What is the purpose of a Test Readiness Review (TRR)?
Answer: To confirm that the test article, test procedures, test environment, and support resources are ready to begin formal testing
A TRR verifies that all prerequisites for formal testing are satisfied: the test article is in its approved configuration, procedures are approved, facilities are ready, and support is in place.
What is the difference between qualification testing and acceptance testing?
Answer: Qualification testing demonstrates that the design meets requirements under worst-case conditions; acceptance testing verifies that each production unit meets specifications
Qualification testing verifies the design type meets requirements under extreme conditions; acceptance testing verifies each individual production unit meets workmanship and functional specifications.
Why is independent verification and validation (IV&V) sometimes required for critical systems?
Answer: To provide an unbiased assessment by a team independent of the development organization, reducing the risk of undetected errors and conflicts of interest
IV&V provides unbiased technical assessment by an organization independent of the developer, reducing risks of confirmation bias and conflicts of interest in critical systems.
What is the role of validation in ensuring system effectiveness?
Answer: Validation confirms that the verified system actually satisfies stakeholder needs and performs effectively in its intended operational environment
Validation confirms that the system, even if fully verified against requirements, actually meets stakeholder needs and works effectively in the real operational environment.
What is regression testing and why is it critical during system modifications?
Answer: Re-executing previously passed tests after a modification to ensure the change has not degraded existing functionality
Regression testing re-runs previously successful tests after modifications to verify that changes have not inadvertently broken existing functionality.
How do verification and validation activities support risk management?
Answer: They systematically reduce technical risk by providing objective evidence that the system meets requirements and stakeholder needs at progressively higher levels of assembly
V&V activities systematically reduce technical risk by providing objective evidence of compliance and effectiveness at each integration level, enabling informed risk decisions.
