Chapter 15 Your Journey as an Action Researcher while Using Systems Thinking

It's clear to me that pursuing action research is the best way to advance systems thinking and practice. This book is a significant step forward in that regard bringing together as it does systems theory, methodological practice and case studies.Professor Mike C Jackson OBE, Emeritus Professor, University of HullResearch with impact is challenging to do, this book shows a way to do this. It gives a detailed methodology and techniques, show how to abduct to theory and illustrates its narrative with beautiful diagrams from real cases.Professor Janet Godsell, Professor, Loughborough UniversityThis book is highly recommended for its holistic and structured approach to understanding and improving organisational processes as dynamic, interrelated systems that drive sustainable performance. Although systems thinking underpins change it is difficult to practice; this book achieves this with gravitas.Professor Umit Bititci, Emeritus Professor, Herriot Watt UniversityAction research is about accessing meaning through rigorous attention to how issues are constructed, how actions are planned, implemented, and evaluated, and how learning captured informs practical and theoretical knowledge; it can benefit from the scholarly application of a well-defined methodology as presented in this book.Professor Paul Coughlan, Professor, Trinity College Dublin
