Vaatimusjäljitys

Vaatimusjäljitys, known in English as requirements traceability, is the process of documenting the life of a requirement, both forwards and backwards, from its origin to its implementation and testing. It establishes a clear link between a requirement and all related artifacts, such as design documents, code, and test cases. The primary goal of vaatimusjäljitys is to ensure that all requirements are understood, implemented, and verified.

This practice is crucial in complex projects, especially in software development and engineering, where it aids in managing change, verifying completeness, and demonstrating compliance. By maintaining traceability, project teams can easily determine the impact of a change request on other parts of the system. If a requirement is modified, vaatimusjäljitys helps identify which design elements, code modules, and test cases need to be updated. Conversely, if a piece of code or a test case is being examined, traceability allows for the identification of the specific requirement it relates to.

Effective vaatimusjäljitys typically involves using specialized tools or maintaining detailed matrices that map requirements to their corresponding design specifications, code implementations, and test results. This systematic approach reduces the risk of overlooking critical requirements, ensures that the final product meets the intended objectives, and facilitates audits and regulatory compliance. It is an integral part of good project management and quality assurance practices.
