For NASA programs using risk-based independent verification and validation (IV&V), detailed NASA-developed/supported simulation of key flight phases provides deeper government insight and certification ability.
Spotlight on Lessons Learned
Shared use of a requirements management database with NASA contractors and partners greatly aids engineering collaboration and communication.
The likelihood of success increases if the group responsible for implementing design verification methods chosen early in a program’s life cycle is allowed to contribute to the selection process.
Mistake-proofing techniques built into system processes can aid in preventing human error when engineers and test operators make time-critical decisions in unique circumstances such as dangerous weather or limited supplies.
Procedures developed by the NASA community to identify, catalog, and inspect accident debris proved invaluable in the Space Shuttle Columbia accident investigation.
Independent mechanical walkdowns of spacecraft are sometimes credited with discovering discrepancies that could have interfered with mission success.
NASA’s Commercial Orbital Transportation Services (COTS) Program provides a starting point for formulation, design, management, and implementation of future public-private capability development partnerships.
Strong lines of communication between designers and analysts must be maintained to ensure fidelity of analysis results as flight component configurations evolve.
A NASA Engineering and Safety Center assessment of the Autonomous Flight Termination System resulted in coding standard and software static analysis recommendations for software development teams.
