Stephen Covey, author of the international bestseller “The Seven Habits of Highly Effective People,” wrote his new book for company leaders who are faced with the pressing need to show concrete results of their work in conditions of uncertainty. Economic instability, a changing market situation, the rapid development of new technologies - the company leader cannot take into account all the uncertainties of the future and turn them into a set of certainties. In such difficult situations, you can rely on basic, key rules and principles of action. They do not change and will never fail. Stephen Covey formulated these rules as follows: ensure excellent performance of your priority tasks; move at the speed of trust; achieve more with fewer resources; reduce fear. The author states: “Teams that adhere to these rules are always prepared for difficult times and never give up.” The book devotes a separate chapter to each of the four rules and proposes a plan that will help apply the author’s advice in practice. The book is intended for company owners, top and middle managers, as well as anyone interested in the long-term development of their company.
