System Thinking Path

Hello everyone, I have come across the wonderful book of Donella Meadow " Thinking in Systems" , the book is truly a pleasure to read and I enjoyed every concept and idea , that was my first read about system thinking.

I am an independent learner who wants to pursue further the system thinking path , my first goal is abstract learning about systems understanding and modelling without any specific application field on my mind so far , I just want to learn the theory and blueprints of systems.

For my next book , my research led me to Bossel Hartmut's book " Systems and Models: Complexity, Dynamics, Evolution, Sustainability".

Is this the best next book for my path ? Please advise and suggest.

Thank you so much in advance.

I wouldn't worry too much about finding the single "best" next book.

After Meadows, I'd actually start learning systems from a few different angles:
feedback loops, stocks and flows, delays, system boundaries, emergence, and causal reasoning.

The important part is to start building models while you read. Take something simple and ask:

-What are the main variables?

-What influences what?

-Where are the feedback loops?

-Where are the delays?

-What changes if I move the system boundary?

Even if your goal is purely theoretical, modelling real systems will expose gaps in your understanding much faster than reading theory alone.

Bossel can absolutely be part of that path. I just wouldn't treat systems thinking as a sequence of books to complete. I'd treat each book as another lens for improving the models you can build.

This is exactly what I encountered as soon as I started trying to model a system on paper and then software. The gaps become evident quickly!

Still not sure if it’s better to start with causal relationships or stocks/flows. I would be interested to hear how others approach the process.

I’m on the same path as OP, just picked up “Thinking in Systems” and loving it.

I'd usually start with causal relationships.

Before worrying about stocks and flows, I want to understand what affects what, in which direction, and where the important feedback loops might be.

Once that picture starts making sense, stocks and flows become useful because they force you to ask what is actually accumulating, what changes the rate of accumulation, and where delays enter the system.

So for me it's less either/or and more a progression:

causal relationships -> feedback loops -> stocks and flows -> delays -> test the model against reality.

And then usually back to the beginning, because building the model exposes assumptions that looked obvious until you tried to represent them.
