Technology Refresh Rate vs Architecture Stability
Isolate rapidly evolving technology layers behind stable interfaces so component refreshes require only incremental re-verification rather than full system safety re-assessment.

Business Context
Processors, sensors, communications equipment, software, and other digital technologies can evolve much faster than the spacecraft platforms that use them. Frequent technology refresh can improve performance and prevent obsolescence, but continual component changes can destabilize interfaces, verification baselines, supply chains, and system configurations.
Space TRIZ Resolution
Spacecraft architectures should distinguish between long-lived foundational elements and technology layers expected to evolve rapidly. Stable interfaces and modular technology zones can allow selected components to be refreshed without altering the entire system. Technology updates can then follow controlled cycles based on measurable mission value rather than every available improvement.
Applicable TRIZ Principles
Principle 1 – Segmentation separates long-lived architecture from rapidly evolving technology layers.
Principle 15 – Dynamics permits selected elements to evolve while the core architecture remains stable.
Principle 24 – Intermediary uses standardized interfaces between technology generations and stable platform functions.
Expected Outcome
Faster adoption of useful technologies
Greater architectural stability
Reduced redesign effort
Lower technology-obsolescence risk
Decision Indicators
Early indicators include:
Individual component changes trigger extensive system redesign.
Technology is frozen years before launch despite rapid market evolution.
Interfaces depend strongly on specific component generations.
Frequent technology changes repeatedly invalidate verification evidence.
Platforms become obsolete before their structural or operational life is exhausted.
