Management — The definition that includes all the other definitions in this book and which, because of that, is the most general and least precise. Its concrete, people meaning — the board of directors and all executives with the power to make decisions — is no problem, except for the not-so-little matter of where to draw the line between managers who are part of "the management" and managers who are not.
