![]() ![]() There are different types of traceability matrix: In case a requirement is met by a specific procedure, there may a column to indicate reference of the procedure and the dedicated version number.A column for the criticality of the specific requirements, in order to plan a level of testing that is proportional to the level of criticality of the requirement.A section dedicated to change control number, to ensure full traceability after a modification is implemented.A section to include a brief description of the specific requirements.Link between Requirements, Design Elements (Functional and Design Specifications) and Testing Activities.The Requirements Traceability Matrix may contain: Obviously, not all the items mentioned below are mandatory, thus it is responsibility of the organization of have a Requirements Traceability Matrix which is functional to the organization. The following items shall be included in a Requirements Traceability Matrix. In this latter case, a full requirement traceability matrix shall be documented. Lastly, for custom applications, full traceability within all the levels of the lifecycle, from requirements to verification activities shall be documented. However, for software applications of Category 4 (Configured), it might be necessary to have traceability between user requirements, configuration and verification activities. For example, for non-configurable software systems, traceability between user requirements and verification tests may be sufficient. The level of traceability shall be different based on the category of software, if we take in consideration the GAMP-5 categories. The Requirement Traceability Matrix is not a specific requirement clearly mentioned by the FDA or other regulators however, in the FDA guidance related to software validation, it is clearly mentioned that “Software validation includes confirmation of conformance to all software specifications and confirmation that all software requirements are traceable to the system specifications”. This requirement is typically covered with the covered through the Requirement Traceability matrix. The standard and probably the most straightforward method is the so-called Requirements Traceability Matrix. There are different ways to achieve traceability, including specific tools. ![]() ![]() All the requirements are verified and traced to the related verification activities that demonstrate that the specific requirements have been met.Īs for other elements related to software validation, the rigor of the traceability activity shall be based on risk, complexity and novelty associated to the computer system under validation.Ensure that all the requirements are met and can be traced to the appropriate configuration or design elements.In the framework of software validation, it is of fundamental importance to maintain full traceability during the whole entire project and in this context the requirement traceability matrix is the right tool to achieve this goal. Your Defects that are filed (created) are linked to the Test Executions in which they were found.Requirements traceability matrix Traceability for Software Validation Activities Your Tests are scheduled in a Test Cycle and are Executed properly. Your Requirements are linked to your Tests. To get accurate and useful traceability reports, ensure that the following criteria are met during testing (from test creation to test execution): They can also be used as customer delivery reports highlighting how every one of their requirements has been met, tested and is defect-free.Īnother very important reason to run Defect to Requirement traceability reports is to get a better sense of how many defects are holding up the requirements and more importantly, which defect(s) is impacting the most number of requirements – thereby allowing for better bug-fixing prioritization. Traceability reports can also be tremendously useful in producing end-of-release audit reports for compliance and regulatory reasons. Also, keeping track of how many open defects exist for requirements help make a Go/No-Go decision regarding the readiness of the software to be shipped. Once the software has been built, keeping track of which test executions have passed for a particular requirement allows the team to make a quality statement about these requirements. For example, starting with requirements, knowing how many of them have tests written for them is useful in the early stages to ensure there is appropriate test coverage. In fact, it can have a special meaning at various phases in that release cycle. The ability to trace linkages from requirements all the way to defects or vice versa is particularly useful in a software release cycle. ![]()
