This paper describes the role of "Production design" method to be expanding as a mean to control the information flow of a project. And it also defines "Production design" as a tool to control the product information flow and not as a mere information conversion tool from architectural drawing to technical or manufacturing ones. From the standpoint that the CAD and other information technologies will play the major roles to obtain a more controlled information flow during building construction, further studies will be conducted on these related to the "Production design method".
