Maintenance Indices - Meaningful Measures of Equipment Performance

Every industry has its own indices, metrics, measures, and KPIs they use on maintenance. The main reason why we measure these indices is to determine if our maintenance organization is moving forward in the right direction. However, some indices may not be as simple as we think. This book is not just about knowing the formulas, and equations to use but having a deeper understanding of what we include and exclude in them. Some of these includes:

What formula are we using on Availability, especially when calculating OEE?

If a shipment was returned to the plant because of defects, is the Quality Rate adjusted on the date the product was manufactured?

If the machine is not loaded and sitting Idle, is the No-Load included as a Planned Downtime?

Is maintenance in agreement with this that no load is a Planned Downtime?

Is set-up and changeover a Planned or Unplanned downtime?

Have we separated on what to include and exclude as Planned and Unplanned downtime?

Have we agreed on what we shall consider a breakdown and not a breakdown?

Is everyone clear on the definition of breakdown and what do we include as breakdown or not especially in calculating MTBF, and MTTR where the denominator is the frequency of failures and breakdown.

For manufacturing industries who suffered minor stoppages in their equipment, are these losses clearly separated from the breakdown especially when the downtime is prolonged due to no available technician.

There are many interesting topics I have written that should provide the reader some clarification on t Selecting the Right KPI's for Maintenance
