Abstract
We decided to establish the methodology, which based on the psychological types, that meets these three conditions: “academic formation principle”, “easily implemented formation method”, and “thorough consideration to ethical aspects”. As for the overall structure of the methodology, we have designed it with a three-layer structure. In phase I: a team formation methodology, we devised three methods. In phase II: a team management methodology, we devised three rules. In phase Ⅲ: a team development support methodology, we devised the education regarding the motivation and knowledge. We conducted randomized parallel group trials, and those results were analyzed using Data Envelopment Analysis (DEA) and scatter graphs. As a result, this method showed the effectiveness and possibility of future development.
