For example, we want to support constant incremental changes so that we can improve the business outcome of these systems based on short feedback loops.

A second aspect is that not only do we have to build and run the software, but we also want to optimize the overall process. Microservices form loosely coupled, distributed systems. One aspect stems from the technology and architecture in the cloud.

By contrast, the key to successful intervention is identifying the Leverage Points where relatively minor alterations can effect a substantial change to a system's behaviour. A range of common errors or policy traps are discussed, such as 'the tragedy of the commons' and 'rule beating', that prevent effective intervention, or lead to good intentions causing greater damage.

The final section of the book explores how to improve the effectiveness of interventions to improve systems behaviours. In particular, it focuses on the roles of feedback loops and the build up of 'stocks' in the system which can interact in highly complex and unexpected ways. The main part of the book walks through basic systems concepts, types of systems and the range of behaviours they exhibit.

Therefore, it is more important to understand the internal structures of the system, than to focus on specific events that perturb it. The connections and feedback loops within a system dictate the range of behaviours the system is capable of exhibiting. The central concept is that system behaviours are not caused by exogenous events, but rather are intrinsic to the system itself. I have kept the discussion nontechnical because I want to show what a long way you can go toward understanding systems without turning to mathematics or computers. It is intended for people who may be wary of the word “systems” and the field of systems analysis, even though they may have been doing systems thinking all their lives. This book is about that different way of seeing and thinking. Thinking in Systems is frequently cited as a key influence by programmers and computer scientists, as well as people working in other disciplines. The Post Growth Institute has ranked Donella Meadows 3rd in their list of the top 100 sustainability thinkers. In addition, Meadows drew on a wide range of other sources for examples and illustrations, including ecology, management, farming and demographics as well as taking several examples from one week's reading of the International Herald Tribune in 1992. The work is heavily influenced by the work of Jay Forrester and the MIT Systems Dynamics Group, whose World3 model formed the basis of analysis in Limits to Growth. After Donella Meadows' death in 2001, the book was restructured by Meadows' colleagues at the Sustainability Institute, edited by Diana Wright and finally published in 2008. The book was originally circulated as a draft in 1993 and versions of this draft circulated informally within the systems dynamics community for years. Thinking in Systems provides an introduction to systems thinking by Donella Meadows, the main author of the 1972 report The Limits to Growth, and describes some of the ideas behind the analysis used in that report.
