PURPOSE: To eliminate the lack of software developing staffs and to centralize informa tion and mutually utilize technical information by performing reserved logical dealings at proper time and proper places according to a software development reserved logical dealing function by regarding a theme and operation to be developed as reserved dealings.

CONSTITUTION: When software is developed in future, an orderer applies a software dealing place for reserved dealings so as to secure the developing power of an contractor. A membership system is employed for both orderers and contractors. At the software dealing place, the contents of the reserved dealing application are made open to contractor sides according to a dealing rules and intended contractors are tendered to decide the contractor. A procedure from future reserved dealings to actual development moves to actual development dealings according to a specific format. The authorization and registration, advertisement, contract breach, and others required for the process from the future reserved dealings to the actual development dealings are changed for the members. Therefore, a proper, smooth, and stable development system for software is obtained in consideration of current and future states and developing operation is promoted; and the developing power for a future theme can be reserved and secured at present.
