Efficiency is a way to measure compliance to the preset standards. It can be calculated over a given period by work center: Standard hours calculated for a given production divided by the actual hours worked.
Efficiency makes it possible to correct the standard times of the routing (multiplying factor) according to the used resource.

Two efficiency rates are managed depending on the following:

• Work center: The rate is applied to all the routing operations that will take place at the work center.
• Routing operation: The rate only applies to the considered operation.

If both factors are entered, they add up.
The calculated operating time is corrected in the following way: work center efficiency * operation efficiency * time.

The WSTEFFINH - Work center efficiency history parameter (GPA chapter, MIS group) is used to specify whether the efficiency defined at work center level should be used on the routing operation.

• If WSTEFFINH is set to Yes, the efficiency entered in the work center is suggested by default when creating the routing operation with this work center. The calculated runtime = runtime entered * 1 / operation efficiency.
• If WSTEFFINH is set to No, the efficiency entered in the work center is combined with that entered in the routing operation. The calculated runtime = runtime entered * 1 / work center efficiency * 1 / operation efficiency.
