Abstract
In order to prevent project trouble or to repeat project success, enterprises have developed their own QMS (Quality Management System) for project management. However, these improvement activities are performed in individual business units, obtained knowledge were not shared across business units. In this paper, we describe methodology for extracting and organizing project management knowledge, which is developed through real practice for extracting and organizing them. Especially, we made fundamental concept based on commonalities, differences and specialties. Also, we developed "knowledge extracting worksheet", "knowledge description sheet" and "knowledge map" as supporting tools as well as procedure for extracting and organizing knowledge, through three trial cycles of real practice.
