RTM is document that links requirements throughout the validation process. The main purpose of RTM is which is test case is missing that missing use case recover through RTM.
Requirement gathering is the 1st step in SDLC, these requirements completed by team.
After that difficult for the team to know about current status of requirements. The time to check a RTM.
What is the Purpose of Requirement Traceability Matrix?
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.
This matrix makes sure that we have covered each requirement for the product development and that each requirement is thoroughly being tested. So basically, this matrix maps all the requirements to the corresponding test cases.
RTM usually helps to evaluate the impact of project requirements. When requirements shift in the middle of a project, a traceability matrix lets you see the impacted workflows, test cases, training materials, software code, etc.
A traceability matrix can help in the effort to provide proper and consistent documentation for your team.
1.Forward traceability is used to map the requirements to the test cases. Not only will this establish that every requirement is being tested from top to bottom, but it will also assist in confirming that a project’s trajectory is sound.
2.You can make a backward traceability matrix by mapping test cases with the requirements. Doing so aids you in avoiding “scope creep” and going beyond the initial requirements unnecessarily.
3.Bidirectional traceability essentially combines forward and backward traceability into one document. This type is useful because it establishes that each requirement has relating test cases.
To create an effective traceability matrix, project managers must keep certain things in mind, starting from defining the project goals and mentioning all the project’s essential aspects.
The first step is to ensure that the project goals are accurately defined. To outline these objectives, managers must first comprehend the client’s expectations and business needs. The next step is to gather all the relevant project information and break down the goals into milestones.
The second step is to gather all of the available requirement documents that will help you build an effective traceability matrix. E.g., Business Requirement Document (BRD), Functional Requirement Document (FSD), Technical Requirement Document (TSD) that is prepared by the QA team, which includes all the test cases/scenarios.
consolidated the necessary information, you may design the template for your matrix. The Requirements Traceability Matrix has no set structure; instead, it may be tailored to the project’s needs & type.
Moreover, RTM can also be built and maintained with the use of an automated tool, Excel spreadsheet, or MS Word table.
Now, the final step is to take all the requirements through the testing process.
The information mentioned above is a brief overview of the requirement traceability matrix.
