In practical lectures on software intensive business systems, we do not yet have an established method for determining what kind of personal characteristics and team compositions are most beneficial to obtaining the maximal educational effectiveness. Here, we propose a framework for analyzing the effects of personal characteristics of team members on educational effectiveness. We also apply the framework to an actual practical lecture. As a result, we find that it is better for a team to have members with a similar degree of tendency of conservative for acquiring more knowledge and skills and the team members have similar characteristics of progressive or conservative. It is expected that in similar practical lectures, we can also obtain the desired educational effectiveness if we can compose a team with the suitable characteristics as based on our findings.
