IRSE L&SE - Solution independent Validation and its application to CBTC

The presentation will cover the following:

Solution Validation Checks the conformity of the process and the outcome against the requirements of various sub-systems.

Solution validation also ensures that any failed factory acceptance tests before the system closures for site testing are having proper safety justification.

This safety justifications ensure that the failed FAT tests will not cause any dynamic blocker to the system testing during the closure.

It checks the correctness, consistency and adequacy of test cases and executed tests.

This Solution independent Validation checks that developed solutions are traceable to the requirements.
