LSST Verification & Validation Process & MBSE Methodology

Verification Requirement – A statement that defines precisely what will be done to verify the requirement. If there is any vagueness in the requirement, the Verification Requirement should clearly address the noted issues and define what precisely will be verified and any limitations. The statement should define what will be done, where it will be done, what special test equipment (SPE) is needed, and what project hardware/software is needed.
– Success Criteria - A statement that defines the explicit pass/fail criteria. This statement should be clear enough that an independent third party observer should be able to determine if the verification event was successful or not.
