Regulations
Business Context
Organizations can reduce equipment failures through additional inspections, preventive replacement, monitoring, lubrication, calibration, and servicing. Applying these measures extensively across all assets, however, can produce maintenance costs greater than the operational risk they eliminate.
Automotive TRIZ Resolution
Automotive TRIZ concentrates preventive resources according to failure consequence, degradation mechanism, and detectable condition. High-criticality assets receive stronger prevention while low-risk equipment can use simpler strategies or controlled run-to-failure approaches where appropriate.
Applicable TRIZ Principles
Principle 3 – Local Quality differentiates maintenance intensity according to equipment risk.
Principle 15 – Dynamics changes intervention frequency as asset condition evolves.
Principle 23 – Feedback uses actual equipment condition to trigger preventive action.
Expected Outcome
Fewer critical equipment failures
Lower unnecessary maintenance expenditure
Better allocation of maintenance resources
Improved lifecycle cost
Decision Indicators
Early indicators that this contradiction is limiting maintenance include:
Preventive costs increase without corresponding reliability gains.
Low-criticality equipment receives extensive preventive servicing.
Components are routinely replaced with substantial remaining life.
Maintenance resources are distributed mainly by schedule rather than risk.
High maintenance spending coexists with recurring critical failures.
Monitoring these indicators helps determine where prevention should be concentrated according to operational value.
