Thinking in Systems: A Primer Book review by Deane Barker • September 17, 2019 • tags: systems • Lovely introduction to general systems theory. You come to understand that a “system” can be almost anything, defined by inputs, outputs, rules, buffers, etc. The book discussed how systems can be effected and changed over time. Exactly what I was looking for. Book Info Author Donella H. Meadows Year 2008 Pages 240 Acquired June 18, 2022 I have read this book. According to my records, I completed it on September 17, 2019.
