When it comes to maintenance, your organization is either taking a proactive approach or a reactive one.
It’s been proven that proactive strategies, like preventive and predictive maintenance, can improve a facility’s bottom line in many ways: lowering maintenance costs, improving asset reliability and giving a 360-degree view of performance, just to name a few.
However, a majority (66%) of organizations still rely on reactive practices to keep their operations going.
Here, we’ll discuss each strategy to show the long-term benefits of proactive maintenance approaches.
A reactive approach means you’re running an asset until it fails and needs repairs, also known as run-to-failure.
Up front, run-to-failure seems like the easiest, most cost-effective strategy to implement. It requires little planning and minimal staff, and there’s no need to train technicians on prevention methods or asset tracking software.
Over time, though, the inconsistency of the run-to-failure method will take a toll on your maintenance budget and overall productivity. This approach makes it hard to anticipate the required labor and parts needed for a repair, resulting in unexpected expenses associated with product loss, overtime labor and spare part storage/purchasing.
Preventive maintenance involves planned, regularly performed tasks to check, clean and maintain assets to reduce failure and downtime.
With this maintenance method, you want 80% of your maintenance initiatives to be planned and only 20% to be unexpected. Doing so will make your assets more reliable, which can positively impact productivity and profitability.
However, getting to an 80/20 ratio does take a significant amount of effort to schedule, prepare and delegate tasks. Preventive maintenance also doesn’t consider an asset’s wear, which can cause facilities to conduct excessive maintenance when a piece of equipment might need replacing.
Instead of following a schedule of planned maintenance tasks, predictive maintenance is a strategy where tasks are conducted based on trends within asset data.
This method requires expert observation and specialized tools, such as vibration analysis and thermal imaging, to collect data on the equipment’s efficiency and wear, making the upfront costs of implementation expensive.
However, this data-driven approach to predictive maintenance gives facility managers and technicians full visibility of an asset’s performance. The strategy also uses algorithms to predict when an asset may fail, ensuring downtime only occurs before an unavoidable failure. This can reduce product loss and increase efficiency, directly improving a company’s profitability.
Which Proactive Strategy Should I Choose?
There’s no right or wrong approach to proactive maintenance. Choosing between a preventive or predictive strategy is up to the needs of your facility and your resources for purchasing and maintaining the required technology.
The major difference between the two methods is the amount of downtime involved.
Preventive maintenance relies on planned tasks that are scheduled based on time passed or sensory triggers. Typically, these tasks involve shutting down and disassembling equipment, like for an oil change or applying lubrication.
Predictive maintenance, though, uses algorithms to identify trends in asset data and predict when failure will occur, allowing maintenance teams to prepare spare parts, productivity alternatives and labor required ahead of time. This method typically collects real-time data through sensors and specialized tools, meaning predictive maintenance usually occurs while equipment is operating.
Although the execution tactics are extremely different, both methods can be used together for a well-rounded maintenance strategy that expands your asset’s life-cycle to its fullest potential.
Preventive and predictive maintenance have similar objectives: to make regular maintenance more routine and allow facilities to improve their bottom line.
Whether you mix both methods for a fully developed maintenance routine, or use one as your budget allows, implementing a proactive maintenance strategy can lead to continuous improvement, increased asset uptime and reduced spending on unexpected repairs.
