Optimizing PM Strategy

Balance costs against reliability — too little PM leads to breakdowns, too much wastes resources.

Key Metrics

• PM Completion Rate — % on time
• PM-to-Corrective Ratio — Target 80:20
• MTBF — Higher is better
• PM Cost vs Breakdown Cost
• Schedule Adherence

Optimization Tips

• Start with manufacturer intervals, adjust based on data
• Review quarterly — extend intervals if inspections always pass
• Focus on critical production assets
• Use meter-based triggers when usage varies
• Track which PM tasks actually prevent failures

Reviewing a plan's interval with your own data

Open a time-based or hybrid plan, then its “Analytics” tab: the “Interval review” card covers the last 12 months (or the period since the interval last changed). It counts how often the plan was done on time or late, the failures on the same asset while the PM was on time versus overdue, the defects found during its checks and the downtime recorded, then gives a verdict — schedule adherence, review this plan, stable, or not enough data. It never changes the interval for you: a failure can have nothing to do with what this PM checks, so look at its failure code before editing the plan's frequency.
