Abstract
Scenario Graph is one of Forced Association Measures and also one of structured mind mapping methods to generate potential scenarios for new products and services while visually organizing contextual information. In previous study, the effectiveness of the Scenario Graph for individual person is validated. In this paper, we transfer the Scenario Graph from design by individual person to design by group and show its effectiveness. We compare group workshop results of idea creation between the Scenario Graph (as a test group) and a group Brainstorming (as a control group) - to solve an identical problem. The test group, which used the Scenario Graph, yielded more ideas than the control group, which used the Brainstorming, did. Moreover the ideas of the test group were newer than those of the control group, too. Our experiment result suggests that the Scenario Graph by group is effective as same as by individual person in improving the performance of idea creation.
