What is the difference between a 'repairable spare' and a 'consumable spare' in maintenance inventory?
Answer: A repairable spare is rebuilt and returned to stock after failure; a consumable spare is discarded after use
Repairable spares (e.g., motors, gearboxes) are sent out for repair or rebuilt in-house and returned to inventory, while consumables (e.g., filters, belts) are used once and discarded.
How does a Computerized Maintenance Management System (CMMS) improve spare parts management compared to manual tracking?
Answer: It provides real-time inventory visibility, automates reorder alerts, tracks usage history, and links parts to equipment and work orders
CMMS integration provides accurate, real-time inventory data, usage trends for reorder optimization, and direct links between parts, assets, and work orders that manual systems cannot match.
What is 'carrying cost' of inventory and what components does it typically include?
Answer: The annual cost of holding inventory, including capital cost, storage space, insurance, obsolescence, and deterioration
Carrying cost, typically 20–30% of inventory value annually, encompasses the cost of capital tied up in parts, plus storage, insurance, taxes, obsolescence risk, and spoilage.
Which approach helps maintenance planners ensure parts are available before a scheduled work order is released to the field?
Answer: Parts kitting—pre-staging all required parts and materials for a job before the technician starts
Kitting pre-stages all parts, tools, and materials for a specific work order so technicians have everything needed at job start, reducing delays and improving wrench time.
When should a maintenance organization consider using a consignment inventory agreement with a supplier?
Answer: When carrying high-value, slow-moving parts whose stockout risk justifies availability but whose cost makes ownership expensive until consumed
Consignment is ideal for expensive, low-turnover parts because the supplier retains ownership and the facility only pays when parts are consumed, reducing capital tied up in inventory.
What is the primary risk of an overly low spare parts inventory policy (minimizing stock aggressively) in a manufacturing plant?
Answer: Extended equipment downtime when a critical part fails and is unavailable, resulting in lost production that exceeds any inventory savings
Aggressive inventory minimization saves carrying costs but increases stockout risk; when critical parts are unavailable, the resulting production loss typically far exceeds the savings from reduced inventory.
