## How high should the OEE be?

Q: I have been reading in different sources about the OEE measurement and I have not been able to find any concrete agreement about what the value for OEE should be. Could you please give me any references?

I have read that there is no common agreement but that it is generally suggested that bellow 65% should be considered unacceptable, since it represents a very low competitiveness and a great number of economic losses. A value between 65 and 75% is considered as regular, only acceptable if it is being improved. A value between 75 and 85 % means an acceptable level with slight economic losses and which can be easily improved to World Class levels. A value between 85 and 95 percent is considered as good and equals World Class values; it represents a high level of competitiveness. And finally, a value above 95% is considered as excellence; an excellent competitiveness and World Class values.

## How to treat machines when there is no demand?

Q: Some of our machines are not being used every day on the demand of the product. So, I don’t evaluate those machines when they remain idle. But, as per my boss, those idle machines should also be evaluated (i.e. OEE =0) and should be presented in monthly graphical reports. Is it correct to calculate OEE of those machines while they are not running?

## Calculate a monthly OEE

Q: My boss wants me to calculate and present a graphical OEE representation on a monthly basis. I present this as I do with the daily data. I calculate the monthly OEE  by taking the average of the daily OEE’s.

Is it alright to present a monthly OEE of the machines by calculating the average of the daily OEE’s in a month?

## Evaluating performance of machines

Q: I have been asked by my boss to evaluate the performance of the Machines in our factory and I found the implementation of OEE is the best way. Now I have some questions about how to define OEE, I have been following this website which helps me a lot.
