Software Requirements Change Management – A Comprehensive Model

This chapter presents a research about the Software Requirements Traceability. The main elements of traceability, definitions, problems and prospects are presented. The chapter is organized by topics and its beginning is a review about requirements engineering, its categories (Elicitation, Analysis and Negotiation, Documentation, Validation, and Management) and its role in software development. Afterwards, the requirements management and its elements (Identification, Change Management and Traceability) are described. Traceability is discussed; its aspects and problems are exploited as well as its classifications, techniques, links, metrics and models. Finally the Conclusion presents the main points that can be explored in future researches.

Change Requests

In order to continue to make progress in software measurement, as it pertains to reliability and maintainability, there must be a shift in emphasis from design and code metrics to metrics that characterize the risk of making requirements changes. By doing so, the quality of delivered software can be improved because defects related to problems in requirements specifications will be identified early in the life cycle. An approach is described for identifying requirements change risk factors as predictors of reliability and maintainability problems. This approach can be generalized to other applications with numerical results that would vary according to application. An example is provided that consists of 24 space shuttle change requests, 19 risk factors, and the associated failures and software metrics.

The Cost

Requirements change management (RCM) is actually an inevitable task that might be considered in system development's life cycle, since user requirements are continuously evolving (some are added, others are modified or deleted). A large majority of studies have examined the issue of change, while most of them focused on the design and source code, requirements were often forgotten, even though, the cost of fixing the defect and introduced error due to the requirements is less higher compared to the cost of error in design and implementation. For this purpose, this work focuses on change issues in the requirements engineering (RE) context, which contains the complete initial specification. Properties such as adaptability, perception, and cooperation of the multi-agent system (MAS) allow managing changing requirements in a controlled manner. The main objective of this work is to develop an agent-oriented approach which will be effective in the requirements management to be adapted to changes in their environments.
