Overall Equipment Effectiveness, or OEE, has several benefits over simple one-dimensional metrics like machine efficiency. If you are not meeting demand and have a low OEE (equipment is underperforming) then you know you have an equipment effectiveness problem. If equipment is operating at a high OEE but not meeting customer demand, you know you have a capacity problem. Also, OEE lets you understand if you have spare capacity to keep up with changes in demand.
Once you have cleared the important hurdle of configuring and collecting OEE data, what do you do with it to start improving OEE? The entire purpose of OEE is to highlight losses, so all losses must be analyzed, prioritized, and minimized. This can be a bit overwhelming at first, so where do you begin?
