Sense and nonsense in systems thinking. I have withdrawn my two books on Amazon. Because my more recent Linkedin articles (listed under four titles below) are better.

This article focuses on Russell Ackoff’s fundamental ideas about the nature of systems. It reviews how Ackoff defined and classified systems in three documents that you can probably find on the internet.

• 1971 “Towards a System of Systems Concepts”.
• 1999 “Re-Creating the Corporation - A Design of Organizations for the 21st Century”
• 2003 “On The Mismatch Between Systems And Their Models”.
