CMMS vs EAM
CMMS centralizes maintenance operations. EAM covers the full asset lifecycle. Here’s how to tell which one you need.
Definition
A CMMS (Computerized Maintenance Management System) focuses on day-to-day maintenance — work orders and preventive maintenance. An EAM (Enterprise Asset Management) system extends to the full asset lifecycle, including procurement, depreciation, reliability engineering, and capital planning.
Scope comparison
CMMS: work orders, PM schedules, parts inventory, technician mobile, basic analytics. Primary users are maintenance managers, planners, and technicians.
EAM: everything in a CMMS plus asset registry with financial depreciation, capital planning, reliability engineering (RCM/FMEA), lifecycle cost tracking, procurement, and multi-site rollups. Primary users expand to reliability engineers, finance, and executive leadership.
When CMMS is enough
Smaller operations, single sites, or teams whose primary need is execution (work orders out, PMs completed, parts on hand) can run entirely on a CMMS. Adding EAM before you need it adds configuration overhead without payoff.
When you need EAM
You need EAM when capital decisions (repair vs. replace, lifecycle cost) matter at the executive level, when reliability engineering is a discipline (RCM, FMEA, failure coding), or when asset finance (depreciation, book value) needs to stay in sync with operational reality.
How FacilityLane covers both
FacilityLane is an AI-native platform that covers CMMS operations and the broader EAM lifecycle on a shared asset hierarchy. Start on the CMMS workflows you need today; add EAM capabilities as the organization matures.
FAQ
Common questions about CMMS vs EAM.
Yes — provided your CMMS exposes its asset, work order, and PM history. FacilityLane includes migration tooling to preserve history when moving between tiers.
