Communication
Structure determines how information moves vertically between levels and horizontally between departments or teams. Long or unclear communication routes can slow decisions or distort messages.

7.1 Organisational structure
An organisational structure determines how authority, responsibility, communication and accountability are arranged. The most suitable structure depends on what the business is trying to achieve, how large and complex it is, the skills of its employees and the environment in which it operates.

What you need to know
You should be able to interpret organisational charts, compare structures and explain how design affects communication, control, motivation, speed of decision-making and the achievement of business objectives. In evaluation questions, avoid assuming that a flat, matrix or decentralised structure is automatically superior. The best choice depends on the business and the task.

High-grade habit: always connect a structural feature to a business consequence. For example, a wider span of control may reduce management costs, but it may also reduce supervision and require more capable, trusted employees.

7.1.1
Relationship between business objectives and structure
What is an organisational structure?
Organisational structureThe way a business is arranged so that its activities can be carried out and coordinated.
An organisational structure shows how work is divided and coordinated. It normally identifies the routes through which communication travels, who has authority, who is responsible for particular tasks, the roles and titles of employees, and who is accountable to whom. The structure therefore influences both everyday operations and the ability of the organisation to achieve its long-term objectives.
Authority
Authority is the power to make decisions and direct the actions of others. A structure indicates where this power is located and how far it is passed down.
Responsibility
Responsibility is the duty to complete a task and answer for the outcome. Managers remain responsible for work even when they delegate authority to others.
Accountability
Accountability means being answerable for performance. A clear structure makes it easier to identify who must explain results and who reports to whom.
AuthorityThe power to control situations or make decisions affecting the actions of others.
ResponsibilityThe duty to complete a task and be answerable for the results.
The case for flexible organisational structures
There is no single organisational structure that is suitable for every business. A structure is a management tool and should fit the organisation's circumstances. A flexible structure can change as customer needs, technology, competition and the size of the business change.
- Continual adaptation: roles, teams and reporting arrangements can change when the organisation's needs change.
- Customer focus: employees can be reorganised into teams that respond quickly to different customer requirements.
- Flexible staffing: consultants, temporary workers and part-time employees can provide specialist skills or help manage peaks in demand.
- Employee adaptability: people become more accustomed to change and may be more willing to take on new tasks or responsibilities.
Why structure should reflect business needs
Size of the business
As a business grows, one manager cannot control every employee or make every decision. More authority may need to be passed to people lower in the hierarchy, while specialist managers and departments may be added.
Nature of the product
A business supplying very different products may create separate divisions so that each can use appropriate skills, production methods and marketing approaches.
Business objectives
A business aiming for rapid growth, low costs, innovation or excellent customer service may require different reporting relationships and degrees of employee authority.
External environment
New technology, government policy, competitor behaviour and changing consumer tastes can make an existing structure too slow or too expensive and may force redesign.
Structure, growth and development
A structure should support growth rather than become a barrier to it. As an organisation expands, its chain of command may lengthen and more layers may be added. However, too many layers can make the organisation slow, costly and difficult to coordinate. Businesses may therefore flatten their structures so that communication is quicker and senior managers can obtain information from lower levels more easily.
Application: a business entering new countries may need local divisions because customers and regulations differ. A small single-site business may not need that complexity. The same structural design can therefore be efficient in one context and wasteful in another.
Encouraging intrapreneurship
IntrapreneurshipEmployees developing and pursuing new ideas inside an existing organisation.
EmpowermentGiving employees greater control over their work and greater authority to make decisions.
Businesses that want innovation may deliberately design a structure that gives employees freedom, resources and authority. Heavy supervision can discourage experimentation, whereas wider spans of control, delegation and project teams may create room for employees to test ideas. This only works when managers trust staff and when employees have the skills and motivation to use their freedom responsibly.
Evaluation: an innovation-focused business may benefit from a loose, flexible structure, but a business where errors create major safety or legal risks may require tighter control and clearer procedures.
7.1.2
Types of structure
Levels of hierarchy
Levels of hierarchyThe number of layers of authority between the top of the organisation and employees at lower levels.
A tall or narrow structure has many layers. A flat structure has fewer layers. Tall structures often permit close supervision, but communication has to pass through more people. Flat structures usually involve wider spans of control and give employees greater independence.
