2.1 Principles of organisational structure
Certain principles are basic to the operation of any organisation:
The work of the organisation is divided up into separate activities or tasks and particular individuals concentrate on specific tasks or activities. This enables the application of specialised knowledge and so improves organisational efficiency and effectiveness.
If an organisation’s activities are to be separated into different areas or operations, it will be necessary to ensure that the various actions are coordinated, that is, consistent with each other and working towards the same organisational objectives. This is a very important task of management. The management hierarchy or ‘chain of command’ facilitates the coordination of various departments and their activities.
Management principles of the hierarchy of authority
Management theorists (notably Henri Fayol, 1949) have, over the years, developed several principles relating to the hierarchy of authority for coordinating activities. Some of the most important are:
Unity of Command. Every person should receive orders and be accountable to one and only one superior. If people receive orders from more than one superior, conflict and confusion may well result.
- The Scalar Chain. There should be a clear line of authority from top to bottom, linking all managers at all levels.
- The Responsibility and Authority Principle. If an organisational member is allocated responsibility, then that person should also be given the necessary authority to carry out the tasks necessary – including the right to ask other people to undertake particular tasks. A manager should not be given responsibility without the necessary authority, but conversely delegation of authority implies responsibility and the need for accountability.
Span of control refers to the number of subordinates directly reporting to a manager or supervisor.
- Span of Control. There is a limit to the number of activities or people that can be supervised effectively by one person. What constitutes an effective span of control will be determined by a number of factors, including:
- the similarity of tasks/functions undertaken (the more similar, the greater the potential effective span of control)
- the proximity of the tasks to each other and to the supervisor (the closer the proximity, the greater the potential effective span of control)
- the complexity of the tasks (the more complex, the smaller the potential effective span of control)
- the direction and control needed by subordinates (the more direction and control needed, the smaller the potential effective span of control).
