"Manager" is a general term that can be used for the person who is your boss, regardless of level. For example, a Director's boss might be the Chief Executive Officer, however the Director would refer to the CEO as his or her "manager". The hierarchy in companies is normally as follows: 1. Supervisor: Someone who manages people but without much power, for example without control of financial budgets. 2. Manager: Someone who manages people and has responsibility for things like budget, team organization, etc. 3. Director: A senior level manager, often someone who manages other managers. 4. Executive: A prefix used to indicate a higher level of authority, e.g. Executive Director. "An executive" is a broad term to describe senior level management (normally directors or above).

All I can say that managements is classified into three levels depending on the business size and authority required. The level of management determines a chain of command, the amount of authority & status enjoyed by any managerial position. The levels of management can be classified in three broad categories: 1. Top level / Administrative level 2. Middle level / Executory 3. Low level / Supervisory / Operative / First-line managers
