CMMS Software for Manufacturing
Preventive plans, meters, and requests against the same machines that run your jobs, plus a straight account of what is still missing.
A computerized maintenance management system runs maintenance work: an asset register, preventive schedules triggered by date or meter reading, maintenance work orders assigned to technicians, spare parts, and the repair history behind each machine. EAM is broader, covering the whole asset lifecycle across sites.
Machine maintenance tracked against the resources that run the work.
A CMMS exists because machines fail on their own schedule and the plant needs a plan that does not depend on one person's memory. The core of it is an asset register, preventive plans triggered by a date or a meter reading, a way for the floor to report a problem, and the history that tells you whether a machine is getting worse. WorkCell holds part of that. Machines are already resources the routings and the scheduler use, they carry meters with a full reading history, preventive plans come due on a calendar or a meter interval, and operators raise maintenance requests a supervisor approves or rejects. An approved request becomes work with tasks against it, assigned to a technician, with the parts it consumed issued from the same inventory the shop buys from. Because the machine is one record, the maintenance history and the production history it interrupted sit side by side.
Plants where equipment condition limits output, and maintenance today lives in a wall calendar, a technician's notebook, or an hour meter somebody reads on a good week.
The interval is known to the person who has run the machine for fifteen years. When they are out, or gone, the service is late, and afterwards nobody can establish whether it was ever performed at all.
A plan triggered at five hundred running hours is only as good as the reading behind it. Readings taken irregularly and chalked on the machine make the trigger approximate and the history useless for deciding anything.
An operator mentions that the spindle sounds wrong. There is no record, no priority, no decision, and no way afterwards to show that the failure was called out three weeks before it stopped the line.
The planner schedules the bottleneck solid and maintenance needs four hours on it. Whoever argues harder wins, the service slips, and the unplanned outage that follows costs several times what the window would have.
Deciding whether to rebuild or replace needs the record of what has already been done to the asset. Kept on paper, that record is organised per person rather than per machine, and it leaves when they do. The capital request then gets argued from impressions, on a machine the plant has owned for twenty years.
Machines are already resources
The asset you maintain is the same record the routings and the scheduler use, with its asset number, manufacturer, model, capacity, and rates. There is no second equipment list to keep in step with the first.
Meters with a full reading history
A resource can carry meters, counter or gauge, in hours, cycles, pieces, or your own unit. Every reading is kept with who took it, when, the delta, and resets flagged rather than quietly overwriting the running total.
Preventive plans on a calendar or a meter interval
A plan triggers on an interval in days or on a meter interval, and carries a lead time, an estimated duration, and a next-due date. What is coming becomes visible before it is late.
Task lists with measurements and safety steps
A plan holds ordered tasks. A task can require a measurement with upper and lower limits in a unit of measure, and can be marked a safety step, so lockout is part of the procedure rather than a reminder.
Maintenance requests from the floor, with approval
An operator reports a problem against the resource with a priority and a downtime flag. A supervisor approves or rejects it with a reason, so the triage decision is recorded and not only made in a corridor.
Overdue reporting
Plans past due are listed by how far past due they are, so the first question in a maintenance meeting has an answer that came from the system instead of from the person who kept the calendar. A plan that has drifted a hundred days past due stops being invisible, which is usually the whole value of the first month.
MES runs production on the machine: operations, quantities, operators. A CMMS runs work on the machine itself: preventive plans, repairs, parts, condition history. They share the asset record and little else, which is why bolting one onto the other usually produces two equipment lists.
CMMS vs ERPThe ERP owns money and material; a CMMS owns equipment condition. The overlap is spare parts, which are inventory with a maintenance purpose. Running both on one database is how a repair's parts and hours reach cost without anyone keying them twice.
CMMS vs OEEOEE measures the loss, a CMMS tries to prevent it. Availability is the term maintenance actually moves, so OEE is usually how a preventive program gets judged. A maintenance calendar with no measurement behind it becomes a calendar nobody trusts.
CMMS vs APSThe scheduler and the maintenance plan compete for the same machine. A preventive task with a due date is capacity that disappears, and a plan the scheduler cannot see gets skipped because the machine was busy. One resource record, two kinds of demand.

Is WorkCell a CMMS?
Partly, and not yet fully. Preventive plans, meters with reading history, task lists with measurement limits, maintenance requests with approval, and overdue reporting all exist. Maintenance execution does not: there is no maintenance work order, no technician assignment, and no spare parts management. Evaluate it on exactly that.
What is the difference between a CMMS and an EAM?
Scope. A CMMS manages maintenance work on equipment you already own: plans, requests, repairs, parts, history. An EAM manages the whole asset lifecycle, including capital planning, acquisition, depreciation, and disposal, usually across many sites. Most discrete manufacturers under a thousand people need the CMMS half.
Can preventive maintenance trigger off machine hours instead of dates?
Yes. A plan can trigger on a meter interval rather than a calendar interval, against a counter in hours, cycles, or pieces on that resource. Readings are entered at the terminal or posted straight to the resource over the API, so a PLC gateway or an MTConnect adapter can keep the counter current without anybody writing a number on a clipboard.
Does maintenance show up in the production schedule?
Not yet. Plans carry a next-due date and an estimated duration, and a shift exception can take a resource out of capacity, but a due preventive plan does not automatically reserve time in the schedule. Today a planner has to place that window deliberately.
Where do spare parts live?
In the same inventory the shop buys production material from, which is the point. A bearing is an item with a stocking policy and a supplier behind it, a parts list attaches to the preventive plan that will consume it, and the issue is posted against the maintenance work that used it. That means a repair carries its true cost and the planning run sees MRO demand alongside everything else rather than discovering it when the crib is empty.
Should we buy a standalone CMMS alongside WorkCell?
If maintenance execution and spare parts are central to how you run, yes, and keep one asset list by exporting WorkCell's resources into it. If you mainly need preventive intervals visible and floor problems reported and triaged, what is here may be enough for now.
One system instead of a standalone CMMS.
