This is a nice basic text about systems The layout is clear The diagrams are helpful The volume is an introduction Much of it overlaps with what is in The Limits to Growth The 30Year Update but without the specific focus The opening chapters here I felt could have been boiled down I found myself skipping and sliding over paragraphs but if you completely new to systems thinking the slow pace is probably helpfulIn chapter four Meadows argues that one of the reasons why economic modelling is flawed because it concentrates on flows not stocks eg production rather than productive capacity and doesn't consider the dynamic between them There's a nice discussion of bounded rationality as opposed to the complete information assumed to be available to homo economicus due to the time delays inherent in information feedback and the absence of data which means that in real life we get tragedy of the commons type events occurringChapter five on systems traps I thought was particularly good with aninteresting comparison on population policy in post world war two Romania Hungary and Sweden Attempts in Romania to increase the birth rate by banning abortion led to an increase in deaths from back street abortions and an increase of children abandoned at orphanages While in Hungary there was a focus on building instead to counter people delaying having families due to a lack of housing ie addressing a cause rather than a symptom of the problemThere's a nice rehabilitation of President Carter who attempted to deal with the Oil Shock in the USA by introducing a tax on imported oil that would rise in proportion to the amount of oil imported and with illegal immigration by investing in development in Mexico instead This rather sums up the difficulty that you face through thinking in systems Because the results are counter intuitive the feel good message of a President Reagan that addresses symptoms are easily grasped than policies that address causes of problems be it addiction to oil or differing levels of development in North America having an effect like osmosis on populations

Thinking in Systems A PrimerCentury lifeSome of the biggest problems facing the world war hunger poverty and environmental degradation are essentially system failures They cannot be solved by fixing one piece in isolation from the others because even seemingly minor details have enormous power to undermine the best efforts of too narrow thinkingWhile readers will learn the conceptual tools and methods of systems thinking the heart of the book is grander than methodolog. I recommend Thinking in Systems because it has changed the way I understand and relate to my world Published after Donella Meadow's death it introduces Systems Thinking by way of definition illustration and application In Part 1 System Structure and Behaviour Meadows uses two graphical tools to analyse systems stock and flow diagrams to show system structure; and charts mapping stock or flow levels over time to explore system behaviour for specific scenarios The diagrams can be used to display balancing aka negative and reinforcing aka positive feedback loops and the charts to explore how these might play outWhile some of the systems might seem simplistic they build up understanding of a key Systems Thinking insight that systems generate their own behaviour And if you're ever wondered why the heroes and villains style of explanation only works in retrospect this is a damn good explanationChapter two The Zoo is a library of common system structures and their behaviour Those of us from the software world will be reminded of a patterns library Again these patterns illustrate a deeper insight that systems with similar feedback structures produce similar dynamic behaviors even if the outward appearance of these systems is completely dissimilar p 51In Part 2 Systems and Us Meadows applies Systems Thinking to our world Many of the examples are dated but I found myself thinking how applicable these patterns and insights were to topics I was currently encountering for example I can't help thinking she would have loved the way that Kanban reflects a systems learning that the ability of people and organisations to execute tasks degrades rapidly as the number of tasks rises beyond a critical limitOf course one natural and urgent interest in systems behaviour is how to change it If worshipping heroes and lynching villains isn't going to reform systems that may exhibit non linear perverse or self preserving behaviour what is In Part 3 Creating Change in System and in our Philosophy Meadows gives us a dozen leverage points for changing systems starting with the simplest and ending with the most powerful She finishes with a list of systems wisdoms attitudes and values that she and others she respects have adopted to make them effective at understanding and changing the systems we live in Like many of the other reviewers I wish I'd read this book a long time ago It has its limitations I'd love to see recent examples and can't help wondering if there are any open source Systems modelling resources But for me this is a book of timeless value for anyone interested in a better understanding of their world and their options in it
