OEE

OEE

OEE does take into consideration production counts, but it’s completely its own thing.

OEE is looking at the efficiency of your equipment. That's what the two E stand for.

It's important to remember that OEE disregards any unplanned maintenance time.

So OEE does not consider any out of shift time. It doesn't consider planned maintenance.

OEE is only ever looking at a time where you were intending to make something.

It is then looking at how much of that intended time was lost due to availability reasons and how much was lost due to performance reasons, which means against your target cycle time and then how much was lost due to quality.

That's what OEE is, and it's its own independent metric.

The important thing to remember about OEE as well as it not including unplanned time is, it works off of your intended cycle time.

Your cycle time in manufacturing is part to part, which means any time, like loading the machine, unloading the machine.

Any operation involved in the part to part time is included in OEE.

OEE doesn't look to try and improve the production process itself.

OEE only looks to make sure that you are achieving what you plan to achieve, and that's what differentiates it from productive vs nonproductive time
