Abstract
As one of the important elements which influence a success and failure of a project, team management attracts attention. In today's world, projects become more complex and much larger. So a project manager (PM) should have all leadership capabilities in order to build/keep high teamwork. In general, it is very difficult that a project manager owns, in oneself, every leadership capability that is indispensable for performing a project. That is, most project managers have incomplete leadership capabilities. According to the situation of a team (namely, project team life cycle), it is necessary to get some important leadership capabilities in order to perform a project. We consider a project team life cycle that dividing into five stages is appropriate based on precedence research. We have researched required leadership capabilities according to each of these stages for years. We view leadership as a set of four capabilities: sense making, relating, visioning, and inventing. This paper reports the application result in a certain project.
