Principles of Organisational Design (AQA A Level Business): Revision Note

Introduction to organisation structures

• Organisational structures show the reporting relationships, roles and responsibilities of employees in a business

• Businesses must determine what the best structure is for them to effectively implement their ideas and achieve their objectives

  • They should consider how the structure may affect the management and effectiveness of operations and communications

  • A well-designed organisational structure helps to promote clarity, efficiency and accountability

Key terminology used in organisational design

Hierarchy

• A hierarchy refers to the levels of authority within an organisation

  • It describes the ranking of positions from top to bottom

  • The higher the position in the hierarchy, the more authority and power it holds

  • The hierarchy usually includes top-level management, middle-level management and lower-level employees

Bureaucracy

• A bureaucracy is an organisation with many levels of authority

  • This makes decision-making and communication somewhat time-consuming

Centralised and decentralised structures

• In a centralised structure, decision-making authority is concentrated at the top of the organisation, with senior management making most of the decisions

• In a decentralised structure, decision-making authority is distributed throughout the organisation, with lower-level employees having more delegated decision-making power

  • Decentralisation can promote flexibility and innovation, while centralisation can promote consistency and control

Chain of command

• The chain of command is the formal line of authority that flows down from the top management to lower-level employees

  • It defines who reports to whom

  • The chain of command helps to establish a clear communication channel and helps to maintain accountability within the organisation

Span of control and levels of hierarchy

• The span of control is the number of employees that a manager or supervisor effectively manages

• The span of control affects how closely employees are supervised and how quickly decisions can be made

  • The appropriate span of control depends on the complexity of the work, the experience of the employees and the management style of the business

• A wide span of control reduces the number of managers needed, lowering costs

  • But each manager has less time to devote to each employee, which can reduce the quality of support and oversight

• A narrow span of control allows closer supervision and stronger communication between manager and team

  • But requires more managers, increasing costs and potentially slowing decision-making

• Levels of hierarchy refers to the number of layers of authority within an organisational structure, from the most senior (e.g. the chief executive) to the most junior (e.g. frontline workers)

• Levels of hierarchy determine how far decisions must travel up and down the organisation, affecting the speed and quality of communication

  • Tall structures have many levels of hierarchy

    • These give employees a clear chain of command and defined career progression

    • They can slow decision-making and create distance between senior management and frontline staff

  • Flat structures have fewer levels of hierarchy

    • They allow for faster decision-making and more direct communication between managers and employees

    • They can increase individual workloads and limit career progression opportunities

• The number of levels is directly linked to span of control

  • A business with wide spans of control needs fewer levels of hierarchy to manage the same number of employees

Tall and flat structures

• Businesses typically design their organisations in one of two ways:

  • Tall organisational structure

  • Flat organisational structure

1. Tall organisational structures

• Tall or vertical structures have multiple levels of management, a more centralised decision-making process and a long chain of command

• Spans of control are usually narrow, and managers exert significant control

• Tall structures are common in large organisations with complex operations, e.g. government agencies and universities

What it looks like	Advantages	Disadvantages
	Provides a clear hierarchy of authority and defined roles and responsibilities Promotes specialisation and expertise within each department or function Offers opportunities for career advancement and promotion within the organisation All of the above increase efficiency and motivation	Can create communication barriers between the upper and lower levels of the hierarchy Decision-making can be slow as information must pass through multiple layers of management Can lead to bureaucracy and excessive levels of management All of the above reduce efficiency and motivation

2. Flat organisational structures

• Flat or horizontal structures have fewer levels of management, a decentralised decision-making process and a short chain of command

• Spans of control are often wide, and employees have some level of autonomy

• Flat structures are common in small organisations or start-ups

What it looks like	Advantages	Disadvantages
	Promotes a culture of collaboration and open communication Decision-making can be faster and more efficient Encourages creativity and innovation, as employees have more autonomy and flexibility All of the above increase efficiency and motivation	Can lead to role ambiguity and a lack of a clear hierarchy May not provide clear opportunities for career advancement or promotion May require employees to take on multiple roles and responsibilities, leading to burnout and staff overwhelm All of the above reduce efficiency and motivation
