Preventive Maintenance Vs. Predictive Maintenance: What’s The Difference?

by ronniekongs

Preventive maintenance and predictive maintenance are two sides of the same coin— but they’re not exactly the same thing.

Both are effective strategies for asset maintenance, but you need to understand the differences between the two and how they work together. Here’s a closer look at preventive maintenance vs. predictive maintenance and what you need to know.

What Is Preventive Maintenance?

In a preventive maintenance strategy, facilities managers perform systematic inspections of assets and execute routine maintenance to prevent unexpected equipment downtime or failure. Unlike reactive (or corrective) maintenance where service occurs after the asset has malfunctioned, preventive maintenance requires performing maintenance before anything malfunctions.

Different types of preventive maintenance involve the use of different triggers to determine when to service the equipment. Here are a few examples of preventive maintenance:

  • Time-based maintenance involves completing routine maintenance at scheduled intervals, such as weekly, monthly or annually
  • Condition-based maintenance refers to performing maintenance based on the discovery of physical evidence of potential asset failure
  • Usage-based preventive maintenance involves performing maintenance after a certain threshold has passed, such as hours in use or miles driven

Preventive maintenance is appropriate for assets that are mission-critical for day-to-day operations and are more likely to fail as they age. The extent of the maintenance required on any asset depends on utilization and environmental conditions. However, the American National Standards Institute (ANSI) has general recommendations for what types of inspections and maintenance are needed and how often they should be performed.

How Do You Implement Preventive Maintenance?

Preventive maintenance is different from simply keeping an eye on equipment and following the manufacturer’s recommended repair schedule.

To properly implement preventive maintenance, the facilities team must maintain detailed asset profiles that include information such as asset age, dates of inspection, service records and expected lifespan for every piece of equipment in the company. To ensure the accuracy of these asset profiles, facilities professionals need to use asset management software.

Asset management software gives FMs on-demand access to all these important details in one place. They can see this information at a glance and use it along with facility maintenance software to manage service requests. They can even set up workflows to create automatic service requests when an asset reaches a certain age or utilization threshold.

Facility maintenance software enables facility managers to quickly assign a technician to each ticket and track the status of those tickets throughout the lifecycle. Because the solution stores all of the relevant information, including maintenance manuals, technicians know exactly what to do as soon as they are assigned a ticket.
