It’s an extremely good book. Not only useful to a system designer, but anyone who ever interacts with bureaucracies, or who works in organizations with more than ten people.
I concur - "Systemantics" (now "The Systems Bible") is an excellent book. I had a boss turn me onto it in the 1980s, and to this day I still quote from it, and re-read it about once a decade just to keep the lessons fresh.
