Requirements coverage is a measure used in project management and software development to ensure that all specified requirements are addressed in the final product. It helps teams identify which requirements have been implemented, which are still pending, and whether any have been overlooked. This process is crucial for maintaining quality and meeting stakeholder expectations. By analyzing requirements coverage, teams can create test cases that align with each requirement, ensuring thorough validation of the product. This practice not only enhances the quality of the final deliverable but also minimizes the risk of defects and increases customer satisfaction.
