Abstract
On the system development project, secure of quality is one of the matters of weight related to the success or failure of the project. It is said that the prevention of not causing defect in addition to detecting and planning for defect is effective to enhance the quality. But we think it is in the situation in which a preventive measure cannot be held enough on the site of actual system development. It is thought that it leads to steady project management and the improvement of the development production by improving this. In this report, we report our preventive measure by "Self checklist" that we did on the project, and after the defect that remains since the development process is analyzed, we consider the measure of the defect prevention on which the project administrator should work in the future.
