If you loved Thinking In Systems: A Primer, you may want to read Business Dynamics by John Sterman [1], one of the proponents and pioneers (after Jay Forrester) of systems dynamics. It's a textbook, but even so it is readable and engaging.

Systems thinking changes the way people think about solutions, often for the better (but not always). There's a tendency to think: "uh... it's the system, nothing's gonna change unless we change the _system_ per se". And that's correct. But individual actions also change systemic outputs. So. Case in point: climate change and all that...

[fun fact, I took a class with Sterman at MIT. He's fantastic, very engaging!]