Tall / narrow structure
Chief executive
Directors
Managers
Supervisors
Employees
Typical effect: more layers, narrower spans, closer control and a longer chain of command.
Flat structure
Chief executive
Managers / team leaders
Employees
Typical effect: fewer layers, wider spans, faster communication and greater employee independence.
Chain of command
Chain of commandThe line of authority and communication through the organisation.
A long chain of command can make communication slower and increase the risk that a message is altered or misunderstood as it passes through levels. A shorter chain can improve speed, but it normally means managers supervise more people and must rely more heavily on delegation and trust.
Span of control
Span of controlThe number of subordinates who report directly to a manager.
Narrow span
- Allows closer supervision.
- May suit complex work or inexperienced employees.
- Often associated with more hierarchy.
- Can raise management costs.
- May restrict employee independence.
- Can lengthen communication routes.
Wide span
- Can reduce management layers and costs.
- Encourages independence and delegation.
- Can speed communication.
- Managers may become overloaded.
- Close supervision becomes difficult.
- Requires capable and trusted employees.
Worked span-of-control example
A department has 48 employees reporting directly to six supervisors. The average span of control is:
48 ÷ 6 = 8 employees per supervisor.
If two supervisory posts are removed and the same 48 employees are shared among four supervisors, the average span becomes 12. This may lower management costs but increases each supervisor's workload.
Responsibility, authority, delegation and centralisation
These ideas are closely related to structure. Wider spans often require managers to delegate more authority. A centralised organisation keeps most important decision-making near the top, while a decentralised organisation passes more power to lower levels, branches or divisions. These choices affect motivation, speed, control and consistency.
Informal organisational structures
An informal structure does not rely heavily on a visible hierarchy. It can suit groups of highly trained professionals who are capable of organising much of their work independently and who mainly need administrative support. Its strengths are autonomy and flexibility; its weakness is the possibility of poor coordination and weak control.
Hierarchical structures
In a hierarchical structure, every employee except the most senior person is subordinate to someone else. Roles and reporting relationships are clearly defined and departments often operate according to established procedures.
| Potential advantages | Potential disadvantages |
|---|---|
| Authority and responsibility are clear. | Responses to customers can be slow. |
| Employees can see possible promotion routes. | Horizontal communication between departments may be weak. |
| Control can be strong and procedures consistent. | Senior managers may become remote from customers and junior staff. |
| A flatter hierarchy can combine clarity with delegation. | Wide spans can overload managers if delayering goes too far. |
Functional structures
A functional structure groups employees according to specialist business functions such as marketing, finance, operations and human resources. This allows expertise to develop and can create strong professional standards. However, departments can become inward-looking, compete for resources or pursue departmental goals rather than the objectives of the whole organisation.
Finance
Specialists manage accounting, budgets, finance and financial control.
Human resources
Specialists manage recruitment, training, employee relations and workforce policies.
Operations
Specialists focus on production, quality, capacity and efficiency.
Marketing
Specialists focus on customers, market research, promotion, pricing and sales.
Structures based on geography or products
Large businesses may organise around regions or countries so that local managers can respond to differences in consumers, laws and market conditions. Others organise around products or brands because different products require distinct skills, processes and customer knowledge. Divisional structures can improve focus and speed, but they may duplicate functions and make coordination across the organisation harder.
Matrix structures
Matrix organisational structureA structure in which employees from different functions work together in teams or projects while retaining links to their normal departments.
Project / function
Marketing
Operations
Finance
Project A
Marketing specialist
Operations specialist
Finance specialist
Project B
Marketing specialist
Operations specialist
Finance specialist
Matrix structures are task-oriented. A project manager can draw on the specialists needed for a specific project without permanently reorganising the whole business. This can improve flexibility, innovation and customer responsiveness.
| Advantages of matrix structures | Disadvantages of matrix structures |
|---|---|
| Focuses people on a clearly defined task or project. | Employees may have two managers and divided loyalties. |
| Uses specialist talent from across the organisation. | Conflict may arise between project and functional managers. |
| Can motivate employees with varied and challenging work. | Coordination and support can be expensive. |
| Can respond flexibly to changing customer needs. | Priorities and accountability may be unclear unless carefully managed. |
How structures change as businesses grow
More hierarchy
Growth can make existing managers' spans too wide. Additional managers or supervisory layers may be introduced to control workloads.
