PPM (Planned Preventive Maintenance) is a time-based maintenance strategy that schedules recurring inspections and tasks to prevent equipment failures, reduce unplanned downtime, and extend asset life. It’s executed through checklists, calendars, and a CMMS to ensure repeatable, auditable work.

What Is Planned Preventive Maintenance (PPM)?

Planned preventive maintenance (PPM) is a maintenance strategy where equipment servicing, inspections, and repairs are scheduled in advance at fixed time intervals to prevent unexpected equipment failures, reduce downtime, and extend asset lifespan.

Key statistics & why they matter

Unplanned downtime is a major line item for manufacturers, recent industry analyses estimate that manufacturers lose approximately $50 billion per year.
Preventive maintenance can cut equipment downtime by up to ~45% and materially extend asset life.
Predictive approaches can improve on preventive savings, roughly 8–12% better than preventive and as much as 40% better than reactive strategies in cost reduction metrics.
Planned Maintenance Percentage (PMP) benchmarks vary by industry; leading practitioners target very high planned work, industry sources suggest benchmarks from ~80% up to 85%+ for world-class operations.
The systemic cost of downtime is large and rising: large studies put total downtime costs for top firms into the hundreds of billions (and trillions across global enterprises).

Why PPM matters

Reduces emergency repairs and overtime labour (lower total cost of ownership).
Increases uptime, production output, and asset lifespan.
Creates audit trails and compliance records that protect warranties and meet regulatory requirements.

15 PPM Essentials Every Facilities Manager Needs to Know

1. What PPM actually means

Quick answer: PPM = scheduled, recurring maintenance tasks performed to prevent failures (inspections, lubrication, filter changes, calibrations).
Why it matters: Clear definitions improve communication across operations, reliability, and procurement teams; it prevents “maintenance by rumour.”
Action: Add a 1-line definition to your SOPs and open every maintenance meeting by reciting it.

2. PPM vs Predictive vs Reactive (short comparison table)

Quick answer: PPM = scheduled time-based; Predictive = condition-driven (sensors/analysis); Reactive = repair after failure.
Why it matters: Pick the strategy that matches your maturity and budget: start with solid PPM, then layer predictive when you can justify sensor and analytics investments.
Action: Map each asset into A/B/C tiers: A = candidate for predictive later; B = PPM only; C = reactive acceptable.

3. Top 10 PPM tasks every plant should standardise

Quick answer: Visual inspection, lubrication, belt/tension check, filter change, safety checks, fastener torque, electrical terminal check, calibration, leak check, and cleaning.
Why it matters: Standardised tasks reduce variability and make labour estimates accurate.
Action: Create one-page checklists for each asset type and deploy them in your CMMS.

PPM Task	Frequency	Why It Matters	Action
Visual inspection	Daily/Weekly	Identifies obvious wear, leaks, or safety hazards early.	Log observations in CMMS; flag anomalies immediately.
Lubrication	Weekly/Monthly	Reduces friction and wear, extending equipment life.	Apply correct lubricant; update CMMS log.
Belt/tension check	Monthly	Prevents slippage, breakdowns, and efficiency loss.	Adjust tension; replace worn belts; record in CMMS.
Filter change	Monthly/Quarterly	Ensures proper airflow/fluid flow and reduces contamination.	Replace filters as per schedule; log completion.
Safety checks	Daily/Weekly	Protects personnel and prevents accidents.	Inspect guards, emergency stops, PPE; log in CMMS.
Fastener torque check	Monthly/Quarterly	Prevents machinery loosening, vibration damage, and failure.	Torque bolts/nuts to spec; record results in CMMS.
Electrical terminal check	Quarterly	Prevents shorts, overheating, and electrical failures.	Inspect, clean, and tighten terminals; log in CMMS.
Calibration	Quarterly/Annual	Ensures instruments and sensors provide accurate readings.	Perform calibration as per manufacturer; update records.
Leak check	Weekly/Monthly	Prevents fluid/gas loss, environmental hazards, and energy waste.	Inspect seals and hoses; repair leaks; log completion.
Cleaning	Daily/Weekly	Removes dust, debris, and contaminants to maintain efficiency.	Perform cleaning of equipment surfaces; log in CMMS.

4. How to build a PPM schedule (rules of thumb)

Quick answer: Use frequency bands: daily (visual), weekly (lubrication), monthly (filters/adjustments), quarterly (minor service), annual (overhaul).
Why it matters: Consistent cadences prevent missed tasks and keep spare parts predictable.
Action: Start with manufacturer recommendations + operational history, then adjust based on failure data.

5. PPM checklist (compact, printable template)

Below is a responsive HTML checklist table you can paste into a CMS. It follows a clean structure (task, frequency, duration, owner, notes). The table is mobile-safe — it scrolls horizontally on small screens.

Task	Frequency	Est. Duration	Owner	Notes
Visual inspection (safety & leaks)	Daily	10–15 min	Technician	Log anomalies
Lubrication (bearings)	Weekly	20 min	Technician	Use specified grease
Filter replacement	Monthly	30–45 min	Technician	Stock 2 spares

6. PMP & KPIs: what to measure

Quick answer: Track Planned Maintenance Percentage (PMP), PM Compliance, MTTR, MTBF, First-Time Fix Rate, and Schedule Compliance.
Why it matters: PMP shows how much of your workload is planned vs reactive — world-class operations push PMP very high.
Action: Calculate PMP monthly and set a progressive target (e.g., move from 50% → 65% → 80% over 12 months).

7. Common PPM mistakes (and fixes)

Quick answer: Over-servicing, poorly scoped tasks, no feedback loop, and missing spare parts.
Fixes: Right-size intervals using failure data, keep concise checklists, and use CMMS to flag parts.
Action: Run a 90-day “audit & right-size” of all PMs: remove duplication, merge overlapping tasks, and add condition checks where useful.

