Abstract
To make a good use of the difference of behavior and thought between high and medium achievers in project management, which was found in our previous research for human resource management, a case method for younger managers who were expected to manage a big and complex project was designed. The main characteristic of the method is to use two kinds of persona each of which represents high or medium achievers' behavior and thought. Both personas were given as of ITSS-high level (level 6) managers. The use of personas would avoid divergent or biased discussion among less experienced participants and activate analysis and critical discussion of advantage and disadvantage of each persona through quasi-observation of their responses to the case. After the discussion they were required to relate what was learned to their own work practice and share it each other. At last the previous research was explained. This case method aims to promote transformative learning in which the participants reflect their own styles and activate their expansive transformation through a quasi-encounter with different management styles of senior managers and critical but sense-making discussion.
