It's a mapping between requirements and test cases..

TM is table to trace the project requirements

hi all
tracebelity matrix is nothing bu , checking the previous 
assignment , inorder to improve the productivity .

Hai all....
       IT KEEPS TRACK OF REQUIREMENT THROUGHOUT THE PHASES 
OF SOFTWARE DEVELOPMENT LIFE CYCLE WHEREBY IT IS EASIER TO 
FINED THE DIFECT EARLY IN THE LIFE LIFE CYCLE & LESS COST 
TO CORRECT THE DIFECT & DEFECT RATIO IS ALSO REDUSE BECAUSE 
OF THE TRACEABILITY MATRIX.


Ok...
by...

Mapping Requirements to Test Cases is called Traceability 
Matrix

Once the writting of testcase is completed,the test 
engineer will send the testcase for testlead to verify...
now the testlead will prepare Tracebelity Matrix to veriy 
wheather all the requriments are covered or not by mapping 
the requriments with the testcases available...so he can 
easily find if any of the testcase is missing for 
particular requriment.

Correct Me if iam wrong

In software Testing, the Traceability Matrix can be a 
document to trace the connectivity/integration/dependency 
between the Requirements->Test scenarios->TestCases-
>TestResults.

Its a document to trace the completes of the Testing 
process as per the requirements.

Traceability checks whether all the requirements are 
covered in the Test cases.

Hi all
TM is a document which contains a Table of linking information and used for tracing back for the reference in any kind of questionable or confusion situations.
