Testing Depth vs Program Schedule
Select tests by risk-based information value and merge compatible objectives so verification coverage grows without proportional schedule impact.

Business Context
Extensive testing can expose interface problems, software defects, environmental sensitivities, and unexpected system interactions before launch. However, deeper test programs require additional time, facilities, personnel, hardware cycles, and analysis. Programs under schedule pressure may reduce testing, increasing the probability that important problems remain undiscovered.
Space TRIZ Resolution
Testing should maximize information gained rather than simply increase the number of test activities. Risk-based test selection, combined tests, automated testing, digital models, hardware-in-the-loop environments, and continuous software verification can increase coverage without proportional schedule growth.
Applicable TRIZ Principles
Principle 5 – Merging combines compatible test objectives within integrated activities.
Principle 10 – Prior Action moves testing earlier to prevent late discovery of defects.
Principle 23 – Feedback uses test results continuously to redirect effort toward remaining uncertainty.
Expected Outcome
Greater defect detection
Shorter test cycles
Reduced late-stage rework
Better verification efficiency
Decision Indicators
Early indicators include:
Test duration increases without equivalent growth in useful findings.
Similar test objectives are repeated independently.
Major defects are discovered only during final integration.
Testing is compressed primarily at the end of the schedule.
Test plans do not change despite evidence that particular areas present greater risk.
