In any business organisation there are a series of management positions from the top to the bottom. The amount of authority and status of any managerial position is determined by the level of management. Broadly, there are three levels of management -- top, middle and lower. In the top management level we have the board of directors, chief executives and the departmental heads. These people provide leadership to the organisation and establish overall long-term goals. The middle level management consists of the departmental managers who receive orders, suggestions and decisions from the top management and convey them to the lower level for implementation. The lower level management is responsible for day-to-day working of the organisations.
