The author argues that no person can be an ideal “book” leader, and ignoring this fact leads to loss of productivity and a drop in company profits. Adizes presents a new approach to management: it is necessary to recognize that management is too complex a process to hope that one person can perform all management roles equally successfully. Each role requires a special style, that is, a certain behavior in similar situations. The roles that managers have to play are in conflict. Therefore, a person can play each of these roles at different points in life, but will never be able to play them all at the same time. The book is written to help you identify management mistakes and determine possible ways to correct the consequences of these mistakes.
