on using tacebillity maatrix

The coverage of testcases can be decided through 
Tracebility Matrix with which we can explain the process of 
through requirements of the users. Generally the 
tracebility matrix may include the following:

1. User Requirements
2. Reviews statements (SRS)
3. Scenarios (Test Conditions)
4. Test Stratagey
5. Test Technique
6. Test Sumarry Report

          If any doubts pls free contact me my id is 
dsrinivas1982@gmail.com and pls send question to me also so 
that I can enrich my knowledge on testing concepts.

By using tracibility matrix we will decide whether are 
requirements are covered or not .

In tracibility matrix we will have:
a)REq id :
b)Testcases id.
Here we will map the requiremnts to the testcases & ensure 
that all requirements are covered.

by using RTM(requrment tracibility matrix)we can decide all 
the test cases r coverd r not

 this is to check wether all the functanalites r coverd r 
not.
1.sr.no
2.reqirments ID.
3.Description
4.unit testcase ID
5.System testcase ID
6.impact analysis
7.bidirectional impact  

 for based on this we can do regration testing
