A manager cannot extract the best performance from employees by threatening them with termination or offering financial rewards for high productivity. Rather, employees must come to want to do a good job for its own sake. One of the best ways for a manager to achieve this is to delegate responsibility to them, especially for decisions that previously had to be made by the manager. Which one of the following propositions is best illustrated by the situation described in the passage? ["Increased responsibility can improve a person's sense of how power should be used.", 'People who carry out decisions are in the best position to determine what those decisions should be.', "In some cases one's effectiveness in a particular role can be enhanced by a partial relinquishing of control.", 'Business works best by harnessing the self-interest of individuals to benefit the company as a whole.']
