Greater Equipment Reliability vs Lower Spare-Parts Inventory
Classify spare parts by criticality and lead time, using shared regional inventories and predictive-maintenance data to minimise capital tied up while protecting time-sensitive operations.

Business Context
Agricultural equipment failures can interrupt time-sensitive planting, spraying, harvesting, irrigation, feeding, and handling activities. Maintaining spare components on site can reduce recovery time, particularly where suppliers or service centers are distant. However, extensive spare-parts inventories tie up capital, require storage, and may contain components that become obsolete without ever being used.
Agriculture TRIZ Resolution
Spare-parts strategies should differentiate components according to failure probability, consequence, lead time, and substitutability. Critical inexpensive parts with long replenishment times can remain locally available, while expensive or rarely required components can be shared, supplied through service agreements, or positioned regionally. Predictive maintenance can further reduce uncertainty by identifying deteriorating components before immediate replacement becomes necessary.
Applicable TRIZ Principles
Principle 1 – Segmentation classifies spare parts according to criticality and replenishment requirements.
Principle 24 – Intermediary uses dealers, cooperatives, service networks, or shared inventories for less frequently required components.
Principle 23 – Feedback uses equipment-condition information to anticipate component demand.
Expected Outcome
Faster recovery from critical failures
Lower spare-parts investment
Reduced obsolete inventory
Improved equipment availability
Decision Indicators
Early indicators include:
Large inventories contain parts that are rarely or never used.
Critical failures cause long delays because specific components are unavailable.
Spare-parts policies do not distinguish between critical and noncritical items.
Similar farms independently hold identical expensive backup components.
Parts are ordered only after condition deterioration becomes a failure.
These indicators support differentiated inventory and shared support strategies.
