Downtime is the enemy of any facilities management professional. Every minute an essential asset is offline, it costs money, disrupts operations, and can even compromise safety. The central question for every facility manager isn't if they should have a maintenance strategy, but which strategy will deliver the best return on investment.
For decades, preventive maintenance was the gold standard. Today, powered by IoT and advanced analytics, predictive maintenance is challenging the status quo. But is it the right move for everyone?
This guide will cut through the noise. We'll compare predictive and preventive maintenance, explore the pros and cons of each, and help you decide which approach, powered by the right CMMS maintenance management software, will truly optimise your asset lifecycle.
Key Takeaways
Preventive Maintenance (PM) is a scheduled, time-based strategy ideal for predictable, non-critical assets.
Predictive Maintenance (PdM) is a condition-based strategy that uses real-time data to predict failures in critical equipment.
The best approach is often a hybrid model, applying the right strategy to the right asset.
A powerful CMMS like FMClarity is essential to manage either strategy effectively and provide crucial data for compliance and reporting.
What is Preventive Maintenance? The Tried-and-True Approach
Preventive maintenance (also known as preventative maintenance) is a proactive facilities and asset management strategy based on a fixed schedule. Think of it like getting your car serviced every 10,000 kilometres, regardless of whether it's showing signs of trouble.
The pain point here is managing these countless schedules without letting anything fall through the cracks. This is where modern software is crucial. Platforms like FMClarity make this incredibly straightforward with intuitive PPM Scheduling tools that automate an entire maintenance plan, ensuring no routine check is ever missed.
Pros:
Simplicity and Predictability: PM schedules are easy to create and follow, making budgeting and resource planning straightforward.
Proven Effectiveness: It is a well-established method that demonstrably extends asset lifespan compared to a purely reactive "run-to-failure" approach.
Lower Upfront Cost: Generally, PM does not require the sophisticated sensors or data analysis tools associated with predictive models.
Cons:
Risk of Over-Maintenance: You may perform maintenance on assets that don’t need it, wasting time, labour, and the cost of perfectly good parts. Recent industry analysis from McKinsey suggests this "unnecessary maintenance" can still account for a significant portion of all maintenance activity, with some studies placing the figure as high as 30%.
Doesn't Prevent All Failures: Catastrophic failures can still occur between scheduled services, as PM doesn't account for the actual, real-time condition of an asset.
What is Predictive Maintenance (PdM)? The Data-Driven Future
Predictive maintenance is a more advanced, condition-based strategy. Instead of relying on a calendar, PdM uses technology and data analysis to predict exactly when an asset will require attention.
It involves placing sensors on critical equipment to monitor conditions like vibration and temperature. The challenge is ensuring these critical alerts don't get lost in email chains. Tools within FMClarity, like the unified Inbox, solve this by ensuring the right technician gets an instant, trackable alert, dramatically cutting down response times.
As IBM notes, "PdM happens only when it is required, which avoids the risk of over-maintenance and premature parts replacement."
Pros:
Maximum Efficiency: Maintenance is only performed when data shows it's necessary, eliminating wasted resources and minimising operational disruptions.
Increased Reliability: According to research by Deloitte, predictive maintenance can reduce equipment breakdowns by up to 70% and lower maintenance costs by 25%.
Greater Insight: PdM provides a deep understanding of your assets' health, allowing for more accurate long-term capital planning.
Cons:
Higher Initial Investment: Requires investment in sensors, connectivity (IoT), and powerful asset management software capable of handling complex data.
Complexity: Implementing a PdM program requires specialised expertise in both maintenance and data analysis.
Predictive vs. Preventive Maintenance - An Overview
Feature | Preventative Maintenance (PM) | Predictive Maintenance (PdM) |
|---|---|---|
Strategy | Time-based or usage-based schedule | Condition-based, real-time monitoring |
Cost | Lower upfront, higher long-term | Higher upfront, lower long-term |
Labour | Scheduled, potentially wasteful | As-needed, highly efficient |
Downtime | Scheduled and planned | Minimal, only when failure is likely |
Technology | Basic CMMS with PPM scheduling | Advanced CMMS, IoT sensors, analytics |
Best For | Less critical assets, predictable wear | Critical assets, complex machinery |
Which Strategy is Right for You? A Quick Checklist
Choosing between PM and PdM isn't always an all-or-nothing decision. The best approach is often a hybrid one. Use this checklist to evaluate your assets:
Your assets might be a good candidate for preventive maintenance (PM) if:
It has a predictable failure pattern.
The cost of failure is relatively low.
It is not a mission-critical piece of equipment.
Your budget for upfront technology investment is limited.
The skills for data analysis are not currently available on your team.
Your assets are likely ready for predictive maintenance (PdM) if:
Its failure would cause significant operational disruption or safety risks.
It has a complex or unpredictable failure pattern.
The cost of downtime is extremely high.
You are looking to optimise maintenance budgets and labour across your portfolio.
You are committed to leveraging technology as a core part of your facility management solutions.
The Backbone of a Modern FM Strategy: FMClarity
Whether you choose a preventive, predictive, or hybrid approach, one thing is certain: you cannot manage it effectively on a spreadsheet. This is where a comprehensive platform like FMClarity becomes the central hub for your entire maintenance operation.
FMClarity is designed to solve the biggest pain points in facilities management:
Eliminate Communication Silos: It centralises everything from the moment a problem is logged in the Request Listing to the final sign-off.
Stop Chasing Information: Stakeholders no longer have to guess the status of a job. With automatic Work Order Updates, everyone from the maintenance officer to the portfolio manager is kept informed in real-time.
Simplify Audits and Reporting: This level of tracking isn't just for efficiency. It provides a complete, auditable history for every asset, which is essential for simplifying compliance and passing regulatory audits with confidence.
This visibility is the first step towards what we at FMClarity call true Asset Lifecycle Management. Our platform turns your maintenance strategy into actionable data, giving you control over the entire journey of your assets, from procurement to disposal, ensuring you maximise value at every stage.
