Increasing competitive environments and markets have forced manufacturing organisations to continuously seek improvements in their production processes as an alternative to reduce operational costs. In this context, the ability to measure performance is a key factor in the success of any improvement initiative. Two of the most important and used metrics of performance in manufacturing are productivity and quality. This book establishes the relationship between two highly used measures of productivity and quality, Overall Equipment Effectiveness (OEE) and Process Capability (PC). In addition, the book also proposes Overall Resource Effectivenes (ORE) as an improved measure of equipment and process effectiveness. The book provides a useful perspective and guide to understand the interaction of different elements of performance in manufacturing processes. This may help managers to take better decisions about how to run and improve their manufacturing operations more effectively and efficiently. Therefore, this book should be especially useful to academics and practitioners in the field of operations and production management.
