Frequent Health Checks vs Mission Productivity
Shift to condition-based diagnostics that exploit operational telemetry so health checks consume resources only when degradation evidence justifies them.

Business Context
Frequent diagnostic tests and health checks can detect degradation before it develops into serious failures. However, these activities may consume power, communications time, processing capacity, mechanism cycles, or payload availability. Excessive checking can therefore reduce the productive time of otherwise healthy spacecraft.
Space TRIZ Resolution
Health monitoring should become condition-based rather than purely periodic. Passive telemetry, trend analysis, embedded diagnostics, and event-driven testing can determine when deeper checks are justified. Diagnostic activities can also be combined with normal spacecraft operations whenever the same data can serve both purposes.
Applicable TRIZ Principles
Principle 6 – Universality uses operational data simultaneously for mission activity and health assessment.
Principle 19 – Periodic Action performs dedicated checks only at appropriate intervals or conditions.
Principle 23 – Feedback increases diagnostic intensity when evidence of degradation appears.
Expected Outcome
Strong equipment health awareness
Higher mission productivity
Reduced unnecessary diagnostic activity
Earlier detection of meaningful degradation
Decision Indicators
Early indicators include:
Routine health checks consume significant operational time.
Diagnostic frequency remains fixed despite stable equipment performance.
Equipment cycles are consumed primarily by testing.
Normal telemetry contains useful diagnostic information that is not exploited.
Payload operations are frequently interrupted for precautionary checks.
