Based On The Activity Diagram-driven Software Requirements Analysis Methods And Applications

All the government departments, large enterprises, have their own information departments. When these enterprises choose to invite other professional software corporation to build a custom Management Information Systems, these information departments usually have to communicate the business experts of their own enterprise and the technical experts of the chosen software corporation , just like a bridge. In some case, some Project-Management techniques and some software engineering methods should be used. By analyzing software life cycle model, requirements analysis and design methods and software testing, this article find out some extraordinary methods for the specific groups.By using the methods of analysis, summed up, experimentation and so on, a variety of integrated software engineering theory and methods was mixed up, some easy-to-use tools was chosen, to cut into a set of specific occasions: the technical staff for working methods, which named"a software requirement method that based on activity-diagram-driven".At first, by analyzing the Waterfall Model, the Rapid Prototype, the evolutionary model, the Spiral Model, and the Interactive Model, with practical, the MIS project life-cycle model of the special team was build. According to analyzing various life-cycle models, the team's focus of the work should be the Requirements Analysis and Function testing.Then ,by analyzing the process-oriented and object-oriented A&D methods, UML (Unified Modeling Language,) RUP (Rational Unified Process), XP (Extreme Programming), and other methods of Requirement Analysis, ingenuity put forward a software requirement method that based on activity-diagram-driven. This method look upon "Activity Diagram" as the central idea, thick-grained analysis of business processes, thin-grained analysis of business logic, Differentiate Business description and the function requirements description, to find out requirement is important than to find out errors by user, it is important to creating an effective feedback mechanism. Finally, the method that based on activity-diagram-driven was practice in the hardware management platform project.
