An Exhaustive Requirement Analysis Approach to Estimate Risk Using Requirement Defect and Execution Flow Dependency for Software Development

Requirement defects are one of the major sources of failure in any software development process as they prevent smooth operation and is taxing both in terms of tracking and validation. The objective of this article is to make requirement analysis phase exhaustive by estimating risk at requirement level using requirement defect information and execution flow dependency as early as possible to inhibit them from being incorporated in design and implementation. The proposed approach works as a two-fold process which computes risk involved with each requirement twice. The whole process is divided into a three-layered framework to finalize requirements with clear vision and scope of a project. The entire process has been supported by a software case study. The results of the proposed work are promising and will help software engineers in ensuring that all business requirements are captured correctly with clear vision and scope. It will also help in decreasing the chances of failure, risk, and conflicts between stakeholder and developer and other challenges involved to develop the project.
