Overall equipment effectiveness $($OEE$)$ is a key performance indicator that measures how well production resources are used by identifying the percentage of productive manufacturing time. An OEE of $100\%$ means that all products produced are acc$$ptable $(100\%$ quality$),$ and manufactured without interruptions in production availability$).$ Management uses OEE to identify process and performance improvement potential.
