Toward the digitalization of product development process to vitalize the Japanese strength of design and manufacturing, the importance of process study by the criteria of digital data and the factors to consider were revealed, And also the necessity of the spiral up process from the upstream design to downstream the manufacturing with the consistent information coordination was revealed. In this report, the necessity of the systemization for enabling feed-forward coordination of real product information in the process of purchase, preparing production and production itself with virtual product information in the process of planning, development and design is revealed. And an ultimate mechanism of utilizing information for designing and manufacturing product in order to vitalize the Japanese strength of them is revealed, that is the system design philosophy of "Engineering Process Integrated Architecture (EPIA)" to enable the mutual coordination between the systems of PLM/SCM/CRM.
