Data Integration vs System Independence
Business ContextIntegrated information improves coordination across engineering, procurement, construction, operations, and maintenance. Excessive dependence between platforms, however, can make local systems vulnerable to failures or changes elsewhere.
Brown Field Industrial Projects TRIZ ResolutionIntegrate information through controlled interfaces while preserving functional autonomy. Common data models, APIs, synchronization layers, and local fallback capability allow information sharing without requiring every system to operate as one tightly coupled platform.
Applicable TRIZ Principles
Principle 24 – Intermediary: connects systems through controlled integration layers.
Principle 1 – Segmentation: preserves independent functional boundaries.
Principle 11 – Beforehand Cushioning: maintains fallback capability when shared services are unavailable.
Expected Outcome
Better information integration
Greater system independence
Reduced cascading failures
Easier technology change
Decision IndicatorsEarly indicators that this contradiction is limiting project performance include:
Failure of one platform interrupts unrelated functions.
Systems duplicate data because integration is difficult.
Small interface changes require modifications across many applications.
Local functions cannot operate when central services are unavailable.
Integration architecture creates growing technical dependencies.
Monitoring these indicators helps organizations share information without creating unnecessary system coupling.
