I’d like to recommend the Mental Model Musings website by Gene Bellinger. This systems thinking website contains a lot of interesting stories in which systems thinking and causal loop diagramming are applied to all kinds of (organisational) situations. The website also provides clear and concise introductions to systems thinking and concepts like balancing loops, self-reinforcing feedback loops, causal loop diagramming, and simulation.
Some quotes from the site:
The first rule of systems is “Don’t fight the system. Change the rules and the system will change itself!”
Buckminster Fuller said that rather than attempting to teach people the right things to do, one should design organizations such that doing the right things was simply the path of least resistance.
Energy follows the path of least resistance.
Feedback defines the path of least resistance.
