## x 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?

## x Definition 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?

## x Multiple parts with various cycle times

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

## x 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!

## x 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.

## x How to determine Cycle Time?

Q: At my company we are currently doing a book study using your book ‘OEE for the Production Team‘. As we work through the book we came across a question; When calculating OEE do you (the calculation) account for the loading and unloading of material in the machine? We have been calculating the OEE using TAKT time (19 seconds) but the machine cycle time is only (13 seconds). Is this important? Because if there is improvement it will be realized in both versions, correct? In Chapter 9 the exercises do not include load/unload time. Your feedback would be appreciated since material loading is a fundamental function in our facility.
Thank you, Pat Holden

## x Changing the maximum speed

Q: After what time could we change the maximum speed, that results in 100% performance?

## x Performance goes over 100%…

Q:  I’ve been having some difficulties in understanding the definition to calculate OEE. From my experience, it should never be over 100%. However, by definition, performance can surpass 100%.

This will happen whenever the working center is turning faster than standard rate. In this case, should I take the actual cycle time instead of the standard one to limit the performance component at 100%? I need some help, please!
