The knowledge audit is one of the most frequently used foundational activities in knowledge management today. It creates an inventory of key knowledge assets, which when represented using knowledge maps, is a powerful aid to identifying knowledge gaps, knowledge risks, and knowledge sharing opportunities. This book lays out for the first time in a clear and practical manner the different forms and purposes of knowledge audits, and explains how different kinds of knowledge maps can support their exploitation. While this core activity has very little documented guidance, is inconsistently applied and is currently imperfectly understood, this book will support the development of a knowledge management strategy, create momentum for change, and instil a culture of knowledge asset stewardship at every operational level.
