Preventive vs Predictive Maintenance

Though Preventive maintenance (PM) and Predictive Maintenance (PdM) are different forms of maintenance, they both help to improve the lifespan of assets. They prevent the occurrence of breakdowns thus, saving costs. Each type of maintenance generates incident reports ranging from work orders to servicing and initiate requests to schedule maintenance ahead of when assets need to be taken care of. These make both a form of scheduled maintenance task.

Preventive maintenance and predictive maintenance are different methods of safety. The key difference is that preventive maintenance is scheduled regularly while predictive maintenance is planned if necessary- based on the condition of an asset.

Preventive maintenance reduces the cost of labour and material costs. The application of a predictive maintenance program demands a lot of training, resources, and capital from the get-go. Often, these costs are acceptable to organisations that have successfully implemented a preventive maintenance system.

Here, we define the difference between preventive and predictive maintenance and explain when your organisation should be using one over the other.

What is Preventive Maintenance?

 Preventive maintenance also is known as planned maintenance or planned preventive maintenance and is performed even when assets are functional to prevent possible breakdowns. This form of maintenance is like a regular check-up. While the main target of the system is to cut down on the re-occurrence of breakdowns, it also serves in extending the lifespan of machinery and asset. Thus, increasing productivity through efficiency. 

While preventive maintenance has been the ruling maintenance system used by most professionals, it is not without its risks. Cost being the first; we cannot pull out all our capital budget on maintenance alone. We need to make informed decisions on which asset requires maintenance and when. With proper understanding, you can avoid unnecessary maintenance and reduce costs. 

What is Predictive Maintenance?

Predictive maintenance also popularly known as condition-based maintenance. It requires fixed and preset conditions. Simply put, it works to foretell failure before it happens by monitoring the machine in its normal operations. Variances from the conditions found during routine checks provide the needed data to perform any maintenance required. This avoids equipment breakdown or to organ repairs with scheduled maintenance, thus reducing costs.

Predictive analysis spots an issue and then can plan repair during a period that reduces the impact on production. Thus, reducing the impact of downtime. Costs associated with predictive maintenance when compared to that of preventive maintenance can be higher. In essence, you can save costs by reducing unnecessary maintenance.  

Choose the Right Maintenance Program

Identifying the right maintenance program you can avoid unnecessary breakdowns which results in unplanned care. Doing this will also help to maintain a status log of your assets. Computerized maintenance management systems (CMMS) are a good choice can help businesses or organisations stick to predefined checklists and standards of operation and develop a maintenance plan that will help:

  • Determine a maintenance timetable
  • Determine the maintenance required for an asset through proper monitoring
  • Keep costs on the low while meeting deadlines and budgets of your processes
