thinking in systems: a primer review

Nonrenewable resources are stock-limited. A stock governed by linked reinforcing and balancing loops will grow exponentially if the reinforcing loop dominates the balancing one. That mechanism operates through a feedback loop. (About 1/7th of the total size of an iceberg is above the water.) Democracy works better without the brainwashing power of centralized mass communications. Why would you hand over your hard earned money for something you could get for free? It's… your friend Joel's digital garden. (See Social Engineering, Trust Me, and Emotional Awareness for more about Ekman’s work). Reinforcing feedback loops are self-enhancing, leading to exponential growth or to runaway collapses over time. The more that we understand about systems the more we can understand about the organizations we work in, the communities that we live in, and the world as a whole. However, more than allowing the rider to focus on the rope, a delay – the delay between recognizing the motion of the bull and correcting the horse’s motion – has been removed. If they are extracted faster than they regenerate, they may eventually be driven below a critical threshold and become, for all practical purposes, nonrenewable. 89 Issue 6, p202 A system’s function or purpose is not necessarily spoken, written, or expressed explicitly, except through the operation of the system. Systems are the same way. The book is odd in that it was published posthumously. Some systems have espoused purposes which don’t match their actual purposes. It warns against false causalities, simplistic explanations, and impulsive action just as it exhorts empathy and humility in our intellectual endeavours. This means that the economy will move in cycles regardless of what political leaders do. The Thinking in Systems book introduces a reader to a different way of thinking about everyday problems that are found in nature, business, society and life. “Meadows’ Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. They are the storehouse of the system. It is fascinating to explore what remarkable behaviours can emerge even with very simple arrangements of water, taps, and bathtubs! Reinforcing loops are found wherever a system element has the ability to reproduce itself or to grow as a constant fraction of itself. It will level off if the two loops are of equal strength. A system is a set of interlinked elements organized to achieve a goal. But since the stock is not renewed, the faster the extraction rate, the shorter the lifetime of the resource. Reducing buffers increases efficiency (optimization) by reducing resilience. In my mind, systems thinking can really change the way we think about international development, in general but especially in fragile states. There are no ‘true” paradigms. This is part of why wicked problems (See Dialogue Mapping and The Heretic’s Guide to Best Practices) are wicked. 1 Review. 5.0 out of 5 stars Book for work. Cohen, Aaron M. // World Future Review (World Future Society);Jun/Jul2009, Vol. Bounded rationality means that people make quite reasonable decisions based on the information they have. We’ve become adept at identifying the component parts of a system. The right boundary for thinking about a problem rarely coincides with the boundary of an academic discipline, or with a political boundary. Vendor managed inventory reduced the amount of inventory at distribution but this leads to more outages. Read Next : More articles about organizing teams. Story 3 out of 5 stars. The relationship between cause and effect can only be drawn with curves or wiggles, not with a straight line. The book is odd in that it was published posthumously. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. Even non-physical information takes time to feedback into the system. Information Flows—The structure of who does and does not have access to information can reduce malfunctions of human and non-human systems. One of the most frustrating aspects of systems is that the purposes of subunits may add up to an overall behavior that no one wants. If subsystems can largely take care of themselves, regulate themselves, maintain themselves, and yet serve the needs of the larger system, while the larger system coordinates and enhances the functioning of the subsystems, a stable, resilient, and efficient structure results. In fact, Paul Ekman, who developed a mechanism for determining a person’s emotional state through micro expressions says that you can accurately observe the emotion but you cannot know why they felt the feeling. Years ago while speaking about databases terms we talked about atomic transactions. In hierarchical systems relationships within each subsystem are denser and stronger than relationships between subsystems. A powerful introduction to systems … A primer to systems thinking indeed! I was given this free review copy audiobook at my request and have voluntarily left this review. The reduced delay minimizes the oscillations and optimizes the system to improve performance. Paradigms are shared opinions, not facts. Thinking in Systems: A Primer by Donella Meadows is an absolutely wonderful introduction to the world of systems and systems thinking. If you're looking for an introductory book to systems thinking, I strongly recommend this one. Yet in its description of complexity, its admission of "it's effing difficult", its many … The classic example of this is the temperature of a shower as I mentioned in my review of The Fifth Discipline. You can’t extract just part of the complex system update, you have to take it all – or none of it. They are found whenever a stock has the capacity to reinforce or reproduce itself. Thinking in Systems: A Primer - Confident Change Management. One of the challenges that happens when trying to infer the behavior of a system is that you believe that What You See is all there is (WYSIATI). Information holds systems together and plays a great role in determining how they operate. The thrust that the engines are producing is being converted into lift by the wings, but in a non-obvious way. What is most frequently cut when optimizing is anything that’s not directly related to output but sometimes the secondary loops and support structure is necessary to support the system once things start to go wrong. 