EURAM’s Book of the Year in 2020, Hierarchy takes readers on a journey which traverses how this idea has evolved, is understood in various disciplines, and is applied in practice. Referring a wide range of sources, the book provides an inspirational introduction to understanding what is perhaps the key idea in business and management. As a fundamental organizational principle, hierarchy is everywhere. Perhaps because of its ubiquity, the significance of hierarchy has become under-analyzed in view of the growing strains on society imposed by organizational inequality. This book analyzes the advantages and disadvantages that hierarchy brings as a form of organization, providing an accessible overview of this fundamental idea within both business and society.
