Questions & Answers

Q: What is a requirements traceability matrix and why is it important?

A requirements traceability matrix is a grid that connects user requirements to the final system deliverables. It is important because it ensures that all requirements are met and provides a tool for assessing change requests and tracking them throughout the project.

Q: What information is included in a requirements traceability matrix?

A requirements traceability matrix includes a unique ID and description for each requirement, references to stakeholders, details on how the requirement fulfills a need or opportunity, and identification of the deliverables that will meet the requirement.

Q: What are the benefits of forwards traceability in a requirements traceability matrix?

Forwards traceability maps each requirement to the test cases that will demonstrate it. This ensures that each requirement has a corresponding test case, reducing the chances of scope creep and ensuring all requirements are properly validated.

Q: How can requirements traceability matrices be created?

Requirements traceability matrices can be created using software tools specifically designed for this purpose. Alternatively, basic project management software or spreadsheet software can be used to construct a simple matrix. Templates and examples are also available for reference.

Summary & Key Takeaways

• A requirements traceability matrix links stakeholders' requirements to the deliverables that will satisfy them, primarily used in software projects.

• It helps track each requirement throughout the project to ensure deliverables can meet all requirements and assess change requests.

• The matrix includes information about each requirement, such as unique ID, description, reference to stakeholders, fulfillment, and deliverables.
