## How to calculate OEE with mixed output?

Q: Our machine can run mixed output, so several different products, each shift. Till now we just recorded the time the machine was running and the output we had. Our software now requires that we register activities and quantities to account for every minute in a shift. But we are not tracking the number of minutes it ran each product.

## Name Plate Capacity (NPC) versus the ‘Standard’

Q: What is the use of the Name Plate Capacity? When defining OEE, you tell us we have to define the maximum speed per product per machine (the ‘Standard’).

## (How) Can Performance be more than 100%?

Q: When can a performance rate over 100% occur?

## Visualizing all speed losses, including minor stops

Q: We tried to measure speed losses and minor stops electronically, yet although tons of data where gathered, it was difficult to see what we needed to do. How can I visualize all speed losses, including minor stops, in a way that we can reduce them?

## Defining maximum speed

Q: I am arguing with our management about the definition of the maximum speed. They are afraid our OEE will become too low..? How do I proceed?

## Multiple parts with various cycle times

Q: How to determine the “Ideal Cycle Time” in cases of multiple parts with various cycle times?

## Ideal Cycle Time

Q: Why is the ‘Ideal Cycle Time’ (=’Standard’ or Theoretical maximum speed) so important? Why can’t we just use our current running speed, we go very fast!

## OEE & Multiple Cycle Times

Q: We have lathes and machining centers that we use where we have multiple set ups and many different parts  with multiple cycle times run on those machines. We will be applying OEE to these machines and I am curious what others have done when the cycle time for the parts always changes. When a process has a constant cycle time, Performance measures also remain constant. Averaging cycle times will not provide accurate information.
