What is overall equipment effectiveness (OEE)?
Overall equipment effectiveness, or OEE, is a single metric that shows how well a piece of manufacturing equipment is actually running. It combines three things: how often the machine is available, how fast it performs, and how much of its output is good quality.
The beauty of OEE is that it catches losses people miss. A machine can look busy while quietly losing time to small stops, slow cycles, and scrap. OEE rolls all of that into one honest number.
Chasing a higher OEE is one of the clearest ways to find hidden capacity without buying new machines.
Sthenos builds the tracking behind metrics like this, as in the MES built for a manufacturing firm.

What is a good OEE score?
It varies by industry, but world class operations often aim for the mid eighties. The real value is improving your own number over time.
