Tall vs Flat Organisational Structures
Learn how tall and flat organisational structures differ in management levels, span of control, communication and decision-making, with an A Level Business example.
A tall organisational structure has many levels of management between senior leaders and employees. A flat organisational structure has fewer levels. The main difference is how many layers a decision passes through and how many people each manager directly supervises.
How do they work?
In a tall structure, managers usually have a narrow span of control: each supervises a relatively small number of employees. There is a longer chain of command, meaning more levels through which instructions and decisions may pass. This can provide close supervision and clearer promotion routes, but decisions and communication may take longer. More management roles can also increase costs.
In a flat structure, managers usually have a wide span of control: each supervises more employees. With fewer levels in the chain of command, employees may be able to communicate with senior managers more directly, and decisions may be made faster. Employees may also receive more delegation, where a manager gives them responsibility for tasks or decisions. However, managers may be stretched, and employees may receive less direct support.
For example, a business with several layers of regional and local managers might require a shop manager to seek approval through multiple levels before changing a staffing arrangement. A flatter business might let that manager decide locally. That could be quicker, but the business would need to trust the manager's judgement and provide appropriate guidance.
Exam mistake to avoid: do not claim that flat is always better. The best structure depends on factors such as the size of the business, the skills of its employees and how much control senior managers need. Explain the likely effect on the particular business in the question.
