Abstract
We have established the integrated project management for handling the multi-vender project smoothly through practices of a large-scale multi-vender project. Recently, short-term multi-vender projects are increasing, so the integration project management for 'a short-term project' is increasingly required. In this paper we introduce know-how and examinations of short-term integration projects which we have obtained from experience of short-term multi-vender projects. These short-term multi-vender projects have been managed based on the integration project management.
