What are the benefits and limitations of centralization?

"The final component in building an effective organizational structure is deciding at what level in the organization decisions should be made. Centralization is the degree to which formal authority is concentrated in one area or level of the organization. In a highly centralized structure, top management makes most of the key decisions in the organization, with very little input from lower-level employees. Centralization lets top managers develop a broad view of operations and exercise tight financial controls. It can also help to reduce costs by eliminating redundancy in the organization. But centralization may also mean that lower-level personnel don’t get a chance to develop their decision-making and leadership skills and that the organization is less able to respond quickly to customer demands."
