Requirements Traceability Matrix (RTM) and its Example Template
A Requirements Traceability Matrix (RTM) is a document that shows the relationship between different types of software requirements, such as business, functional, system, and test requirements. It provides a structured means to verify that each requirement has been addressed in the final product and helps in ensuring traceability throughout the software development life cycle (SDLC).
Why is Requirements Traceability Matrix important?
Ensures Complete Coverage: The RTM ensures that every requirement is considered during the testing phase, thus preventing any crucial requirements from being overlooked.
Documentation and Transparency: The matrix offers a clear trace of how each requirement has been addressed throughout the development process, ensuring transparency and accountability for each requirement's implementation.
Helps in Root Cause Analysis: In case of defects or issues, the RTM helps developers to find the root cause by tracking requirements from initial conception through testing and implementation.
RTM Example Template
The structure of an RTM is quite straightforward:
Requirement ID
Parent Requirement ID
Test Case ID
Test Result
REQ-001
BUS-001
TEST-001
Pass
REQ-002
SYS-002
TEST-002
Fail
REQ-003
FUN-004
TEST-003
Not Executed

In summary, a Requirements Traceability Matrix (RTM) is an essential document in software development that helps maintain traceability between different requirements and ensures complete coverage during the testing phase. By providing a clear line of sight into the relationships between various types of requirements, the RTM simplifies the process of root cause analysis when issues arise and fosters transparency throughout the entire SDLC.
