What are the uses (purposes) of an organisation chart?
An organisation chart is used to show how a business is arranged and who is responsible for what.

What are the limitations of an organisation chart?
An organisation chart shows only the formal arrangement of a business, so it has some limits.
- Informal links: it does not show friendships and unofficial contacts between workers.
- Out of date: it becomes wrong if it is not changed when the structure changes.
- Limited detail: it does not show how much authority each post really carries.
How is a simple organisation chart arranged?
A simple organisation chart places the highest officer at the top and the departments in boxes below.
How do you read an organisation chart?
To read an organisation chart, start at the top box and follow the lines downwards.
- Start at the top box. It holds the highest authority, such as the Board or Managing Director.
- Follow the vertical lines downwards. They show the line of authority and who reports to whom.
- Note that boxes on the same level have the same rank.
- Count the boxes joined directly under one manager. This gives that manager’s span of control.
- Read the titles in the boxes to know each position and department.
What are the levels of management shown on a chart?
There are three levels of management: top, middle and lower.
- Top management: the Board of Directors and the Managing Director, who set the aims and policies.
- Middle management: departmental managers, who carry out the policies in their departments.
- Lower management: supervisors and foremen, who direct the daily work of the workers.
