Preventive Maintenance

Achieve higher reliabilitywith less maintenance

Most PM programs were never developed properly. Between 40% and 60% of the tasks in a typical program add little value. Build your program on the principles of Reliability Centered Maintenance and you prevent the failures that matter, with less maintenance rather than more.

Prevention versus consequences

We don't maintain equipment to prevent failures. We maintain it to prevent the consequences that matter.

Some failures you can accept, because the consequence is small. Others you go out of your way to prevent. Most PM programs don't make that distinction. The result is wasted effort on low-value tasks while the failures that hurt still get through.

Target the right failures

Match every task to a failure mode and its consequence. If a task doesn't prevent a consequence you care about, cut it.

Choose condition over time

Replace fixed-time intrusive overhauls with condition-based tasks where they are more effective, cheaper, and less disruptive to production.

Set frequencies from data

Use your own failure data and experience to set task frequencies, instead of copying OEM defaults and never reviewing them.

Less maintenance, higher reliability

Increase your reliability, by doing less work.

Online training

Most PM programs weren't developed. They accumulated.

Tasks copied from OEM manuals, tasks added after incidents, tasks nobody has reviewed in years. PM100 teaches your team how to build and improve a PM program deliberately, using the principles of Reliability Centered Maintenance.
