What is the purpose of the Requirement Traceability Matrix?

Project managers can establish and monitor the progress of a project with the aid of the Requirements Traceability Matrix (RTM), a tool or document. By providing a digital thread for each demand from the start to finish of the project, it aids in the monitoring of delivery. This ensures that the project’s deliverables and scope are consistent with its baseline.

  • The Traceability Matrix is utilised at various stages of the project life cycle, including
  • The process known as requirements analysis and specification
  • Phase of Design Analysis and Specification
  • Phase of Risk Analysis
  • Unit testing, source code analysis, and integration testing
  • System testing and functional testing are phases of validation.

Traceability is used in the quality and compliance management systems of businesses that produce software, hardware, or video games, including those in the aerospace, automotive, healthcare, gaming, information & technology, and others.

It makes sure that the deliverables are free of errors while gauging how well initiatives adhere to the needs of the business or the stakeholders.

RTM is also applicable to both conventional (waterfall) and contemporary (agile) project management approaches. Sequential tracing and verification of requirements is helpful in the conventional waterfall technique. Between the sprint backlog and the product backlog, user stories are recorded using the SCRUM technique.

The elements of a requirement traceability matrix (RTM) are constructed in accordance with corporate rules and requirements, although they often contain a requirement ID, a bug ID, and test cases. Among the common components are;

Each project requirement is given a Requirement ID or Requirement Number, which is listed in numerical order.

  • Requirement Type: Classifying or grouping business needs according to function
  • Description of the Requirement – A succinct explanation of the Requirement
  • Unit Reference and identification number for test cases
  • Reference and identification number for integration test cases
  • Reference / Identification number for system test cases
  • Acceptance by users Reference and identification number for test cases
  • Test scripts for the actual testing procedure should be produced using the trace to test script method.

Implications of a traceability matrix for requirements:

An RTM makes sure that projects accomplish all of their goals. This step-by-step procedure aids in identifying the items and requirements needed for a successful test. It also aids in choosing the project’s course and timetable.

In the beginning, it will assist in identifying all requirements in a work product. Then, it will make sure that all needs are covered throughout the duration of the project.

The RTM will display the requirements coverage in terms of the quantity of test cases, the state of the design, and the progress of the execution. Additionally, it will display the UAT status for a particular test case. Your team will be able to examine changes in requirements and make knowledgeable product development decisions on the spot if you have all this information at your fingertips.

Additionally, because traceability connects artefacts from different stages of the development lifecycle, it enables teams to find and fix problems early on. Additionally, it helps lessen the stress of an audit. Additionally, if you are audited, having an RTM will make it simpler to show that you have complied with requirements, allowing you to avoid any additional costs or delays that the audit might entail.

Even a compliance matrix can be used to track needs from compliance standards. This will make it easier for you to comprehend what has to be tested and developed before the work is complete.

In a nutshell, a requirements traceability matrix facilitates goal attainment and project management.
