PEFF is the metric used for calculating Production Efficiency. It can be found on the Operator Portal, Pitchboards, Dashboards and many Reports.
Calculation for a Pitch
The following formula is used to calculate PEFF for a single pitch:
PEFF = Pitch Actual / Pitch Demand
The result can be multiplied by 100 to be displayed as a percentage.
Calculation for multiple pitches
PEFF is a simple formula that can be aggregated using the following formula:
PEFF = sum(Pitch Actual) / sum(Pitch Demand)
This metric will be prorated in certain areas of the application. Please see the article on Prorated Production Metrics for more information.
- The Pitch Demand can be set many ways. See the Pitch Demand article for more information.
- The back-end calculation uses raw, un-rounded data to calculate PEFF before rounding to the configured precision. The contributing metrics (i.e. actual and demand) have been rounded before being displayed on the screen. If you choose to calculate PEFF manually using rounded metrics, you will get a different PEFF result. (Example: the screen shows a demand of 1 and an actual of 1 but your PEFF is 159% WHAT? It turns out the cycle time for the product is 8400 seconds and the pitch is 76 minutes long which means your demand is actually .63 NOT 1. Therefore the calculation used to get 159% is 1/.63 * 100 = 159%)
- The Production Pitchboard calculates the PEFF for the entire shift as well as the week to date PEFF metrics. There are a couple of things worth note here: The PEFF for the entire shift includes the impending active pitches for the shift. The PEFF metric for the 'Week to Date' does not include future, active pitches associated with that production week.
