CMMS · the basics

What is a CMMS?

In brief

A CMMS (computerised maintenance management system, GMAO in French) is software that centralises the tracking of an equipment fleet: a record per machine, hour meters, upcoming servicing, anomalies reported from the field, and a full history. It replaces scattered Excel files and paper logbooks that get lost. It becomes useful as soon as a fleet has several machines tracked by several people.

You keep hearing “CMMS” without really knowing what it is. Here is a simple explanation, no jargon, written for a fleet manager or a small business owner.

CMMS: what does the acronym mean?

CMMS stands for computerised maintenance management system; in French it is GMAO (Gestion de Maintenance Assistée par Ordinateur). Behind this slightly technical name, the idea is simple: instead of tracking your equipment's maintenance on loose sheets of paper, text messages or Excel files scattered across several computers, everything is brought together in a single piece of software, accessible to the whole team.

In practice, a CMMS keeps, for each machine, its specifications, its running hours, its most recent jobs, its upcoming deadlines (servicing, statutory inspection) and the issues reported by operators or mechanics.

What does it actually do for an equipment fleet?

For a fleet of mini excavators, aerial work platforms, telehandlers or other construction equipment, a CMMS is primarily there to make sure nothing is forgotten and nothing is lost. Each machine has its own record: make, model, serial number, location or site assignment, hour meter, maintenance history.

The mechanic or fleet manager sees at a glance what needs doing this week, what is overdue, and what has already been done. An operator who spots an issue in the field can report it directly, with a photo if needed, without waiting to run into someone back at the depot.

  • A record per machine with its full history
  • Servicing and inspection deadlines visible in advance
  • Anomalies reported from the field, with photo and severity level
  • A job schedule with technicians to assign
  • A digital maintenance logbook, accessible at any time

Preventive maintenance and corrective maintenance: the difference

A CMMS distinguishes two ways of maintaining a machine. Corrective maintenance means stepping in after a breakdown: the machine stops, you repair it. Preventive maintenance means stepping in beforehand, on a defined schedule (number of hours, date), to reduce the risk of breakdown and premature wear.

The goal of a CMMS is to help shift from corrective (reacting) to preventive (anticipating), by scheduling servicing and sending an alert as a deadline approaches, rather than relying on everyone's memory.

When do you actually need a CMMS?

With a single machine and a single person in charge, a simple logbook or spreadsheet is often enough. The need for a CMMS usually appears once several factors add up: several machines to track, several people working on them (operators, mechanics, site managers), machines spread across different sites, or statutory inspections (VGP, for example) that must not be missed.

The most common trigger: someone says “I don't know where we stand” on a machine, or an important deadline is discovered too late, once the problem has already happened.

What to look for when choosing a CMMS

Not all CMMS platforms are equally suited to field use. A few points to check before choosing.

CriterionWhy it matters
Mobile appOperators and mechanics work in the field, not in an office
Offline operationSites don't always have a network; data must sync later
Ease of useA complicated tool won't be used day to day by the whole team
Migrating existing dataBeing able to start from your current Excel file or fleet without re-entering everything
Reliable alertsBeing warned before the deadline, not after

What a CMMS does not do

A CMMS organises tracking and scheduling. It does not carry out statutory inspections (such as VGP) itself and does not replace the inspection body. Nor does it transfer the employer's responsibility for equipment safety: it simply helps avoid missing deadlines and keeps a record of what has been done.

How day-to-day rollout works

Setting up a CMMS does not mean starting from scratch. The first step is to bring in the data that already exists: the list of machines, any Excel file, the dates of known previous servicing. A good vendor offers support for this migration, without forcing the team to re-enter everything by hand.

Each machine then gets its digital record, with the deadlines already known and the desired alert rules. The field team (operators, mechanics) needs to be trained on the basics, especially reporting an anomaly from the mobile app, which is often the most used feature day to day.

The fleet manager, in turn, gets into the habit of checking the deadline schedule and reported anomalies, rather than waiting for a machine to break down before paying attention. It is this change in habits, more than the tool itself, that makes the difference over time.

Frequently asked questions

What does CMMS actually mean?

CMMS stands for computerised maintenance management system (GMAO in French). It is software that centralises the maintenance tracking of a fleet of machines or equipment: records, history, deadlines, anomalies.

Is a CMMS only for large companies?

No. Simple versions exist for small organisations. The need appears as soon as a fleet has several machines tracked by several people, whatever the size of the company.

What's the difference between a CMMS and Excel?

An Excel spreadsheet can be enough for a very small fleet and a single person. A CMMS adds automatic alerts, mobile access, a reliable history shared across the whole team, and the ability to attach photos.

Do I need a CMMS for a small fleet of 2 or 3 machines?

Not necessarily. If one person manages everything and tracking stays simple, a well-kept spreadsheet can be enough, at least to start. Switching to a CMMS makes sense once tracking becomes hard to keep up to date.

Does a CMMS replace the paper maintenance logbook?

It replaces it in digital form: every job, every inspection and every anomaly is recorded and accessible at any time, machine by machine.