6. Complex behaviors of systems often arise as the relative strengths of feedback loops shift, causing first one loop and then another to dominate behavior. An optimization towards returns had removed the resiliency from the system. Resilient systems can be very dynamic. Systems can be self-organizing, and often are self-repairing over at least some range of disruptions. At any given time, the input that is most important to a system is the one that is most limiting. Changing the length of a delay may (or may not, depending on the type of delay and the relative lengths of other delays) make a large change in the behavior of a system. One exception is on a discontinuity where a small numeric change causes the system to operate differently. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought … Why are people willing to pay $2 for a bottle of water at the airport? It is a basic book which covers only the most basic principles of systems thinking and modelling. ... An excellent review of systems thinking by Meadows, the material is easy to interpret and there are plenty of relevant examples offered Helpful. Harmonization of goals in a system is not always possible. Locate Responsibility in the System That’s a guideline both for analysis and design. Magical leverage points are not easily accessible, even if we know where they are and which direction to push on them. Self-organization is basically a matter of an evolutionary raw material—a highly variable stock of information from which to select possible patterns—and a means for experimentation, for selecting and testing new patterns. In physical, exponentially growing systems, there must be at least one reinforcing loop driving the growth and at least one balancing loop constraining the growth, because no physical system can grow forever in a finite environment. A system is more than the sum of its parts. When you work you don’t instantly get a paycheck. Rules to govern a system can lead to rule beating—perverse behavior that gives the appearance of obeying the rules or achieving the goals, but that actually distorts the system. Stocks are the elements of the system that you can see, feel, count, or measure at any given time. Systems happen all at once. Flows are the inputs and outputs to that stock. Stocks change over time through the actions of a flow. We saw this in Diffusion of Innovations and The Fifth Discipline as the law of unintended consequences. The stock is the size of the Dead Sea itself –the water contained in it. Written by the late Donnella H Meadows. The system, to a large extent, causes its own behavior! The power of big industry calls for the power of big government to hold it in check; a global economy makes global regulations necessary. In this way, even observing a river doesn’t make transparent all of the factors influencing it. They have an all or nothing component of them. For any physical entity in a finite environment, perpetual growth is impossible. Conditions that encourage self-organization often can be scary for individuals and threatening to power structures. Buffers—The sizes of stabilizing stocks relative to their flows. Therefore, many systems are not meeting our goals because of malfunctioning hierarchies. It lays out the conceptual landscape of the entire discipline in language that is accessible to everyone, including non-technical people. In the case of an airplane the fact that it’s used for transportation is non-obvious at first glance – when you look at the collection of components. The author uses easy to understand language and examples throughout the book. More than teaching the technicalities, the author places a far greater importance on exposing the rich, complicated, and unexpected nature of real world systems through day-to-day examples. You have to take the whole of the system you can’t take the pieces. Changes in stocks set the pace of the dynamics of systems. Thinking In Systems: A Primer by Donella Meadows: This is the one I’ve recommended, referenced and gifted the most. Read honest and unbiased product reviews from our users. You can make one big bet on a particular market, industry, or even company. White River Junction, VT: Chelsea Green Publishing. I had the pleasure recently of meeting a rodeo champion. Find helpful customer reviews and review ratings for Thinking in Systems: A Primer at Amazon.com. The best (if not only) way to deduce the purpose of a system is to see it in operation. Of course we all know that airplanes are designed for transportation – but that’s because we’ve seen them in action. Traditional controls on fishing were sufficient until sonar spotting and drift nets and other technologies made it possible for a few actors to catch the last fish. edit ️. The purpose is also the most difficult to observe. System structure is the source of system behavior. A person can be broken down into organs, cells, molecules, atoms, protons, quarks, etc. It’s an easy read and the chapter structure aids the acquisition of knowledge in chunks that, at the same time, work for the noob and provide the opportunity of quick recall for the expert. The book draft was written in 1993 but was never published. Reinforcing Feedback Loops—The strength of the gain of driving loops which cause the system to want to go out of control – either positively or negatively. For instance, you can see a duck on the surface of the water but you can’t see how much – or little – the duck is paddling underneath the water. A system’s structure defines its behavioral pattern. But we do it all the time. There is a crying need for more intelligent commentary and review. Consider your paycheck. The higher and faster you grow, the farther and faster you fall, when you’re building up a capital stock dependent on a nonrenewable resource. There numerous theories about what the rocks were used for. In most cases elements are tangible. 1 Issue 3, p100 . Stocks allow inflows and outflows to be decoupled and to be independent and temporarily out of balance with each other. It looks great to the people getting a loan on the house but it led to the balancing loops in the system being insufficient to catch the fall. Performance 3 out of 5 stars. However, when problems arise those critical components which were cut can’t kick in to keep the system from collapsing. An outside event may unleash that behavior, but the same outside event applied to a different system is likely to produce a different result. Every animal, plant, organization and society is a complex system. … Thinking in Systems: A Primer. Thinking in Systems: A Primer. As humans we’re more aware of stocks than we are flows. The book draft was written in 1993 but was never published. It’s possible to believe at first glance that learning from The Fifth Discipline might be enough, but systems thinking was only one of the disciplines – it didn’t get the depth that it deserves as a way of thinking that can change your effectiveness. