Crew Efficiency- Actual Hrs Completed / Estimated Time
Work Process Productivity
Maintenance Cost/ Net Asset Value
Over Time Hrs as % of Total Labor Hrs <5%
Process Availability %- Actual Production/ Total Planned Production
Downtime Losses Trend
Annual Maintenance Cost/ Total Operation Cost Trend

Relief of planned Backlog 60%
Ratio Planned/unplanned labor hours 9:1
% of Emergency WOs <10%
% of Planned Work >80%
% of Up Time >90%
% of Predictive Planned Maintenance Work
Annual Training Per Mechanic
Hrs: >100/yr
Pounds:
Percent of Maintenance Labor Budget Relative to Total
Maintenance Budget
10%

5. •Availability= Available Time/ Total Working Time
Available time=total working time – downtime
•Reliability=Total Working Time-Total Downtime/Total Working
Time-planned
•Mean Time Between Failures (MTBF)=Total Working Time/ Total No Of
Failures.
•Mean Time To Repair (MTTR)= Total Repair Time/ Total No Of Failures.
•Mean Time Between Repairs= MTBF-MTTR
•OEE= Availability x Quality x Efficiency
Quality=Total-Rejected/ Total
