The world around us is comprised of systems - organisational systems, business systems, political systems, family systems, inter-personal systems, biological systems, economic systems - the list goes on.This eBook, written by an experienced systems thinker and consultant, helps the reader develop an appreciation of the nature of systems - what they comprise of, how they function, how they sustain and organize themselves and what they influence and are influenced by. With this knowledge people and organisations can obtain a greater understanding of themselves and can develop the ability to identify the structure of problems and make interventions with far greater skill and precision.
