Abstract
Improvements of project management activities are desired in every business domain. Sharing project lessons learned across business units, can be an effective way to improve project management activities, on an enterprise composed of various business units. In order to share project lessons learned across business units, we collect 31 failed project cases analyzed in each business unit from 8 business unit, re-analyze them, and extract 50 sharable project lessons learned. Moreover, we design an analysis method to extract sharable project lessons learned, that reflects analysis know-how gathered from actually performed re-analysis activities.
