In other words, it is a document that maps and traces user requirement with test cases. It makes sure that each requirement is tested thoroughly. It means tracing the code from requirements and viceversa throughout a software development life cycle sdlc. Requirement traceability matrix or rtm captures all requirements proposed by the client or software development team and their traceability in a single document delivered at the conclusion of the lifecycle. Bidirectional traceability is the ability to trace both forward and backward i. A bidirectional traceability matrix can be manually created and maintained, or may be a byproduct of a requirements management tool. Bidirectional requirements traceability by linda westfall.

Requirements management and the traceability matrix. Integrated software testing tools like parasoft complete the verification and validation of requirements by providing an automated bidirectional traceability to the executable test case, which includes the pass or fail result and traces down to the source code that implements the requirement. It is used to ensure whether the current product remains on the right track. When the requirements are managed well, traceability can be established from the source requirement to its lower level requirements and from the lower level requirements back to their source.
