This book is written by a developer and architect with 9 years' experience building Information Worker solutions, including custom workflow engines and third-party workflow products. The author challenges readers to view the Office System and workflow in a new light, walking readers through the process of building a solid, useable workflow solution. Unlike quick references that scratch the surface of new technology, this book benefits the serious Information Worker developer - a growing group in IT - who is interested in learning the inner workings of workflow and Office 12.
