This textbook examines three principal methods of applied systems thinking: systems failures, hard and soft systems methods. Other systems methodologies are described briefly. The book is written in an open learning style with activities, exercises and case studies with an emphasis on practice and technique. It is supported by numerous illustrations, in keeping with the diagramming techniques of systems work.
