What Is Requirement Traceability Matrix and Why Is It Needed ?
A traceability matrix is a part of software testing process and is used to track whether the requirements are met or not.
A traceability matrix is an archive that compares any two-baseline documents that require a many to-many relationship to check the fulfillment of the relationship. It is utilized to track the prerequisites and to check that the present project necessities are met.
Requirement Traceability Matrix or RTM catches all requirement proposed by the customer or development team and their traceability in a solitary report conveyed at the finish of the life-cycle.
At the end of the day, it is a document that maps and follows client requirement with the test cases. The fundamental motivation behind Requirement Traceability Matrix is to see that all test cases are secured so that no functionality ought to miss while testing.
Different Types of Traceability Matrix:
- Reverse Traceabilty Matrix:
It is utilized to guarantee whether the present product stays on the desired track. The reason behind this sort of traceability is to check that we are not extending the extent of the venture by including code, design components, test or other work that is not indicated in the prerequisites. It maps test cases to prerequisites or requirements.
- Forward Traceability:
This matrix is utilized to check whether the task advances in the wanted course and for the right kind of product. It ensures that every necessity is connected to the product and that every prerequisite is tested completely. It maps test cases and requirements together.
- Bi-directional Traceability:
This traceability matrix guarantees that all requirements are secured by test cases and test scenarios. It dissects the effect of a change in requirements influenced by the defect in a work product and the other way around.
Some of the parameters of Requirement Traceability Matrix are as follows:
- Requirement ID
- Requirement Type and Description
- Trace to design specification
Unit test cases
- Integration test cases
- System test cases
- User acceptance test cases
- Trace to test script
QA teams don’t create the BRD and TRD. Likewise some organizations use Funtion Requirement Documents (FRD) which are like Technical Requirement Document; however the procedure of developing traceability matrix continues as before.
WorkFlow of RTM:
The Matrix is bi-directional, as it tracks the requirements ahead by analyzing the yield of the deliverables and in reverse by taking a gander at the business prerequisite that was indicated for a specific component or feature of the product.
Benefits of Traceability Matrix:
- It specifies if any of the requirements are missing and inconsistencies are there in the document.
- It ensures 100% test coverage.
- It helps in investigating or assessing the effect on the QA team as for returning to or re-chipping away at the test cases.
- It depicts execution status or overall defects keeping in mind business requirements.
Vital Points About Traceability Matrix:
- On the off chance that there is a technical design document or use cases or some other ancient rarities that you might want to track you can simply expand the above created record to suit your requirements by including extra columns.
- When this “defects” section is utilized to build up the retrogressive traceability we can tell that the “New client/user” functionality is the most defective. Rather than reporting that this and this test case failed, TM gives a straightforwardness back to the business prerequisite that has most defects in this way demonstrating the Quality as far as what the client wants.
- As a further stride, you can shade code the defect ID to demonstrate to their states. For instance, defect ID in red can mean it is still Open, in green can mean it is closed. When this is done, the TM acts as a wellbeing check report showing the status of the deformities relating to a specific BRD or FSD usefulness is being open or shut.
