Sharing knowledge in policing remains a significant challenge for police forces around the world. The Bichard Inquiry examined the effectiveness of police forces' information sharing and found it to be severely lacking. This unique book sets out the conceptual framework for knowledgemanagement and explains how a greater understanding of the subject can help policing at an operational level. The book is split into a clear and logical three part structure: Part I covers the foundations of knowledge management and the key security issues in relation to a 'globalised' world of crime and terrorism, Part II looks at the building of structures and the use of applications and Part IIIintegrates the first two parts by providing illustrative examples of working applications of police-specific knowledge management systems. Drawing on examples from around the world, the book takes the reader through the range of different systems and approaches and shows how they can be implemented in practice using illustrative case studies and practical diagrams.This is an ideal purchase for all police professionals and policing academics with an interest in, or role in knowledge management systems.
