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.
