Quick Answer

Preventive maintenance, often called PPM (planned preventive maintenance), is scheduled inspection and servicing of assets before they fail. Inspection software schedules recurring checks per asset, tracks completion, and links findings to the asset record.

What is preventive maintenance (PPM)?

Preventive maintenance is work performed on a schedule to keep assets reliable: HVAC filters, lift inspections, fire panels, pumps, and production lines. PPM contrasts with reactive maintenance that starts only after breakdown or complaint.

ISO 41001 and client FM contracts increasingly expect documented PPM completion rates, not only logbooks in the plant room. Digital PPM ties each visit to an asset ID and evidence.

How PPM works in practice

An FM team schedules monthly lift contractor checks and weekly in-house plant rounds. Each task appears on the technician app with the asset location and checklist. Missed visits escalate to the regional manager before client SLA breach.

Manufacturing links PPM to downtime planning: spare parts ordered from inspection trends, not emergency calls. Healthcare estates use PPM for biomedical and fire systems with audit samples by asset serial number.

Time-based, usage-based, and condition-based PPM

Preventive maintenance is not a single method but a family of scheduling models. Time-based maintenance runs on the calendar: a task is due every month or every year regardless of how hard the asset has worked, which suits statutory checks and slow-wearing equipment. Usage-based maintenance triggers on a meter instead, such as running hours, cycles, or distance, so a pump serviced every 2,000 hours is maintained in proportion to the work it actually does.

Condition-based maintenance goes a step further and acts on the asset's measured state, such as vibration, temperature, or oil analysis, so work happens only when readings show it is needed. Each model trades effort against risk differently. Time-based is simple but can over-service; usage-based and condition-based reduce waste but need reliable data. Most real programmes blend all three, matching the model to the criticality and failure pattern of each asset.

How Inspectly360 handles preventive maintenance

Inspectly360 scheduling assigns recurring inspections by asset, site, and role. Completion feeds analytics and compliance risk scores when rounds slip. Findings can raise corrective actions without leaving the asset history.

Frequently Asked Questions

What is the difference between PPM and reactive maintenance?

Reactive maintenance responds after failure: complaints, leaks, or stopped production. PPM inspects and services on a calendar or meter-based schedule to reduce failures. Inspection software makes PPM visible: which assets are due, which visits slipped, and which findings repeat. FM leaders shift budget from emergency callouts to planned rounds when completion rates improve. The financial argument is straightforward: a planned filter change or belt inspection is cheap and predictable, while the same asset failing unplanned brings a callout premium, downtime, and often a client complaint. Once a programme can prove its PPM completion rate, it becomes possible to show that rising planned coverage is what drove emergency callouts down, rather than treating maintenance as an unavoidable cost.

How does PPM relate to ISO 41001?

ISO 41001 guides facilities management systems. Documented maintenance planning and performance evidence support certification and client tenders. Digital PPM logs show planned versus completed work by asset, which strengthens ISO 41001 audits compared with scattered spreadsheets. The standard is less interested in whether a logbook exists and more in whether the organisation can demonstrate a managed system: planned work, evidence it happened, and action when it did not. A digital record that ties each visit to an asset, shows the completion rate over time, and links findings to corrective actions gives an assessor exactly that picture, and it doubles as strong evidence in a client tender where FM performance has to be proven rather than asserted.

Can one app run both PPM schedules and ad-hoc inspections?

Yes. The same platform should assign recurring PPM tasks and allow one-off snag or incident inspections without duplicate apps. Asset records aggregate both types so history is complete for handover and resale due diligence. This matters because splitting scheduled and reactive work across separate tools is how asset history gets fragmented, and a fragmented history is worth little at handover or sale. When both the monthly pump check and the emergency repair after a leak attach to the same asset record, anyone reviewing that asset sees the full story, and a technician arriving for the next planned visit already knows what failed last time and what was done about it.

What happens when a PPM visit is missed?

Good systems escalate: notify the technician and manager, increase compliance risk score for the site, and optionally block month-end reporting until critical PPM is cleared. Clients on SLAs want visibility before breach, not explanation after. The key is that a missed statutory or safety-critical visit should never be something a manager discovers weeks later in a report, because by then the SLA may already be breached and the risk carried in the meantime. By raising the site's risk score and alerting the right people the moment a due date passes, the system turns a silent gap into a visible task, and the manager can redeploy a technician or book a contractor before the client ever notices.

How do contractors fit into digital PPM programmes?

External lift, fire, and HVAC contractors complete the same digital checklist or a limited contractor role with evidence upload. The asset owner retains the master schedule and audit trail instead of receiving PDF certificates only. The difference this makes is control: when a specialist contractor works inside the same system, their visit, findings, and photos land against the asset in real time, and the FM team can see the moment a statutory check is done or overdue. Compared with waiting for an emailed certificate that may arrive late and reveals nothing about what was actually found, a shared checklist keeps the building owner in charge of the schedule and the evidence.
