Business Context
Detailed failure analysis can identify root causes, common dependencies, propagation mechanisms, and potential mission consequences before launch. However, attempting to analyze every conceivable failure scenario with equal depth can consume substantial engineering effort and delay design decisions. Reducing analysis indiscriminately can leave critical vulnerabilities undiscovered.
Space TRIZ Resolution
Failure analysis should be driven by criticality, uncertainty, and system consequence. High-consequence functions and poorly understood interactions receive deeper analysis, while lower-risk conditions use standardized methods or existing evidence. Analysis should also begin early and evolve with architecture maturity rather than being concentrated near design completion.
Applicable TRIZ Principles
Principle 3 – Local Quality concentrates analytical depth where failure consequences or uncertainty are greatest.
Principle 10 – Prior Action performs critical failure analysis before architecture becomes difficult to change.
Principle 23 – Feedback redirects analytical effort as testing and design evidence reveal new risks.
Expected Outcome
Stronger understanding of critical failures
Faster engineering progress
Better allocation of reliability effort
Earlier elimination of major vulnerabilities
Decision Indicators
Early indicators include:
Low-consequence and mission-critical failures receive similar analytical effort.
Reliability analysis repeatedly delays design decisions.
Important failure interactions are discovered only after integration.
Analysis continues after additional detail provides little new information.
Risk findings do not influence the priority of subsequent engineering work.
