Edited by experts, this book brings together the collective experience of trail blazers. A glance through the contents demonstrates the breadth and depth of coverage, not only in topics included but also in expertise provided by the chapter authors. They are the pioneers, who, while initially making it up as they went along, now provide the next generation a guide to success. This is not a how-to book or a collection of technical data, it does not cover products or technology or provide a recapitulation of the common body of knowledge. Capturing years of hard knocks, success stories, and yes, failures, it delineates information needed and includes from-the-trenches advice on how to have a successful career in this field.
