## SMART: definitions

Q: SMART: What is the correct definition? How does it relate to OEE?

How should we use SMART when improving the OEE?

## Availability Definitions (1)

1. Excise tax checking time (60 per shipment)
2. Machine cleaning time for the quality of product. (10 min every hr.)
3. External factory Electrical failure time. (uncontrollable)

## OEE – OOE – TEEP explained

Q: What is the difference between the OEE, OOE and TEEP measurements?

## Machines are not always planned to run

Q: We run a 3 shift operation of 120 hrs a week.
Some of our machines are not 100% loaded due to the product mix we have.

How should we calculate the OEE?

## 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?

## 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.

## The relationship between efficiency, effectiveness and productivity

Q: What is the relationship between efficiency, effectiveness and productivity and what is the path that can be followed to bring about ‘improvement’?

## OEE and Six Sigma

Q: I was wondering if there are companies that have used the OEE information for Six Sigma projects and what were the results?