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. If these differential information links within and between each level of the hierarchy are designed right, feedback delays are minimized. A feedback loop is formed when changes in a stock affect the flows into or out of that same stock. Many of the interconnections in systems operate through the flow of information. Transcending Paradigms – By transcending paradigms you can see individual systems for their limitations and put different systems together to get richer results. If we have a stock of money than our outward flows must be acceptable. Taking apart a system should be easy. This system trap is found whenever the winners of a competition receive, as part of the reward, the means to compete even more effectively in the future. Systems fool us by presenting themselves—or we fool ourselves by seeing the world—as a series of events. The greatest complexities arise exactly at boundaries. Any competent financial analyst will tell you to spread out your investments into a variety of industries and types of investment. Stock with Two Competing Balancing Loops—a Thermostat, Stock with One Reinforcing Loop and One Balancing Loop—Population and Industrial Economy, A Renewable Stock Constrained by a Nonrenewable Stock—an Oil Economy, Renewable Stock Constrained by a Renewable Stock—a Fishing Economy. But beware, unlike many others, this book offers no easy solutions. A stock takes time to change, because flows take time to flow – Results are lagging indicators of processes. 4 people found this helpful Overall 1 out of 5 stars. John Mackey is the … Complex systems can evolve from simple systems only if there are stable intermediate forms. Next come some particularly perverse but unfortunately common system behaviours the author called “System Traps”. Delays are pervasive in systems, and they are strong determinants of behavior. These are followed by a list of leverage points which can be acted upon to alter system behaviour effectively, but we have to understand them right. It’s often harder to see the interconnections between the elements in a system. Goals—The purpose or function of the system – and the framing of the goal – are powerful motivators to systems. Resilience is not the same thing as being static or constant over time. Basically this is rebuilding the system which can be very effective but rebuilding a system is also difficult to accomplish so thus it’s not very high up on the list of leverage points. However, in order to approach an understanding of the system – in order to create a mental model of the system (See Sources of Power and The Fifth Discipline) – You’ll have to try to decompose the system into understandable components. Everything is still connected to everything. A system is an interconnected set of elements that is coherently organized in a way that achieves something. However, this is what we often do in optimization. Thinking in Systems: A Primer. … confuse effort with result, one of the most common mistakes in designing systems around the wrong goal. They study people’s behavior around money. We eliminate the parts of the system that we don’t think are necessary because it’s just taking energy to keep operational and isn’t returning value. The book is odd in that it was published posthumously. close. A lot of the theory about teams and organizations has emerged from the principles of systems thinking, and this book explains those principles very effectively. Numbers—Constants and parameters such as subsidies, taxes, standards. If the goals—the indicators of satisfaction of the rules—are defined inaccurately or incompletely, the system may obediently work to produce a result that is not really intended or wanted. Capacity of a system to make its own structure more complex is called self-organization. Thinking in Systems —— A Primer —— ... as “Places to Intervene in a System” in Whole Earth Review (Winter 1997) and later as an expanded paper published by the Sustainability Institute. Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Or is it? It will die off if the balancing loop dominates the reinforcing one. Once we see the relationship between structure and behavior, we can begin to understand how systems work, what makes them produce poor results, and how to shift them into better behavior patterns. Where to draw a boundary around a system depends on the purpose of the discussion—the questions we want to ask. Self-organization produces heterogeneity and unpredictability. If you have ever heard the phrase “all technical problems are people problems” – this book will make it clear exactly why that is. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders … Rules—Incentives, punishments, constraints have a great deal of power over systems. In most cases it takes two or three weeks before you get your paycheck for the time you’ve worked. Resilience is a measure of a system’s ability to survive and persist within a variable environment. modelling complex technical systems like meshes of water hoses. The entire stock is available at once, and can be extracted at any rate (limited mainly by extraction capital). It’s possible that there’s one espoused purpose – and an entirely different actual purpose. One of the reasons why people who make a lot of money spend a lot of money is because of our focus on the stocks. “Meadows’ Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. A delay in a balancing feedback loop makes a system likely to oscillate. Meadows provides the conceptual methods and tools of thinking in systems. Book Review: "Thinking in Systems: A Primer" by Donella H. Meadows don mikulecky Community (This content is not subject to review by Daily Kos staff prior to publication.) It seems our ability to see – and accept – delays is an important part of our success in this world. It can be found only by letting go of more narrow goals and considering the long-term welfare of the entire system. Boundaries are of our own making, and that they can and should be reconsidered for each new discussion, problem, or purpose. The cows graze off of common land. One of the things that he explained was that the horses were trained to follow the bulls. These high-risk loans come with higher interest rates designed to be profitable for the car dealer. In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.”.
