I read with a measure of interest Morgen Witzel’s Management from the Masters: From Kautilya to Warren Buffett (2013). It is an eclectic compilation of “laws” of management right from the “Law of Entropy” which is actually a scientific law to Drucker’s rule which states: “The only valid purpose of a business is to create a customer.” Some other “laws” mentioned in the book are “Moore’s law”, “The Pareto Principle”, “Parkinson’s Law” and “The Peter Principle”.