8. PPM by domain

Quick answer: HVAC = filter & coil clean; Electrical = insulation/resistance checks; Chillers = refrigerant & oil checks.
Why it matters: Domain specificity prevents generic PMs that aren’t effective.
Action: Build domain-specific checklists and keep them under 10 steps for field tech usability.

9. Selecting PPM software

Quick answer: Must-have: scheduling, repeatable work orders, mobile execution, audit logs, asset hierarchies, spare-parts linkage.
Why it matters: Software enforces discipline, without it PPM slips back to ad-hoc.
Action: Run a 30-day pilot focused on scheduling + mobile checklists and measure PM completion rate.

How a CMMS helps: a CMMS automates reminders, enforces checklists, links tasks to asset records, and creates exportable reports for audits, all critical for scaling PPM.

Makula CMMS can help teams implement time-based PPM quickly by:

Scheduling recurring time-based work orders (daily/weekly/monthly/annual).
Delivering mobile checklists and offline completion capture for field technicians.
Generating PM completion logs and compliance reports for audits.

10. PPM cost & ROI: simple calculation

Quick answer: ROI ≈ (Downtime cost avoided + unplanned repairs avoided + extended asset life value) − PPM program cost.
Why it matters: Showing a simple ROI model gets budget approvals. Use conservative downtime reduction assumptions (start at 10–20% if you’re unsure, scale up).
Action: Build a 1-page ROI model with three scenarios (conservative, realistic, optimistic) and present to stakeholders.

11. 30-60-90 day rollout plan (fast implementation)

Quick answer: 30 days = audit assets & tasks; 60 days = import tasks into CMMS, deploy mobile checklists; 90 days = measure PM compliance and iterate.
Action: Use this timeline as a public roadmap in your weekly operations meeting.

12. How to use PMs to prepare for audits & warranties

Quick answer: Keep dated completion logs, technician signoffs, and parts used recorded in CMMS — these are your warranty and compliance evidence.
Action: Export monthly PM completion reports and store them in a centralised compliance folder.

13. When to move from PPM to predictive

Quick answer: Move after you have repeatable PMs, good failure data, and a business case for sensor/analytics ROI (and spare capacity to act on alerts).
Action: Pilot predictive on 1–3 high-value assets only; measure the delta in avoided downtime vs your PPM baseline.

14. Spare parts & inventory optimisation

Quick answer: Maintain a right-sized spare parts inventory linked to your PMs so technicians can complete PPMs on schedule and avoid parts searches that delay work.
Why it matters: PMs fail to produce uptime gains when missing parts cause work to be delayed or converted into reactive jobs. A parts policy (minimum/maximum stock, critical spares list, lead-time tracking) reduces PM failure rates, lowers expedited shipping costs, and improves first-time fix rates. Digitally linking parts to each PM task turns vague “bring parts” notes into precise pick-lists for store staff and technicians.
Action: Create a critical-spares list for the top 20 assets, map each PM task to required parts and quantities, and enable automated low-stock alerts in your CMMS (for example, a time-based CMMS like Makula can attach parts to PM templates and trigger reorder alerts).

15. Continuous improvement & PM change control

Quick answer: Treat PPMs as living documents — review PM effectiveness regularly and version changes through a simple change-control process.
Why it matters: Over time, PMs accumulate cruft (duplicate tasks, overly frequent intervals, or obsolete steps). Without a feedback loop that captures technician observations and failure outcomes, PMs drift from useful to wasteful. A lightweight CI process (capture observations, run a 90-day pilot for any change, measure impact on failure rate/PMP) preserves reliability while preventing over-servicing.
Action: Add a one-line “Technician observation” field to every PM completion form; schedule a monthly PM review meeting to triage observations; require a 90-day pilot and data sign-off before making interval or scope changes permanent.

FAQs

PPM is a time-based maintenance strategy where equipment inspections, servicing, and repairs are scheduled in advance to prevent unexpected failures, reduce downtime, and extend asset lifespan.

PPM is scheduled and time-based. Predictive maintenance uses condition monitoring and analytics to anticipate failures. Reactive maintenance occurs after a failure. PPM is the foundation; predictive is layered on high-value assets; reactive is a last resort.

PPM reduces emergency repairs and overtime, increases uptime and production, extends asset life, and provides audit trails for compliance and warranty protection.

Use frequency bands: daily (visual), weekly (lubrication), monthly (filters/adjustments), quarterly (minor service), and annual (overhaul). Start with manufacturer recommendations and operational history, then adjust based on failure data.

Common tasks include visual inspections, lubrication, belt/tension checks, filter changes, safety checks, fastener torque, electrical terminal checks, calibration, leak checks, and cleaning. Standardise and document them in your CMMS.

Track KPIs like Planned Maintenance Percentage (PMP), PM Compliance, MTTR, MTBF, First-Time Fix Rate, and Schedule Compliance. Calculate PMP monthly and progressively improve your targets.

Maintain completion logs, technician sign-offs, and parts usage records in your CMMS. Export monthly PM reports for compliance and warranty evidence.

Only after you have repeatable PPMs, reliable failure data, and a business case for sensor/analytics ROI. Start with a pilot on 1–3 high-value assets and measure benefits versus PPM baseline.

Link spare parts to each PM task in your CMMS. Maintain minimum/maximum stock levels and set automated low-stock alerts. This reduces PM delays and avoids converting planned tasks into reactive work.

Treat PMs as living documents. Review effectiveness regularly, capture technician observations, pilot changes for 90 days, and measure impact on failure rates and PMP before making changes permanent.
