting groupware

KJ method is a well-known idea generation method in Japan. We propose an evaluation method for compositions of B type KJ method (i.e. conclusive compositions of the KJ method). The method consists of “a pair comparison” for evaluations of contents and Petri net graph for evaluations of structures. We applied the method to evaluation experiments of compositions, and compared the results, and then we discussed the evaluation capability of the method and some structural features of compositions of B type KJ method. The results of evaluation experiments represented that contents of compositions of B type KJ method were superior to those made without the KJ method significantly and that structures of them were also significantly different and the performance of GUNGEN was almost equal to that of a conventional method on paper
