of evolution, philosophy and linguistics upon our everyday language usage were investigated. The research documented in this book found that the human tool called language works well for describing physical objects but has difficulty producing a common understanding of the meaning of concepts - a problem not restricted to the management field. That field is simply a microcosm that exposes a much more widespread linguistic usage problem affecting our personal, religious and political lives; one that existed at the time of Plato and Aristotle and has laid hidden for millennia. This book includes a lexicon of 70 commonly used but confused or contested management terms, as well as a further 18 such project management terms, all developed by applying its definitional method. The terms include governance, power, ethics, leadership and their associated groups of terms. The book explores how disagreement can be resolved using these new clear definitions and extends this into an analysis of who ¿good¿ ethics are good for. It also incorporates a section on ¿how to speak management and actually know what you are talking about¿, written in the style of an ¿idiots guide¿ or ¿guide for dummies¿. This identifies common, everyday circumstances in which lack of agreed definitions cause avoidable confusion and provides the book¿s focus on conflict dissolution rather than on conflict resolution.
