Moving Beyond OEE Limitations Arriving at Total Production Efficiency
May, 2013
For the past five years manufacturing plant managers and supervisors have adopted lean manufacturing principles, eliminated waste, and still seen total production efficiency elude them. Monitoring and Overall Equipment Effectiveness (OEE) solutions in the shop extracted little value because most "OEE monitoring" technology use tools that generate data, but none that help them make sense of it. OEE is an effective metric to give an overall sense of how effectively manufacturing equipment is performing; it is not particularly useful in improving shopfloor productivity.
OEE is a composite metric, combining machine availability, part quality, and schedule adherence. At best, OEE conflates each of these individual aspects of productivity, and at worst, OEE incorrectly inflates a device's productivity by one of the three metrics, overwhelming the others. OEE-based monitoring tools have also emphasized data collection and reporting, aggregating OEE and its constituent metrics from…
