Abstract: The present invention provides a data linking method, for use in design development work, that solves the problem of the need to re-enter data or of a delay in reflecting data that may occur when a progress management unit, a review management unit, and a pending issue management unit for work items perform operation independently. The method according to the present invention creates a review report template including review items defined by a review report management system and pending issues registered with a pending issue management system, extracts pending issues and approved information from a review report created based on the review report template, registers the extracted pending issues and information with the pending issue management system, calculates a solution status and a discussion status of the document from the review report, and registers the calculated status with an work item management system.
