Recently, the approach extracting project management knowledge from these improved mechanisms and sharing them across business units are started in our organization. In this report, an IT system, that facilitate to collect and to share project management knowledge, is described. At first, both collecting process and using process for the project management knowledge are defined, and then the obstructing issues and countermeasures against them are identified. In addition, a prototype of PM-Knowledge-Viewer with supporting functions such as knowledge navigation, user's evaluation, knowledge request, and case collection, has been developed.
