Which of the four standard verification methods involves operating the system and observing its behavior without formal measurement?
Answer: Demonstration
Demonstration involves operating the system to show it can perform a required function, using observation rather than formal measurement to confirm compliance.
What is the purpose of a Verification Cross-Reference Matrix (VCRM)?
Answer: To map each requirement to its planned verification method, level, event, and success criteria
A VCRM maps every requirement to its verification method, the level at which it will be verified, the verification event, and the success criteria for compliance.
Why is it important to plan verification methods during requirements definition rather than during the test phase?
Answer: Early planning ensures requirements are written to be verifiable and that verification resources, facilities, and schedules are adequately planned
Planning verification during requirements definition ensures requirements are verifiable as written and that adequate resources, facilities, and schedule are allocated for verification activities.
What distinguishes system-level verification from component-level verification?
Answer: System-level verification evaluates the complete integrated system against system requirements; component-level verification evaluates individual components against their allocated specifications
System-level verification evaluates the complete integrated system against system-level requirements, while component-level verification evaluates individual components against their specifications.
What is a test procedure and what must it include to be effective?
Answer: A step-by-step document specifying prerequisites, setup, execution steps, expected results, pass/fail criteria, and data recording requirements
An effective test procedure provides step-by-step instructions with prerequisites, setup, execution steps, expected results, pass/fail criteria, and data recording requirements.
How does model-based verification complement traditional testing?
Answer: It enables verification of conditions difficult to test physically, supports early verification before hardware exists, and reduces the number of physical test cases needed
Model-based verification complements testing by verifying conditions impractical to test physically, enabling early verification before hardware availability, and optimizing test programs.
