1998 57 vortec wiring harness diagram: Car Guys vs. Bean Counters Bob Lutz, 2011-06-09 A legend in the car industry reveals the philosophy that's starting to turn General Motors around. In 2001, General Motors hired Bob Lutz out of retirement with a mandate to save the company by making great cars again. He launched a war against penny pinching, office politics, turf wars, and risk avoidance. After declaring bankruptcy during the recession of 2008, GM is back on track thanks to its embrace of Lutz's philosophy. When Lutz got into the auto business in the early sixties, CEOs knew that if you captured the public's imagination with great cars, the money would follow. The car guys held sway, and GM dominated with bold, creative leadership and iconic brands like Cadillac, Buick, Pontiac, Oldsmobile, GMC, and Chevrolet. But then GM's leadership began to put their faith in analysis, determined to eliminate the waste and personality worship of the bygone creative leaders. Management got too smart for its own good. With the bean counters firmly in charge, carmakers (and much of American industry) lost their single-minded focus on product excellence. Decline followed. Lutz's commonsense lessons (with a generous helping of fascinating anecdotes) will inspire readers at any company facing the bean counter analysis-paralysis menace.
1998 57 vortec wiring harness diagram: Job Shop Lean Shahrukh A. Irani, 2020-05-04 In the 1950’s, the design and implementation of the Toyota Production System (TPS) within Toyota had begun. In the 1960’s, Group Technology (GT) and Cellular Manufacturing (CM) were used by Serck Audco Valves, a high-mix low-volume (HMLV) manufacturer in the United Kingdom, to guide enterprise-wide transformation. In 1996, the publication of the book Lean Thinking introduced the entire world to Lean. Job Shop Lean integrates Lean with GT and CM by using the five Principles of Lean to guide its implementation: (1) identify value, (2) map the value stream, (3) create flow, (4) establish pull, and (5) seek perfection. Unfortunately, the tools typically used to implement the Principles of Lean are incapable of solving the three Industrial Engineering problems that HMLV manufacturers face when implementing Lean: (1) finding the product families in a product mix with hundreds of different products, (2) designing a flexible factory layout that fits hundreds of different product routings, and (3) scheduling a multi-product multi-machine production system subject to finite capacity constraints. Based on the Author’s 20+ years of learning, teaching, researching, and implementing Job Shop Lean since 1999, this book Describes the concepts, tools, software, implementation methodology, and barriers to successful implementation of Lean in HMLV production systems Utilizes Production Flow Analysis instead of Value Stream Mapping to eliminate waste in different levels of any HMLV manufacturing enterprise Solves the three Industrial Engineering problems that were mentioned earlier using software like PFAST (Production Flow Analysis and Simplification Toolkit), Sgetti and Schedlyzer Explains how the one-at-a-time implementation of manufacturing cells constitutes a long-term strategy for Continuous Improvement Explains how product families and manufacturing cells are the basis for implementing flexible automation, machine monitoring, virtual cells, Manufacturing Execution Systems, and other elements of Industry 4.0 Teaches a new method, Value Network Mapping, to visualize large multi-product multi-machine production systems whose Value Streams share many processes Includes real success stories of Job Shop Lean implementation in a variety of production systems such as a forge shop, a machine shop, a fabrication facility and a shipping department Encourages any HMLV manufacturer planning to implement Job Shop Lean to leverage the co-curricular and extracurricular programs of an Industrial Engineering department
