Traceability Matrix:
Traceability matrix used to Map requirements to test cases.
Basically Traceability matrix ia two types:
1. Vertical Traceability matrix.
2. Horizontal Traceability matrix.
Vertical Traceability matrix is high level document which
map the requirements to all phases of the Software
development cycle.
I.e. Unit testing, Component Integration testing, System
Integration testing, Smoke/Sanity testing, System Testing,
Acceptance testing...etc.

2. Horizontal Traceability matrix.
It is related to testing related.
Traceability matrix used to:
1. Coverage analysis,
When a requirement changed it will used to identify the
Test cases prepared on that requirement.
Once the test case identified it will be very easy to
update the test case according to new requirement.
As a basic Rule of thumb:
Each requirement should have at least one test case. By
seeing the traceability matrix one can easily analyze the
no. of test cases prepared for each requirement.
If there is no test case ID's found against one
requirement that means ,test case is missing for that
requirement.
Without Traceability matrix it is very difficult to
estimate the test coverage and Change Management.
