Traceability Matrix
A traceability matrix is a document or tool used in software development and project management to map and track relationships between requirements, design elements, tests, and other project artifacts. It ensures that all requirements are covered by tests and that changes are properly managed throughout the development lifecycle. This matrix helps maintain alignment between project objectives and deliverables, facilitating verification and validation processes.
Developers should use a traceability matrix in regulated industries (e.g., medical, aerospace, automotive) or complex projects where compliance, quality assurance, and risk management are critical. It is essential for demonstrating that all requirements are tested and met, aiding in audits, debugging, and change impact analysis. This tool helps prevent scope creep and ensures that software meets stakeholder needs and regulatory standards.
