OPERATING SUPPLIES & RELIABILITY
Maintenance, Repair and Operating Supplies (MRO)
Maintenance, repair and operating supplies support the functioning of equipment and facilities. Examples can include replacement parts and consumables used to maintain operations rather than items intended as the product sold to the customer.
MAINTENANCE, REPAIR AND OPERATING SUPPLIES IN PRACTICE
- Identify the roleLink the item to the equipment or activity.
- Set the stock policyConsider criticality, lead time and demand.
- Control consumptionRecord use, replenishment and condition.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A small spare can protect a large operating flow.
A warehouse relies on a replacement part for its only suitable handling asset. It evaluates failure impact and replenishment time rather than deciding the stock level from the part’s purchase price alone.
