Why traceability matrix is used

To ensure this, the traceability matrix and tests are essential. Traceability is the process of reviewing all defined test cases for any requirement. Traceability allows one to determine which requirements generated the most defects during the testing process.

The traceability matrix is, essentially, a tool that helps to ensure that the purpose, requirements and results of the project remain in line with what was initially agreed.

The requirements traceability matrix provides an accurate connection between requirements, test instances and defects. Quality control can be achieved when the final product is tested for unexpected scenarios with minimal defects and all functional and non-functional requirements are met. From that moment on, quality improvement can also be achieved.

The benefits of utilizing a traceability matrix are many, here are the most important ones:. To effectively run tests with the help of the traceability matrix, it is important to follow four basic rules:. In case of modifications suggested by stakeholders or users, they must be promptly reported to the project team.

It also manages the overall project requirements. This method is straightforward and can be easily done by anyone. There are many kinds of RTMs.

For example, a test matrix is used to prove that tests were conducted. It can also be used to identify issues and requirements during the development of software. An RTM ensures that projects do everything they set out to do. This step-by-step process helps identify the requirements and the products that are required to be tested successfully.

It also helps in determining the project's direction and timeline. First, it will support the identification of all requirements in a work product. The RTM will show the requirements coverage in terms of the number of test cases, design status, and execution status. It will also show the UAT status for a specific test case.

With all this information at your fingertips, your team will be able to analyze changes in requirements and make informed product development decisions on the fly. And because traceability links artifacts across the development lifecycle, it helps teams identify and resolve issues before they become problems.

It can also help avoid the pressure of an audit. And if you do get audited, having an RTM will make it easier to demonstrate that you have complied with regulations which means you can avoid additional expenses or delays the audit may cause. You can even use it to track requirements from compliance regulations in a compliance matrix. That will help you understand what you need to test and develop before the work is finalized.

In more complicated systems, the traceability matrix may include references to additional documentation, including user requirements, risk assessments, etc. The traceability matrix can be created and maintained in an automated tool , in an Excel spreadsheet, or MS Word table.

Q: Are traceability matrices required by the FDA and other regulatory bodies? A: The United States Code of Federal Regulations does not specifically require a traceability matrix, but creating a traceability matrix is recognized as a validation best practice.

Q: How does Ofni Systems create their traceability matrices? A: We use an automated traceability matrix utility to ensure requirement traceability and generate the actual requirement traceability document.

Other organizations might use Excel spreadsheets to keep a table of requirements, despite this being extremely difficult to maintain manually. Contact us and ask us your question.
