Abstract
It is not heard that the standardization of development process has succeeded. I arranged why the development process standardizing project does not work to three points. I think that the plan based on these three reasons drives the project successful. In this paper, I propose the practical planning method, corresponded to the process groups and the knowledge areas in PMBOK. And this method is effective also in the proposal activities of the project above, since it is relevant to the initiating and planning process group. Although there are still several projects which applied this proposal, the effects have shown up in them.
