Maintenance Bill of Materials (BOM)
The structured parts list associated with an asset or a planned maintenance job.
Definition
A maintenance Bill of Materials (BOM) is a structured list of every part, consumable, and sub-assembly associated with an asset or a planned maintenance job. It is the connective tissue between inventory and work execution.
Asset BOM vs job BOM
Asset BOM: everything that could ever be replaced on the asset — from motors to bearings to fasteners. Used for parts identification, warranty tracking, and spare-parts planning.
Job BOM: only the parts needed for a specific work order or PM task. Used for kitting, picking, and cost accounting.
Why BOMs matter
Without a BOM, technicians waste time identifying parts, storerooms over-order "just in case," and job costing becomes guesswork. A clean BOM lets you kit jobs in advance, cut MTTR, and plan stock around actual demand.
Maintenance BOMs in FacilityLane
Each asset in FacilityLane has a linked BOM with cross-referenced inventory items. PM templates and repeat work orders inherit the right job BOM so stock checks and reorders happen before the technician shows up.
FAQ
Common questions about Maintenance Bill of Materials (BOM).
Not immediately. Start with critical and recurring-repair assets. Low-criticality run-to-failure assets usually don't repay the effort.
