This book explains why the Overall Equipment Effectiveness (OEE) measure was created and how it should be used -- many senior managers and even consultants wrongly use it to compare performance between equipment and sites. It outlines the different operational situations in which it can be used, and the implications, before providing an easy-to-understand template for creating appropriate definitions for all the losses and a loss model. It shows how to calculate OEE using examples to improve performance, such as the application of a loss model and Pareto charts. It provides a detailed step-by-step outline of how to analysis a production line to identify all possible issues that could affect OEE performance. The book 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. In addition, it addresses the issues associated with automating OEE Data Capture and includes an appendix containing an OEE Improvement rating sheet to determine where you are compared to best practice.
