Every business needs a way to divide work, assign responsibilities and coordinate employees. A formal organisation establishes official roles, authority and reporting lines, while an informal organisation develops through employees' social relationships and everyday interactions. Both influence how information flows, how decisions are made and how employees work together.
For ACCA BT Knowledge Level revision, understanding these concepts helps you recognise organisational relationships and apply them to business situations. You can use these notes alongside PW ACCA batches, study resources, revision materials and exam-focused learning support to strengthen your preparation for the Business and Technology examination.
A formal organisation is a structure that management plans and designs to achieve specific business objectives. It provides an official framework that explains how work is divided, how departments are organised and who has authority to make decisions.
The formal structure can be understood through three main processes:
Specialisation: Dividing complex work into smaller, specific tasks. For example, a hotel may assign check-ins to reception staff and room cleaning to housekeeping staff.
Departmentalisation: Grouping related tasks into departments, such as Finance, Marketing and Human Resources.
Coordination: Ensuring that individuals and departments work towards common objectives through procedures, manuals and reporting lines.
Defined authority: Power is associated with an official position rather than the individual holding it.
Clear responsibilities: Employees understand their assigned duties.
Established communication channels: Information follows recognised reporting lines.
Documented procedures: Rules and standard operating procedures guide work.
Goal-oriented design: The structure is created to help the organisation achieve its objectives.
For example, in a company, a sales executive may report to a sales manager, who reports to the head of sales. This reporting relationship forms part of the formal organisational structure.
An informal organisation consists of the social networks and relationships that develop naturally among employees. Unlike a formal structure, it is not deliberately designed by management and does not depend on official job titles or documented reporting lines.
Informal relationships can influence communication, employee morale, knowledge sharing and how people respond to workplace decisions.
The grapevine is an informal communication channel through which employees exchange information outside official communication systems. It can spread information quickly, but it may also circulate rumours or inaccurate details.
For example, employees might hear about a possible change in working hours through conversations with colleagues before management issues a formal announcement.
Informal relationships can support employees and improve communication, but they may also create challenges when group behaviour conflicts with organisational policies.

Advantages |
Disadvantages |
|
Faster sharing of information |
Rumours and inaccurate information may spread |
|
Sharing practical knowledge and experience |
Informal leaders may encourage resistance to change |
|
Emotional support and a sense of belonging |
Cliques can lead to exclusion or bullying |
|
Quicker resolution of everyday problems |
Employees may bypass official procedures or safety rules |
Understanding the difference between formal and informal organisations is important for ACCA BT organisational relationships. Both can exist within the same business and influence how employees communicate and complete their work.

A business does not have to choose between the two. Formal systems provide accountability and clarity, while informal relationships can help employees exchange knowledge and build connections.
A formal organisational structure in business determines how authority, responsibilities and reporting relationships are arranged. The appropriate structure depends on factors such as business size, activities, products and the need for coordination.
This structure is commonly associated with small businesses and start-ups. The owner or founder makes many key decisions, allowing the organisation to respond quickly. However, employees may have limited opportunities for promotion as the business grows.
Employees are grouped according to their area of expertise, such as Finance, Marketing, Operations or Human Resources.
Advantages:
Encourages specialisation and the development of expertise.
Makes it easier to manage employees performing similar tasks.
Disadvantages:
Departments may become isolated from one another.
Coordination between functions can become difficult.
A business may organise its operations by product, geographical area or customer group. This is often useful for large or diversified organisations.
Advantages:
Allows divisions to focus on particular markets or products.
Makes responsibility for divisional performance easier to identify.
Disadvantages:
Different divisions may duplicate resources and activities.
Operating costs may increase.
A matrix structure combines functional departments with project teams. An employee may report to both a functional manager and a project manager.
Advantages:
Encourages collaboration across departments.
Allows employees with different skills to work together on projects.
Disadvantages:
Dual reporting can create confusion over priorities.
Conflicts may arise between functional and project managers.
Boundaryless organisational models use flexible arrangements that reduce reliance on traditional internal structures.

The scalar chain and span of control help explain how authority and supervision operate within an organisation. They are also useful for understanding the difference between tall and flat structures.
Scalar chain: The vertical line of authority from senior management to lower levels.
Span of control: The number of employees who report directly to a manager.

Neither structure is automatically suitable for every business. The choice depends on the level of supervision required, the nature of the work and the experience of employees.
Centralisation and decentralisation describe where decision-making authority is held within an organisation. The choice affects consistency, employee responsibility and the speed of local decisions.

Some businesses also use shared services, where functions such as Finance or Human Resources are brought together in a central unit to serve different departments or divisions.
Outsourcing and offshoring are related business decisions, but they refer to different things. The key distinction is whether an activity is transferred to an external provider or moved to another country.
Outsourcing: Hiring an external organisation to perform an activity, often so the business can focus on its core activities.
Offshoring: Moving an activity or operation to another country. The activity may remain within the same organisation.
For example, a company that hires an outside provider to manage payroll is outsourcing. If it moves its own payroll team to an office in another country, it is offshoring.
