OA (Availability) Metric

Operational Availability in systems is a measurement of how long a 'system' has been available to use when compared with how long it should have been available.

You will find the OA metric on the Operator Portal, Production Dashboards, and in many Reports.

Calculation

Operational Availability (OA) = (Planned Production Minutes - Production Downtime Minutes) / Planned Production Minutes * 100

**If you aren't using the production module and still want to calculate OA; the calculation will use available time instead of production minutes.

Calculation for multiple pitches:

Operational Availability (OA) = (sum(Planned Production Minutes) - sum(Production Downtime Minutes)) / sum(Planned Production Minutes) * 100

Notes:

• In the case of calculating OA, only impacting downtime minutes are taken into consideration. Any planned downtime is not part of this calculation.
• We do not display "Production Downtime Minutes" on the Operator Portal or the Production Pitch Boards. Production Downtime minutes is displayed on the Weekly Production Summary report.

Prorating

This metric will be prorated in certain areas of the application. Please see the article on Prorated Production Metrics for more information.
