A contrarian challenge to the status quo, this book vigorously champions healthy skepticism in management theory and practice. Several common management maxims -- often taken for granted as truisms -- are examined and debunked with evidence-based arguments. An introductory chapter provides a brief perspective of maxims in the English language, and presents a preview of the rest of the book. Each of the next eleven chapters contains in-depth, evidence-based rationale that disproves the certainty of a commonly believed maxim.
