Strategic CX: A Deep Dive into Voice of the Customer Insights for Clarity
OEE - The Final Metric - Pure Precision LLC
1. Effectiveness is defined as; the degree to which something is successful in producing a desired result, so ask yourself, “Are my machines delivering the production I expected?”
If you have ever questioned your equipment’s production output, the next question is, “have you ever measured it”?
Measured World Class
UTILIZATION 83% 90%
PERFORMANCE 83% 95%
ACCEPTANCE 98% 99%
OEE 68% 85%
It is clear to see where attention is needed and from my experience these are the two highest offenders in most shops. Now how do you fix it? You could do a quick
calculation from your machines controller and find the ‘chip time’ but that only gets you a ‘30,000 foot’ view. You’ll need to ‘peel the onion’ to get a granular view of the
‘Sources of Loss’ that are causing poor ‘Utilization’ and ‘Performance’. If you would like to find hidden capacity this is the ticket. If you are looking to get the most out of
that huge investment this is the path you need to take! Give us a call and we will customize a solution exactly for your situation.
World Class is recognized as
such. That said your situation
may vary, BUT don’t let that be
the ceiling! Hence the name
‘Continuous Improvement’

That’s were OEE or ‘Overall Equipment Effectiveness’ comes in. This is a proven metric that is actually three metrics rolled up. They are ‘Utilization’, ‘Performance’ and
‘Acceptance’. Each equally significant on their own, but an extremely harsh metric when conjoined into OEE. Why? Because when you multiple the three together, any one can
degrade the combined OEE metric. It forces the ‘Complete’ effectiveness of your equipment. So what makes up these three metrics?
‘Utilization’ is the actual production time against the total production time. If you machine was ‘making chips’ for 400 minutes of an 8 hours shift (480 minutes), ‘Utilization’
was 83%.
‘Performance’ is the actual parts per hour the machine produced against the MDR or maximum demonstrated rate. MDR is the best rate that that part ever historically ran. If
your actual rate was 10 parts per hour and the MDR was 12, “Performance’ was 83%.
‘Acceptance’ is the time lost on scrap against the total time required to make parts. If the machine scrapped 1 part of a total of 40 made, and the cycle time per part was 10
minute each, ‘Acceptance’ was 98%.
