What is Traceability Matrix?
A traceability matrix is a document that presents the technical requirements for a given test scenario and its current state. It helps the testing team understand the level of testing that is done for a given product.
The traceability process itself is used to review the test cases that were defined for any requirement. It helps users identify which requirements produced the most number of defects during a testing cycle.
Not only does this show areas in need of improvement, but it also helps mitigate future roadblocks and identify process weaknesses.
