Formal vs Informal Organisation | ACCA Business Technology

Every organisation needs a clear arrangement of roles, responsibilities, and authority to achieve its objectives effectively. At the same time, employees naturally develop relationships and communication channels that exist beyond official reporting lines. These two aspects form the basis of formal and informal organisations. 

In ACCA Business Technology, understanding organisational structures and design helps students analyse how businesses coordinate activities, make decisions, manage employees, and adapt to changing business environments. Different organisational structures influence communication, control, efficiency, and overall business performance.

Organisational Structures & Design Introduction

Organisational structures provide the framework for how tasks, roles, and authority are formally and informally arranged within a business. Understanding these structures is vital for efficient operations, effective management, and achieving strategic goals. This guide explores the various types of organisational structures and key concepts that influence their design and functionality.

Formal Organisation

A Formal Organisation has a planned structure, designed by management to achieve specific goals. It acts as a skeleton, providing a rigid, stable frame for the company with a documented framework. Power and authority are derived from one's position, not the person themselves.

Building a Formal Structure: Three-Step Process

1. Specialisation (Labor Division): Dividing complex tasks into smaller, repeatable tasks. Example: Hotel guest check-in.

2. Departmentalisation: Grouping similar tasks into dedicated departments. Examples: Marketing Department, Sales Department, Finance Department.

3. Coordination: Ensuring different departments work together effectively. Mechanisms include Standard Operating Procedures (SOPs), manuals, and clear reporting lines. (Memory Tip: Coordination is "the glue that makes departments work together.")

Informal Organisation

Informal organisations are spontaneous networks and relations among employees that are not formally planned or structured. They form spontaneously, allowing for fast communication, and are governed by group norms. Communication does not follow a fixed direction. (Memory Tip: This unplanned communication channel is called the Grapevine Network.)

• Advantages

• Reduced Bureaucracy: Circumvents formal processes for quick problem-solving.

• Fast Knowledge Sharing: Unwritten tips and know-how are shared quickly.

• Emotional Support: Fosters a sense of belonging and reduces stress.

• Disadvantages

• Disregard for Protocols: Informal groups may ignore formal rules.

• Social Exclusion: Groups can exclude or bully other employees.

• Resistance to Change: If an informal leader dislikes a management decision, they can convince their entire team to resist its implementation.

Formal vs. Informal Organisation: Key Differences

Types of Organisational Structures

Businesses adopt different organisational structures depending on their sise, objectives, products, and operational complexity. The chosen structure affects communication, decision-making, accountability, and overall performance. 

Understanding these structures helps explain how businesses organise resources and coordinate activities effectively.

1. Entrepreneurial Structure (Simple Structure)

This is the simplest structure, built around a single owner or entrepreneur, with all other employees reporting directly to them.

• Suitable For: Small businesses.

• Advantages: Fast decision-making, close bond with employees, good control.

• Disadvantages: Not suitable for large businesses, limited career growth.

2. Functional Structure

Organises departments based on functions (e.g., HR, Sales, IT), each managed by a functional head reporting to a CEO.

• Suitable For: Small to medium enterprises.

• Advantages: Specialisation, career growth within a specific function, standardisation of work processes.

• Disadvantages: Departmental conflicts (silos), not suitable for very large or highly diversified organisations.

3. Divisional Structure

Creates separate, semi-autonomous divisions, each operating like a separate business with its own functional departments. Divisions can be Product-wise, Area-wise, or Customer-wise.

• Suitable For: Large, diversified organisations.

• Advantages: Easy expansion and diversification, managerial training, top-level focus on strategic decisions, and promotes overall growth.

• Disadvantages: Duplication of resources (higher costs, reduced efficiency), difficulty in allocating central costs.

4. Matrix Structure

A hybrid structure combining elements of divisional and functional structures. Employees report to both a functional manager and a project/divisional manager. Functional departments provide resources across multiple projects.

• Advantages: Cost efficiency (avoids duplication), better service through shared expertise, fosters teamwork.

• Disadvantages: Dual reporting (can create confusion), high potential for conflicts, and time wasted in meetings.

Boundaryless Structures (Modern Structures)

These modern forms aim to break down traditional organisational boundaries.

1. Hollow Structure

Divides work into core vs. non-core activities. Core activities are performed in-house, while non-core activities are outsourced to external firms. Example: An accounting business outsourcing IT work.

2. Virtual Organisation

Characterised by minimum physical presence and operations based on a network of independent entities or individuals. It functions primarily through communication technologies, with almost no in-house staff or physical offices. Example: Early somato, connecting restaurants and customers without owning physical infrastructure.

3. Modular Organisation

Breaks down a large product into distinct components (modules). Some components are produced in-house, others outsourced. The organisation then assembles these into a final product under its own brand. (Memory Tip: "Modular" means "Modules," or "Components.") Example: Car manufacturing outsourcing an engine.

Key Organisational Concepts

1. Scalar Chain vs. Span of Control

• Scalar Chain: The vertical line of authority from the top level to the bottom level, representing the number of levels in the hierarchy.

• Span of Control: The number of employees a manager monitors or to whom employees report. Types include Narrow Span of Control (few employees) and Wide Span of Control (many employees).

Factors Affecting Span of Control

• Manager's Skills: Skilled managers handle wider spans.

• Employee Location: Different locations need narrower span; same allows wider.

• Employee Sincerity: Sincere employees permit wider span; insincere require a narrower.

• Nature of Work: Routine tasks allow wider span; complicated tasks require a narrower.

2. Tall vs. Flat Structures

3. Levels of Management Planning

• Strategic Level (Top Level): By senior managers. Long-term decisions (3-5+ years) impacting the entire organisation. Example: Global expansion.

• Tactical Level (Middle Level): By middle-level management. Mid-term decisions (1-2 years). Example: Sales manager planning a 20% sales increase.

• Operational Level (Bottom Level): By junior managers. Short-term, day-to-day decisions. Example: Monthly recruitment targets.

4. Centralisation vs. Decentralisation

5. Shared Service Approach

Centralises certain support functions (e.g., IT, HR, Finance) into a single unit to serve all organisational divisions, even if other functions are decentralised. Example: Multiple company divisions sharing a single IT or HR department.

6. Outsourcing vs. Offshoring
