The Research on Viewpoints Requirements Description Method under Time-Varying

摘要

In this paper, using viewpoint template we define the viewpoints requirements description method under time-varying, and add requirement identifiers to viewpoint template, to record in detail the changing requirements with development of the target software system, and to effectively reduce the degradation of requirements information. This method can comprehensively extract requirements from different project stakeholders in different period of times, form complete requirement specification and preferably guide the software development. We also propose the process of viewpoints integration, based on viewpoint templates with requirement changing with time.
