Supply chains for electronic products are primarily driven by consumer electronics. Every year new mobile phones, computers and gaming consoles are introduced, driving the continued applicability of Moore's law. The semiconductor manufacturing industry is highly dynamic and releases new, better and cheaper products day by day. But what happens to long-field life products like airplanes or ships, which need the same components for decades? How do electronic and also non-electronic systems that need to be manufactured and supported of decades manage to continue operation using parts that were available for a few years at most? This book attempts to answer these questions. <p>This is the only book on the market that covers obsolescence forecasting methodologies, including forecasting tactics for hardware and software that enable cost-effective proactive product life-cycle management. This book describes how to implement a comprehensive obsolescence management system within diverse companies. <i>Strategies to the Prediction, Mitigation and Management of Product Obsolescence</i> is a must-have work for all professionals in product/project management, sustainment engineering and purchasing.</p>

<p><b>A complete set of tools for managing obsolescence in long-field life systems</b></p> <p>As new electronic component technologies are developed, the older component technologies and the components themselves often become obsolete. This obsolescence of components can pose a serious risk for systems that rely on such components, especially if the systems have long-life requirements. The first complete, self-contained book to address this growing global industrial problem, <i>Strategies to the Prediction, Mitigation, and Management of Product Obsolescence</i> provides engineers and managers with the tools they need to implement a comprehensive obsolescence management system in diverse industries, from defense and aviation to communications and industrial controls.</p> <p>The book begins with the fundamental issues associated with the occurrence of obsolescence, then goes on to present a complete process for predicting and managing obsolescence using principles of project management. Both reactive and proactive strategies for managing obsolescence are discussed, as well as how to strategically plan the life-cycle management of systems. Coverage includes:</p> <ul> <li> <p>Obsolescence forecasting methodologies, including those based on sales curve forecasting and procurement life analysis</p> </li> <li> <p>Case studies illustrating obsolescence forecasting for different component types</p> </li> <li> <p>Forecasting tactics for both hardware and software obsolescence</p> </li> <li> <p>All aspects of components' life-cycles, from design and introduction to obsolescence</p> </li> <li> <p>How to deal with discontinued or changed parts, including methods and controls commonly used by semiconductor manufacturers</p> </li> <li> <p>Obsolescence management standards, guidelines, and standards-setting organizations</p> </li> </ul> <p>A must-have work for all professionals in product/project management, sustainment engineering, and purchasing, this book is an invaluable resource for anyone wishing to learn how to mitigate the adverse effects of obsolescence on systems and products.</p>
