Requirements Analysis In Software Development And Change

Software requirement analysis and change is the base of the project development, it is also the most important key in software life cycle. How to strengthen and improve the software requirement analysis and change in the development is the target of this article.Based on deep investigation, here the author proposed the process of the requirement analysis and change and the way to enhance the requirement management, then introduced the software requirements change control strategies, including rapid prototyping and incremental iterative model of software engineering methods, by analyzing the GQM model, a measure of demand management framework. It elaborated the defects enlargement model, changes impact assessment model, the control method of stability requirements changes, requirements changes measure and other functions. Finally, it described requirement evaluation and confirmation.This article combines the actual instance to analysis requirements change with the detailed procedures and processes to improve the effectiveness of system.
