RTM (Requirement Traceability Matrix)

What is a Traceability Matrix?

The focus of any testing engagement is and should be maximum test coverage
By coverage, it simply means that we need to test everything there is to be tested.
The aim of any testing project should be 100% test coverage

RTM Prerequisites

• We need to know exactly what is it that needs to be tracked or traced
• Test cases based on some input documents – Business requirements document, Functional Specifications document and Technical design document (optional) etc...

Common Artifacts Used for Requirements and System Design

• BRD – Business Requirement Document
• BR Log – Business Requirement Log
• DSRS – Detailed Software Requirement Specification
• DSTD – Detailed Technical Design Document 
• CTD – Change Tracking Document 
• CR Log – Change Request Log 

Create RTM

• Test Case Design / Test Case writing 
• Tracking test cases to the requirement documents through a table with reference numbers for each requirement
• Each test case is linked to a particular agreed requirement ,validated assumption ,constraint or dependency
