1. AN INTRODUCTION TO

3. Reactive Pros
• Low Cost
• Less Staff
Reactive Cons
• Increased cost (e.g., unplanned downtime
• Increased labor cost (e.g., overtime)
• Increased repair or replacement costs
• Possible secondary equipment or process
damage (due to equipment failure)
• Inefficient use of staff resources

4. Preventive Pros
• Cost effective even in many capital-intensive
processes
• Flexibility allows for adjustment of
maintenance frequency
• Increased component life-cycle
• Energy savings
• Reduced process or equipment failure
• Estimated 12% to 18% greater cost savings
than reactive maintenance
Preventive Cons
• Catastrophic failures still likely to occur
• Labor intensive
• Includes performance of unneeded
maintenance
• Potential for incidental damage to components
in conducting unneeded maintenance

6. Preventive
Reactive
PREDICTIVE IS A BALANCE BETWEEN THE TWO
In other words....an Optimized Maintenance Strategy
