　In recent years, before the enterprise system development orders, user companies are required to submit RFP to system development companies. After the submission of RFI, RFP, the RFQ is conducted and final system development companies are selected. Then, work such as feasibility study, requirements definition exists, but the authors are aware that clear isolation of working process of these has not been made, and we have confusion in the system development. It is an object of the present study to be brought about problems that may occur therein, and the difference of definition in feasibility study and requirements are clear.
