Understanding, Measuring, and Improving Overall Equipment Effectiveness: How to Use OEE to Drive Significant Process Improvement explains why the Overall Equipment Effectiveness (OEE) measure was created and how it should be used. Based on 20 years of hands on experience applying OEE at over 150 sites, this step-by-step practical guide provides templates, assessments, a comprehensive loss-analysis framework to identify all possible variables that could affect OEE, and supporting spreadsheets to measure and improve OEE. It outlines the different operational situations in which OEE can foster improvements, and the implications, before providing an easy-to-understand template for creating appropriate definitions for all the losses and a loss model. The author explains how to calculate OEE using examples to improve performance, and then shows, in detail, how to use an OEE Loss Analysis Spreadsheet to understand all losses, set an ideal vision, and then classify losses so improvement can be approached in the most sustaining way.
