Abstract
Complexity and rapid delivery requirements make project management difficult. To meet deadlines, it is essential to promptly identify problematic elements of a project, and to take immediate corrective actions. To realize this, the latest progress has to be obtained. However, time management based on reported progress has two problems. One is that it takes a lot of time to obtain progress The other is that the reported progress may not be in touch with the actual condition of deliverables. These issues are critical, especially in large projects whose development sites are distributed. This paper presents measures for assessing progress based on the actual conditions of deliverables in a timely manner using PRO-NA VI which supports project management.
