It is very important for our company to enhance management skill of our project managers who run over 500 projects in Japan and overseas. As a matter of fact, their management skill levels are various because of their abilities and carriers. However, the same level of management ability is required to assure and establish excellent quality of our "Products" and "Projects". We utilize a set of standard manuals called "Chackage" in which the tasks of project manager are broken down, analyzed, categorized and described in "work flow", "work package" and "management document" in detail. In this my presentation, I will explain the preparation process, the contents and the management philosophy of this "Chackage" standard manual. At the same time, I will compare it with PMBOK for its future updates and revisions.
