Gharajedaghi's book is not only a necessary addition to any systems library, but a MUST for everyone's hip pocket - whether doctor, lawyer, cleric, business person, nurse, educator and human being living now. Gharajedaghi has provided the conceptual framework and operational methodology in an exceptionally readable, and very useable text. This book is not the typical "how to" book, giving steps to follow; but provides the depth theory and background necessary for user UNDERSTANDING now, and frees the user to design and create interventions well into the 21st century. If you are interested in "making sense" out of the chaos and complexity around you; if you are interested in providing the necessary structure, process, and function that equates to a new business architecture in your environment, then you have found the best resource in this book. It is most inclusive, it goes from A to Z, and further you will not find as comparable and complete a resource anywhere, for it readys you for the 21st century. Thus check your hip pocket, and add SYSTEMS THINKING: MANAGING CHAOS AND COMPLEXITY:A PLATFORM FOR DESIGNING BUSINESS ARCHITECTURE, if necessary.
