Research And Application On Software Requirement Analysis Based On Agile Modeling

Software requirement analysis is the most important step in software engineering’s life-cycle. However there are two major defects of traditional requirement modeling methods. One is frequent requirement ambiguity and discord caused by informal requirement description. Therefore it is hard for identification and confirmation. The other is changeability. Requirement change and its chain reactions are the most influential risk factor for the project quality, process and contract performance. And because of the agile modeling is a new modeling through which is able to adapt to the changes in requirement and improve the efficience in the software developing. So this essay focuses on dealing with the difficulties of software requirement analysis. It put forwards a setof formal requirement analysis methods on the basis of agile modeling through the combination of formal method and agile modeling theory.The essay comprehensively researches the agile methods and the development process of it and puts forward Agile Requirement Analysis Modeling based on agile idea. Agile Requirement Analysis Modeling as the practical supplement of agile methods in the software requirement analysis can meet the target of CMMI and offer reference about the guides to action for small and medium-sized software development organizations, especially for the electronic commerce.In this paper, a mall-sized electronic commerce system’s developing process will be presented as the background to analyze the agile modeling,use theagile development methods from the beginning to the final completion of theproject and use a variety of modeling tools and to complete the developmentof this project as smooth as possible.
