Traceability Matrix

[manisha123]

Hi,

I want some information abt what is Traceability Matrix.
And how it is usefull in s/w testing.
And how to maintain it(if possible with example)

Thanks!!!

Trace ability Matrix is a Testing estimation method

Here we compare the test cases with the requirements to ensure that all the requirements have been covered in a particular Test Phase


Sample Trace ability Matrix

A trace ability matrix is a report from the requirements database or repository. The examples show trace ability between user and system requirements. User requirement identifiers begin with "U" and system requirements with "S." Tracing S12 to its source makes it clear this requirement is erroneous: it must be eliminated, rewritten, or the trace ability corrected.

Continuation of last reply............................



ID USER REQUIREMENTS FORWARD RRACEABILITY
U2 Users shall process retirement claims S10, S11, S12
U3 Users shall process Survivor claims S13




ID FUNCTIONAL REQUIREMETNS BACKWARD TRACE ABILITY
S10 The system shall accept requirement data U2
S11 The system shall calculate the amount of retirement U2
S12 Thesystem shall calculate Point-to-point travel time U2
S13 The system shall calculate survivor annuity U3

created a matrix in a table and copied and pasted here but here it shows differently

Traceability matrix is a matrix that consists of SOS (scope of service) numbers which map to each requirement of the users, the FD's which cover these information and the short description of that information, the BA that is working on that requirement etc.

This is a mapping document that maps the requirements with the functional specs which cover that requirements, used to make sure that all the requirements will covered be covered in the final product.

Test conditions should be able to be linked back to their sources in the test basis - this is called traceability.

This matrix defines the mapping between customer requirements and prepared testcases by testers.

This is used by testing team to verify how far the testcases prepared have covered the requirements of the functionalities to be tested.

A set of test cases that passed oK earlier has started to have serious problems. Traceability between the tests and the requirement being tested enables the functions or features affected to be identified more easily.

Delivering a new release, we want to know whether or not we have tested all of the specified requirements in the requirements specification can be easily verified help of Traceability matrix.
