Then, based on this level definition, we grasped the transition and the current state of the process assets sharing, and deploying the approach to the step-by-step improvement of organizational utilization. In this paper, we introduce issues of SI vender's information sharing, the progress of the process assets sharing based on the information sharing level, and future outlooks.
