Research And Realization Of Requirement Changes Management System Based On JPBM

The whole software requirements engineering includes requirements development and requirements management two parts, requirements change control is the core of requirement management. Changes in requirements result from improper control of software project failure case (?)wing rapid growth potential, therefore, needs to manage and control the majority of changes have been standardized into a major software development company based management system into the process.Management needs without frequent changes very easily lead to loss of controlsoftware development process and ultimately lead to the failure of software projects, thereby causing the loss of multi-party, it needs to effectively control and managechange is very important.The project focuses on the following issues: 1,change process management software requirements. Only the development and possession of more facts to meet the company management processes, tracking changes to the whole process of change for the future to provide data to support change control, minimize the impact of the changes.2, change the workload of a qualitative needs assessment model, assessment by the evaluation model as close as possible to assess the value of the true value, try to avoid making errors reach or exceed 100% of the estimates. So that the model estimates in the software provide some practical guidance. 3, the establishment needs to change history tracking and statistical models for different projects and different stages of the project to establish the historical tracking database, and then statistical analysis of the library to the form of visual presentation to the users of the system. Changes for later analysis provides the basis of historical data..The practicefor the development of change management is not only feasible but also reliable, can effectively record and controlrequirements changes. At the same time the subject of research, development and application of the practice, summed up the software to further improve and perfect the methods for further research work has laid a good foundation.
