What is CMMS? The Complete Definition

CMMS stands for Computerized Maintenance Management System. It is software that centralizes maintenance information into a single database and provides a structured framework for planning, executing, and tracking all maintenance activities.

Think of a CMMS as the central nervous system for your maintenance operations. It digitizes and integrates every critical area of maintenance management: from work order creation to asset tracking, preventive maintenance scheduling to inventory control.

In practical terms: A CMMS replaces spreadsheets, paper work orders, and manual tracking with an automated system that ensures the right maintenance gets done at the right time, with the right parts, by the right technician.

Modern CMMS platforms go beyond basic maintenance tracking. They integrate with technologies like artificial intelligence (AI), machine learning, and the Internet of Things (IoT) to enable predictive maintenance, real-time monitoring, and data-driven decision making.

How Does a CMMS Work?

A CMMS organizes maintenance data into interconnected modules, creating a single source of truth for all maintenance activities.

Single source of truth for all maintenance data

Work Orders

Create, assign, track, and complete maintenance tasks with full audit trails.

Asset Register

Complete equipment records including specs, location, history, and documentation.

PM Schedules

Automated preventive maintenance scheduling based on time, usage, or conditions.

Inventory

Track spare parts, set reorder points, and link parts to specific assets.

Labor Management

Track technician availability, skills, certifications, and work hours.

Reports & Analytics

KPI dashboards, trend analysis, and customizable reports for data-driven decisions.

8 Essential CMMS Features

1. Work Order Management

The heart of any CMMS. Work order management digitizes the entire lifecycle of a maintenance task, from creation and assignment to tracking and completion.

Key Capabilities

  • Create work orders from requests, PMs, or detected issues
  • Assign based on technician availability and skills
  • Track status: open, in progress, on hold, completed
