Abstract
Failures in project management make negative impact into business. Never to recur same type of project management failure, it is essential to analyze the root of causes of failures in project management, and take preventive actions against these failures.Therefore, we had started to share lessons-learned from project management failures across business units. At first, in order to share lessons-learned, we investigated how failures and lessons-learned are described in each business unit. We collected 65 analyzed and described lessons-learned from 31 projects in 8 business units, and re-analyzed them. As a result, we found that some of the results of cause analysis were not enough to take preventive actions against failures. Furthermore, we found that there were 5 patterns of ill descriptions of lessons-learned. We proposed common lessons-learned describing template, to analyze project management failures, to derive preventive actions against them and to share lessons-learned across business units, as considering these 5 patterns.
