Abstract
Our company has tackled suitable support of company organizations, such as standardization and increase in efficiency of a management process, and a substantial support organization (PMO), towards extermination of an unprofitable issue, or improvement in a project strike rate. Moreover, in order to raise the excellent project manager who utilizes them and can lead a project to a success, promotion of qualification acquisition and fullness of a project management educational lecture have also been tackled. However, it is in the present condition which an unprofitable project generates. Then, effective experience and know-how (Takumi no Waza) were collected from the excellent project manager with experience of a success. By changing it into manual knowledge from tacit knowledge, it was considered whether it would be unutilizable for training of a project manager. As a result, a manager's tacit knowledge has been built as a "project management practice manual."
