Technology Integration Speed vs Interface Stability
Formalise interface change-control procedures within the software lifecycle framework to enable technology refresh without triggering full system re-qualification.

Regulations
Business Context
Rapid integration of new sensors, processors, communications systems, software, and payload technologies can keep space platforms technically relevant. However, frequent changes to interfaces can propagate modifications through multiple subsystems and undermine configuration stability. Freezing interfaces protects integration but can prevent adoption of valuable technologies.
Space TRIZ Resolution
Stable interface contracts should be maintained while adaptable translation layers absorb technology-specific differences. Mechanical adapters, software abstraction layers, configurable electrical interfaces, and standardized data services can allow underlying technologies to evolve without forcing changes throughout the spacecraft architecture.
Applicable TRIZ Principles
Principle 1 – Segmentation separates stable system interfaces from changing technology implementations.
Principle 24 – Intermediary uses adapters and abstraction layers between evolving components.
Principle 35 – Parameter Changes adjusts interface characteristics within controlled boundaries.
Expected Outcome
Faster technology integration
Greater interface stability
Reduced redesign propagation
Improved platform longevity
Decision Indicators
Early indicators include:
Component upgrades require changes across several unrelated subsystems.
Interfaces are frozen so rigidly that improved technologies cannot be integrated.
Technology-specific assumptions are embedded throughout the architecture.
Minor supplier changes trigger major integration effort.
Adapter or abstraction mechanisms are absent.
