test cases and test requirements.It is done using 
fucntional documents

Tracebility matrix is a document mainly useful for checking 
where we have listed all the requirements and used for 
mapping of test cases to each requiement.

In this document each of these requirements are assigned 
priorites.

The sample template of traciblity matix is like:

This tracibility matrix is generally prepared from 
requirement gathering face onwards, and modified once the 
testcases are ready and mapping for the req.

This document is generally preapred by PL or TL postion 
people.

Req_id : Rquirement Id
Req_Desc : Requirement Description
Priority : How much priority is for the requirement
TestContions : what are the test conditions for that req.
TestCaseId : What are the testcaseIds mapped for this req.
PhaseOfDev. : In which face is the req.(dev, unit, testing)

Two type of traceability.

1. Forward traceability
   Req. Capture -> Design Document -> Test Cases
   OR
   Req. Capture -> Test Cases
2. Reverse traceability
   Test Cases -> Design -> Req. Capture
   OR
   Test Cases -> Req. Capture

Normally Forward traveability is used.
