1 Book
See allRead maybe 30%, skimmed most of the remaining, was not able to finish it in detail.
I suspect people who like this book will really, really like it, and people who don't, really won't.
My rating of 3 reflects my point of view coming from the engineering side. That is, I did not feel this book was overly helpful when I was working mostly as an individual contributor. I might well find a reread more useful being more on the management side.
This collection of writings provides a basic understanding of systems thinking, starting from first principles. It's referenced in a number of management and engineering books I've read, and references in blog posts are starting to appear more frequently.
One thing to understand about systems thinking is that it's really, really hard to get right in complex systems, and especially when people form an integral component of the system.
Fast read, but very little exploration useful for applying Boyd's concepts. The big take home for me: “Do your homework.”
