Traditional process measurements have focused on utilization, or quality, or speed.
Whether the process being measured is an entire plant or an individual machine the same rule applies: You Get What You Measure.
If you measure and reward speed you will get speed at the expense of quality. When a job is particularly important and operators are instructed to closely watch the quality then speed will go down. If utilization is key than we may decrease preventative maintenance and incur the inevitable breakdowns. We need a balanced measurement.
The OEE measurement is so easy to use because most of
the required numbers are usually already available.
Definitions
OEE needs four simple measurements -
- TOTAL STAFFED TIME - the total time the process has labor scheduled to work in it.
- AVAILABILITY - the time the process has crews scheduled to do work minus set up time, breakdown time and time for meetings and breaks.
- PERFORMANCE - the speed of the process rated against its theoretical top speed. We use the theoretical top speed to allow benchmarking against similar processes world wide.
- QUALITY - the ratio of good product received by the process verses good product delivered to the next process or customer.
