| 4.4.11-5-1 Ensure a complete system to subsystem to unit requirement verification plan is adequately developed and documented for the subsystem to support an overall system verification |
Phase A |
Phase B |
Phase C |
|
Ensure verification plan addresses requirements verification to include units, assemblies, sub-assemblies and parts. Track evidence of analysis and test in the system and unit specifications, and require specification verification matrices to document where the requirements are verified. Ensure preliminary Independent Verification and Validation, and Integration and Test plan is ready at Preliminary Design Review and completed by Critical Design Review. Ensure any special test equipment is described at Preliminary Design Review and provided by Critical Design Review. Ensure verification plan reflects the intent of the Mission Assurance Standards.

| 4.4.11-5-2 Ensure the verification method is appropriate, adequate and documented |
Phase B |
Phase C |
Phase D1 |
|
Ensure any verification by similarity is justified and documented by Preliminary Design Review, updated at Critical Design Review. Ensure that subsystem/major component verification addresses all requirements and requirements satisfied at a lower level are accounted for in the requirement verification documentation. Ensure unit level testing conforms to required standards testing. Ensure Test-like-you-fly process is implemented and like-you-fly tests are allocated to the unit/component level as appropriate.

Phase A |
Phase B |
Phase C |
Phase D1 |
|
Ensure that access to shared facilities (e.g. radiation, acoustics, thermal vacuum) that requires advance planning is considered. Ensure that a loading assessment for an appropriate number of internal shared equipment, such as test beds and engineering units to accommodate the baseline schedule, including multiple items/space vehicles in flow is considered. Some special test equipment may have long acquisition lead times.
