What is Spare Parts Management?

June 9 Phillip Slater

Spare parts inventory management is the process of making decisions about the stocking, control, and use of spare parts that support physical assets and equipment.

Its objective is to balance operational risk, service requirements, and inventory investment.

Why Spare Parts Are Different
Unlike retail inventory:
* Demand is often irregular.
* Demand can be extremely low.
* Consequences of stockouts can be severe.
* Lead times can be long.
* Obsolescence risk can be significant.

These characteristics mean that traditional inventory techniques are often unreliable when applied directly to spare parts.

Core Decisions
What to stock
How much to stock
Where to stock
