How preventive maintenance works

Preventive maintenance is how routine work gets planned before it turns into a repair. In MaintenanceOps, a PM schedule is a recurring template that creates work orders on a cadence — for example, monthly inspections, quarterly filter changes, or annual equipment service.

The simple way to think about PM

Build the recurring task once. MaintenanceOps keeps bringing the work back when it is due, while each generated work order records what happened during that individual service cycle.

The PM cycle

1. Set the schedule — define the task, cadence, due date, assets, and procedure.
2. Watch the due date — MaintenanceOps tracks when the next cycle is approaching.
3. Generate the work — the work order appears automatically inside the lead-time window, or you generate it manually.
4. Complete the maintenance — the technician performs and documents the work.
5. Move to the next cycle — the schedule advances and waits for the next due date.

For schedules that recur from completion, the next due date is based on when the current cycle was actually completed. This keeps the recurrence tied to the real maintenance history instead of an ideal date that may have slipped.

What a PM schedule controls

Setting	What it answers
Title and description	What work needs to happen?
Recurrence	How often should it happen?
First due date	When does the cycle begin?
Lead time	How early should the work appear?
Asset or assets	What equipment is being maintained?
Default assignee	Who normally receives the work?
Category	How should the work be organized and reported?
Procedure	What steps should the technician follow?
Compliance tag	Should this work be identifiable as compliance evidence?

Automatic or manual generation

Automatic generation is the normal setup. When the PM reaches its lead-time window, MaintenanceOps creates the work order without someone having to remember to do it.

You can also turn automatic generation off. A manual-only schedule still tracks when the task is due, but someone chooses when to generate the work order. Manual generation is also useful when you want to start a due cycle early.

See Creating a PM schedule for the setup options.

One schedule can cover multiple assets

A PM schedule can apply to more than one asset. This is useful when several similar pieces of equipment receive the same service on the same cadence.

When multiple assets are selected, the schedule can create either separate work orders for each asset or one combined work order covering all selected assets.

Choose based on the history you need

If you need to prove that each individual unit was serviced, separate work orders usually provide the clearest asset history. A combined work order is useful when the task is naturally performed and documented as one group.

Know what is coming due

The PM schedules page gives you List, Year, Month, and Week views. Schedules are visually organized by timing, including Overdue, Due soon, and Scheduled, with compliance work identified separately when tagged.

Your dashboard also summarizes preventive maintenance so overdue and near-term work is visible without opening the full PM schedule list.

Overdue PM needs a decision

An overdue schedule should not become background noise. Review whether the work still needs to be completed, reassigned, rescheduled, or corrected at the schedule level so the PM program reflects what the team can actually maintain.

Schedule versus generated work order

The PM schedule answers: When should this happen again?

The generated work order answers: What happened this time?

Once generated, the work order behaves like normal maintenance work. The technician can update status, follow the checklist, record labor, parts, purchases, photos, comments, and complete the job. The PM schedule remains behind it, ready for the next cycle.

Why PM records matter

Consistent PM records help you see whether planned maintenance is actually being completed, what equipment costs to maintain, and where recurring work is falling behind. When procedures and asset links are used consistently, each completed cycle also becomes part of the long-term maintenance history.
