Organisational Structure

Organisational structure is the way a business arranges its roles, responsibilities, authority and reporting relationships. It shows who reports to whom, how decisions are made and how work is coordinated across the organisation. 

A clear structure matters because employees need to understand their role, their manager, their responsibilities and the level of authority they have. If the structure is unclear, communication may be poor, decisions may be duplicated and accountability may be weak. 

One important feature is hierarchy. This refers to the levels of authority within a business, from senior managers to middle managers, supervisors and employees. The number of levels affects communication, control and decision-making speed. 

The chain of command is the formal line of authority through which instructions and communication pass. A long chain of command may support control, but it can slow communication and distort messages as they move through the organisation. 

Span of control means the number of subordinates reporting directly to a manager. A narrow span of control means a manager supervises fewer people. A wide span of control means a manager supervises more people. 

A tall organisational structure has many levels of hierarchy. It is often linked with narrow spans of control, clear reporting lines and closer supervision. This can be useful in large, complex or risk-sensitive organisations where control and consistency matter. 

However, tall structures can create problems. Communication may be slower because messages pass through many levels. Decision making may be centralised and bureaucratic. Employees lower down the hierarchy may feel less empowered, which can reduce motivation and slow innovation. 

A flat organisational structure has fewer levels of hierarchy. It is often linked with wider spans of control, shorter chains of command and greater employee autonomy. This can support faster communication and decision making. Flat structures can also improve motivation because employees may feel trusted and empowered. They may have more opportunity to contribute ideas, solve problems and take responsibility for their work.

However, flat structures are not always better. Managers may become overstretched if their span of control is too wide. Employees may receive less supervision and support. Roles can become unclear if authority and accountability are not well defined. 

A matrix structure combines functional departments with project, product or regional teams. For example, an employee may report to a marketing manager but also work on a product launch team led by a project manager. 

Matrix structures can improve flexibility and collaboration because employees from different functions can share expertise. This can be useful for innovation, product development, major projects or multinational businesses that need cross-functional coordination. 

However, matrix structures can create confusion. Employees may have two managers with different priorities. This can lead to conflict, slower decisions and unclear accountability unless roles, communication and leadership are managed carefully. 

Organisational structure also links to centralisation and decentralisation. A centralised structure keeps decision making near the top of the business. A decentralised structure gives more authority to managers or employees closer to customers, operations or local markets. 

Businesses may change structure through restructuring or delayering. Delayering removes levels of management to create a flatter structure. This may reduce costs and speed up communication, but it can increase workloads and damage morale if employees fear job losses. 

The best structure depends on context. A small start-up may benefit from a flat structure because it needs speed and flexibility. A large public service organisation may need a taller structure for control and accountability. A multinational business may use matrix features to coordinate products, functions and regions. 

Overall, organisational structure affects communication, motivation, control, accountability and competitiveness. Strong exam answers should not simply state that flat or tall is better. They should explain how the structure affects the specific business and judge whether the benefits outweigh the trade-offs.
