test responsibility matrix:
      it is the mapping between testing types and 
developments stages. at what stage what type of testing 
occurs.


requirement tracebility matrix:
                   this is just like a check list, this is 
mainly used for revewing the test case document, to check 
that the test cases covered all the functionalities or not.


if i am wrong please send the correct answer.

trm(test responsibility matrix) defines the mapping b/w 
test factors/quality factors to the development stages. 
generally test/quqlity factors are
1)authorisation
2)access control
3)ease of use
4)ease of operation
5)continuity
6)correctness
7)coupling
8)data integrity
9)performance
10)recovery
11)portable
12)sevice level
13)maintainble
14)methodology
15)audit trail
Depending on type of project,scope of project n size of 
project we r going to select the quqlity factors from the 
above mentioned factors.

coming to rtm(requirement tracability matrix),it defines 
the mapping b/w test cases and use cases.
test case is a set of steps documented along with the i/ps& 
expected results for testing a low level requirement.
use case is a document which consists of the information 
about the individual raquirement.

hi guys!!!!!1

I respect  all your answers but , i think all of u got
confused about word 'matrix' here TRM is not used for
mapping purpose instead its used to assign different levels
for testing with group of people or a particular, and keep
track of that. no doubt that its table like structure but
main field mentioned with stages of action and columns r
specified with respective performance levels like P=
perform, A=assigned and approved,R = review, I=Input etc

RTM :
     A very identyfing testcase should be traced by to one 
and more requirements and hence RTM's are prepared by Test 
Engg to show the mapping B/w the given requirements and the 
test case identified.
RTM's are mainly used by the TestLead to perform the 
TestDesign coverage analysis

sory guyz i dont know properly abt TRM
