In and of itself managerial decentralization is neither desirable nor undesirable. We must apply certain criteria in order to evaluate it. One such criterion is economic efficiency: At what point in the management hierarchy and by what individual is a particular decision made most efficiently? Is a particular function exercised or a service performed more cheaply if it is "centralized" or "decentralized"? It is impossible to say in general that either centralization or decentralization is more efficient.
