Q: According to the fundamentals of ‘method-time measurement’, the standard time of an operation includes some fatigue allowance when the machine is loaded / unloaded manually by an operator.
Should I consider this standard time as theoretical maximum speed? Or should I eliminate the fatigue allowance from the standard time to find the theoretical maximum speed?
Arno Koch • By definition, OEE identifies and visualizes ALL potential EQUIPMENT losses; so also the time the equipment has to wait for the loading/unloading. This might be a subject for an improvement activity.
OEE measures against THEORETICAL maximum speed, not ‘CURRENTLY assumed to be the best possible’.
Hint: When your OEE drops down due to difficult loading and unloading, causing operators to become fatigue; then improve the loading and unloading instead of hiding this by taking it out of the OEE!

Your OEE can perform far more better!
Most OEE implementations do NOT lead to fundamental improvement! And yet, most machines can produce twice the current capacity at lower cost! How? that is the subject in our courses! click here to learn more!
