On r/assetmanagement, a simple question sparked an in-depth exchange between maintenance professionals: can a CMMS fail to reduce reactive maintenance? The first reply, from u/InigoMontoya313, gets straight to the point: "A CMMS is not a guaranteed solution for reducing reactive maintenance, and anyone who claims otherwise is talking nonsense. A CMMS doesn't create a proactive maintenance culture, doesn't provide the resources to be proactive, or the right management methodologies. All of that comes from elsewhere." (The comments quoted below were written in English; we quote them from our French article, so the wording may differ slightly from the originals — see the thread for the exact text.)
This is not an isolated view. It is the common thread of the whole discussion, carried by people who live industrial maintenance day to day — including, rare and valuable, a salesperson from a CMMS vendor who confirms the diagnosis from the other side of the counter.
The permanent-firefighter trap
The most striking line in the thread comes from u/MYK_Maintenance, and it alone sums up why so many teams buy software without ever escaping corrective maintenance: "The trap is that you're too busy putting out fires to build the things that would stop the fires from starting." A team that spends its days repairing breakdowns never, by definition, has time to stop and analyse why those breakdowns keep coming back. The software may well exist, but as long as nobody has the capacity to use it for anything other than documenting the day's emergency, nothing changes structurally.
Alerting is not acting
A second commenter, u/GovTechVeteran, points to a distinction many managers forget when buying software: "Being alerted that a machine needs maintenance and actually doing the work are two different things — and the CMMS can't be held responsible for failure if the resources to respond to the alert aren't there. Whether it's a lack of staff or of materials, that lack of resources will make a good CMMS fail every time. Proactive maintenance is still the work of people, not the system."
This point is often overlooked in CMMS sales pitches: the software can schedule, notify and keep a history. It cannot send someone to do the job in place of the team. A third, shorter comment makes the same point: u/Conrad_noble sums up the root cause in a single line — "Understaffing, or poor resource management."
The real problem, which even a CMMS vendor admits
The most instructive comment in the thread comes from an unexpected quarter: u/eWorkOrders-CMMS, who openly says they work on the CMMS vendor side. Their candour deserves to be quoted in full: "I should say I'm on the vendor side, so take this with a pinch of salt — but I've heard this a lot, and most of the time it isn't the software that's the problem. One thing that doesn't get talked about enough is scheduling. Teams load all their preventive maintenance into the system, but they never block out the time to actually do it. PMs end up competing for the same hours as everything else, and breakdowns win every time. On paper everyone looks busy because lots of work orders are getting closed, but PM compliance quietly slides. A few months later the same machines start breaking down again, and everyone wonders why they're still firefighting."
A software vendor publicly admitting that the software usually isn't the problem is a rare and honest signal. It matches exactly what we argue in our articles on choosing a trade-specific tool: a good tool makes good practice possible; it does not replace it.
On paper, everyone looks busy. The real test is not the number of work orders closed; it is whether the same machines are still breaking down three months later.

View the demoHow to steal a little capacity without stopping everything
The most useful part of u/MYK_Maintenance's comment is the practical method he suggests for breaking the cycle, without pretending it will be easy: "You have to steal a bit of capacity, even when it hurts. What usually works: start logging everything, even the reactive stuff. Every breakdown — what failed, which machine, how long it took. Do that for a month and patterns usually show up — often a handful of machines responsible for most of your emergencies. Those become your first preventive maintenance targets. Fixing the worst ones frees up time, which frees up more time. It compounds, slowly. It's also worth tracking reactive versus planned as a percentage, so you can actually see whether it's moving. Hard to improve a number you're not looking at."
This advice does not depend on any particular software — but it becomes much easier to follow when logging each job, even an urgent one, does not mean re-keying it from a notebook in the evening. That is exactly what we cover in our article on field service management: the record filled in on site, not reconstructed from memory hours later.
A tool such as Rotor-FSM does not replace the discipline described in this thread — stealing time, logging systematically, targeting the worst offenders. What it changes is the cost of that discipline: logging a breakdown from the field in a few seconds, rather than hoping to remember it at the end of the day.
Once the culture shift is under way, the practical mechanics are described in building the periodic inspection calendar.
Why isn't a CMMS enough to reduce corrective maintenance?
Because software can flag that a machine needs servicing, but it cannot do the work in place of the team. If nobody has time to deal with the alerts, the CMMS documents corrective work better; it does not reduce it.
How do you break out of a purely corrective maintenance cycle?
Start by systematically logging every breakdown, even in an emergency: which machine, what failed, how long it took. After a few weeks, recurring patterns emerge, and those are what you need to tackle first to free up time.
What is the real sign that a maintenance team is improving?
Not the number of work orders closed, but how the ratio between planned and reactive maintenance changes over time. A high number of closed orders can hide preventive maintenance that is never actually carried out.
Does Rotor-FSM help break this cycle?
Rotor-FSM makes it easier to log every job, reactive ones included, directly from the field, so that tracking does not depend on re-keying everything in the evening. It is a necessary condition for spotting recurring patterns, not a magic fix for a lack of resources.
No software replaces the difficult, deliberate decision to steal time from emergencies in order to build what will stop them happening again. But a tool that makes logging trivial rather than tedious at least removes one excuse for not getting started.
