Across almost every site we work with, maintenance teams are being asked to deliver more with fewer hands, tighter budgets, and increasing pressure to keep equipment running without interruption. The result is a familiar pattern: teams end up swinging between doing work too early or reacting only once something has gone wrong.
A helpful way to look at this problem is through a simple metaphor drawn from the old tale of ‘Goldilocks and the three bears’ – one option is too hot, one too cold and one just right. Maintenance strategies often follow the same pattern of extremes…
Reactive approaches are too cold.
Heavy preventative schedules are too hot.
And somewhere in the middle lies the balance that keeps plants safe, stable, and efficient.
For many years, that middle ground was known as condition-based maintenance. But with access to real-time data, AI-driven insights, and intelligent platforms like PlantOS and MachineCloud, that ‘just right’ point has evolved.
When Maintenance Strategies Are ‘Too Cold’ or ‘Too Hot’
Reactive Maintenance: too cold
Waiting until something breaks guarantees unplanned downtime, higher safety risk, and pressure on already stretched teams. It’s efficient in the moment but rarely effective in the long-term.
Preventative Maintenance: too hot
Scheduled servicing exists for a reason, but over time it often grows in a heavy, resource-intensive program. Thousands of tasks accumulate, many with unclear value and teams simply don’t have enough time to complete them all.
In some cases, over-maintaining equipment can also introduce unnecessary risk and/or damage. Pulling machines apart too often increases the chance of installation errors, disturbance of components, or creating faults that didn’t previously exist. The result is more effort spent maintaining equipment that may have been performing perfectly fine.
Both extremes cost more in the long run, just in different ways.
Why the Goldilocks ‘Just Right’ has shifted
For many years, the balancing point of ‘just right’ was condition-based maintenance. Rather than relying on time-based schedules, condition-based maintenance responds to what the equipment is actually doing.
Condition-based maintenance is still valuable, but modern industrial environments have evolved.
Equipment loads vary constantly. Failure modes are more complex. Production demands shift rapidly. And teams have less time than ever to interpret data and decide what to do next.
In short, knowing something is wrong isn’t good enough anymore. Teams need clarity, prioritisation, and confidence.
Which brings us to the modern Goldilocks point…
The New ‘Just Right’: Prescriptive Monitoring
Prescriptive monitoring takes the foundations of condition-based maintenance and turns them into something far more actionable.
Instead of simply flagging unusual behaviour, prescriptive systems help teams understand what the issue is likely to be, how urgent it is, and what action will have the greatest impact. They provide context across the wider asset fleet, guidance on next steps, and the confidence to intervene at the right moment rather than on a timer or assumption.
It’s the evolution from ‘something looks unusual’ to ‘here’s what’s happening, what it means, and what to do about it.’
Prescriptive monitoring gives teams a clearer, more reliable middle ground that helps them avoid unnecessary work without risking delayed interventions.
Why Prescriptive Strategies Reduce Cost and Downtime
By removing ambiguity, prescriptive monitoring supports smarter decisions and more stable operations. Teams spend less time on work that isn’t needed, and more time addressing issues that genuinely matter. Unplanned breakdowns decrease because faults are detected and prioritised earlier, and shutdown preparation becomes smoother because the team has clarity on which assets require attention and when.
Over time, this approach reduces operational waste, extends equipment life, and lowers the overall cost of maintenance. Most importantly, it allows teams to act with precision instead of pressure, replacing guesswork with informed confident decision-making.
How to Move Toward a Prescriptive Maintenance Approach
Most sites don’t need a major overhaul to get started. A few practical steps can help build the foundation for a more effective prescriptive strategy.
- Establish clear visibility of your site
A strong prescriptive approach begins with understanding what’s running, where it sits, and how critical it is to safety and production. Clear asset and criticality data makes it easier to prioritise where advanced monitoring will have the most impact. - Select the assets that genuinely benefit from deeper insight
Not everything needs prescriptive monitoring. Focus on equipment that drives production stability, has complex or variable failure modes, and/or carries high downtime and quality risk. These are the assets where early detection and guided decision-making create meaningful value. - Treat condition insights as the starting point, not the end point
Prescriptive monitoring builds on your existing condition signals. Instead of stopping at ‘anomaly detected’, it interprets that information, prioritises it, and connects it to a clear recommended action. - Shift from dashboards to decision support
The goal isn’t more information. It’s guidance that fits naturally into day-to-day maintenance workflows and helps teams act confidently at the right time.
Goldilocks Maintenance for Modern Sites
The Goldilocks idea isn’t a formal model in industry, rather a simple way to illustrate why extremes rarely deliver the best outcome. Modern maintenance sits in the middle, powered by real-time insights and prescriptive intelligence.
Reactive maintenance is too cold.
Over-servicing is too hot.
Prescriptive monitoring of asset health is ‘just right’ and helps teams stay ahead without wasting time or budgets.
It’s the natural evolution of maintenance strategies in a world where teams need answers, no ambiguity.
MOVUS can help you put this balance into practice. Our team works with sites to identify where they sit today, determine which assets would benefit most from prescriptive insight, and deploy a reliable solution tailored to their operations.
