Overall equipment efficiency (OEE) measures the ratio of how much of a product or part is being made defect-free versus how much could be made according to the equipment's design. A machine or process that has an OEE of 100 percent is producing at its maximum designed capacity with zero defects. OEE availability is a time metric that usually measures as a percentage of the operating time. Machine availability is a measure of how much time this machine was available to manufacture a product or part. Improving the machine's availability time by reducing wastes and excess motions from the process can reduce costs by a large amount. The more wastes removed from the process, the less time will be needed to produce the target. Overtime and excess resource issues usually result from an improper utilization of the operating time.
