AN INTRODUCTION TO

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

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

Preventive

Reactive

PREDICTIVE IS A BALANCE BETWEEN THE TWO

In other words....an Optimized Maintenance Strategy
