| 4.4.11-6-1 Ensure reliability engineering analyses demonstrate design life and mean mission duration requirements are satisfied |
Phase B |
Phase C |
Phase D1 |
|
Ensure worst-case analyses, component stress levels, failure mode and effects critical analysis and reliability analyses support mission life. Ensure independent risk assessment performed of all identified single point failures. Evaluate electrical and mechanical worst case design for boxes/components. Ensure preliminary results reported at Preliminary Design Review, and updated/final results reported at Critical Design Review.
