Traceability matrix is the mapping between the requirements 
and Test cases.
Traceability matrix contains Requirement id, Test cases ids 
and number of   testcases passed and failed.

Test Lead will prepare this Traceability matrix.

With the help of Traceability matrix we know wether the 
testcases are completed or not

Traceability Matrix Useful in following real-time situation

     1. Decide the number of testcases is enough to test 
given module.
     2. To Review the testcases

Traceability Matrix is a guiding and valuable document for 
testing.

Hai Santhosh you have given good answer for that. Can u pls 
send Tracebility Matrix template with example in that.

You can please mail me to dshashibhushan@yahoo.com

a)	Trace ability matrix is nothing but to cross 
verification all requirements and test cases
b)	That is all the requirements covered by with the 
test cases
c)	Ok team lead or senior tester prepares it also.
d)	With the help of trace ability matrix covered all 
the customers requirements.
e)	It is must and should use the all-testing team.

Tracebility matrix is nothing but mapping the requirements 
to the test cases. that means in order to the client that 
we have covered all the req according to the SRS document.

there are 5 status

1. New

2. Open

3. Assign

4. Reopen

5. Differed

6. Close

Athilakshmi ur answer is confusing.
U r talking about bug i think not abt Tracebility 
Matrix.Check again and post correct answer

I understood that Tracebility Matrix is used to verify
whether all the Test cases has been covered with respect to
a application or a module which is under test.
 
Ok my question what ll be exact contents of this matrix.

That is by using this matrix how we are able to say whether
enough test cases to this module are met?

test cases contain all those tcid, expected result and
actual result, steps followed, inputs and so on...

So what does this T.Matrix contain to verify the test cases
written is enough or not..

And also how does it look, is it just a document or why it
the name Matrix...

Please anyone answer this question... I got this question in
APC interview

Tracebility matrix is the mapping between requirements and 
the written test cases.
it is used to find that all the test cases are covered or 
not and all the requirements are covered or not

TM is a document to map the requirement id with the 
testcase id ...
 > it hepls to check whether all the requirement are 
covered 
>  this document is mianly used for regression testing

Hi Santhosh Thank you for the clear answer and explanation
about traceability matrix and I do have small request.Can
you please send a template of it to my e-mail id
kiranmai_cs@yahoo.com.
Thank you

I guess you people got confused between Traceability matrix 
and Requirment Traceability matrix. 
Traceability matrix : This shows the at what stage the 
modules in the application are standing. They will be able 
to know till what stage Requirment has under gone.
They will be able to know wether the Req has gone through 
the following stages 
1.SRS, 2.SRAS, 3.HLD, 4.LLD, 5.Coding, 6.Testing.
    The answers given above says Requirment Traceability 
matrix.

Tracebility matrix is made to map wheather the testcases 
covered all prespecified functionalities or not.

the content of a traceability matrix is as follows-:
1-frs no
2-item
3-descripton
4-TCID
5-Document Name
6-Executed By
7-Date
8-Status
9-Bug Id.