New departments or divisions
New products or markets may require specialist employees, different procedures or more local decision-making.
Greater delegation
Founders and senior managers can no longer make every decision, so authority must move down the organisation.
Delayering
If growth creates bureaucracy, the business may later remove layers to reduce cost and speed communication.
Evaluation: growth does not automatically mean “more layers”. Modern firms may grow using project teams, digital communication and decentralised units instead. The appropriate structure depends on complexity, skills and control needs.
7.1.3
Delegation and accountability
DelegationThe passing of authority from a manager to a subordinate so that the subordinate can make specified decisions or perform specified tasks.
AccountabilityBeing answerable for performance and outcomes.
Authority moves downwardManagers give employees the power to make agreed decisions.
⇄Accountability moves upwardEmployees report results to managers, while the manager retains overall responsibility.
Delegation is especially important as businesses become larger. It reduces the burden on senior managers and can allow decisions to be made closer to customers and operations. However, delegation must be clear: the employee needs to know which decisions they can make, what resources they can use and what results are expected.
The process of effective delegation
1. Plan and prepare
Define the objective, the task, the limits of authority and the standard expected. Select a suitable employee.
2. Train both sides
Managers may need to learn how to delegate effectively; employees may need technical or decision-making skills.
3. Build trust
The manager must trust the employee to act, and the employee must trust that the manager will support reasonable decisions rather than constantly interfere.
4. Provide support
Complex tasks may need regular meetings, coaching, information or further training without removing the employee's authority.
Impact of delegation on the business
Delegation can influence more than employee relations. It can change operations by supporting self-managed teams, improve marketing by allowing customer-facing employees to respond quickly, and encourage innovation because employees have more freedom to act. Although training and support can raise costs at first, improved motivation and productivity may reduce unit costs over time.
| Advantages | Disadvantages / risks |
|---|---|
| Can increase motivation, productivity and retention. | Training and support can be expensive. |
| Can improve speed and quality of decisions made close to customers. | Some managers may be unwilling or unable to give up control. |
| Reduces senior managers' workloads so they can focus on strategic issues. | Employees may make poor decisions if skills or information are inadequate. |
| Develops junior employees for future promotion. | Delegation is usually unsuitable for an urgent crisis requiring rapid senior decisions. |
Delegation and motivation
Delegation can make work more challenging and meaningful. In Maslow's terms, greater authority and recognition can help employees satisfy esteem needs. In Herzberg's theory, achievement, recognition and the work itself are motivators, so interesting delegated tasks may increase satisfaction and performance.
Exam distinction: managers delegate authority, not their ultimate responsibility. If the subordinate performs badly, the manager must still answer for the decision to delegate and for the system of control used.
7.1.4
Control, authority and trust
Spans of control and levels of hierarchy
Span of control and hierarchy are usually inversely related. If the same workforce is organised into fewer layers, each remaining manager normally has more people to supervise. If more layers are added, spans tend to narrow.
Tall structure + narrow spans
Often associated with close control, more supervision and possibly a more authoritarian leadership style. It may suit less experienced employees or complex tasks that require monitoring.
Flat structure + wide spans
Often associated with delegation, skilled employees, self-managed teams and more democratic leadership. It can reduce bureaucracy but depends on trust and capability.
Delayering
DelayeringRemoving one or more levels of hierarchy from an organisation.
Remove management layersFewer levels
→Wider spans of controlMore direct reports per manager
→More authority lower downGreater need for delegation and trust
Potential benefits of delayering
- Reduces management wage costs.
- Shortens the chain of command.
- Can improve communication speed and customer responsiveness.
- Can make junior jobs richer and more motivating.
Potential problems
- Redundancies can damage job security and morale.
- Remaining managers can become overloaded.
- Important organisational knowledge may be lost.
- Succession planning can suffer if potential future senior managers leave.
Knowledge managementThe process of identifying, retaining and effectively using the knowledge held within an organisation.
Labour productivityThe amount of output produced in relation to the labour used. Structural changes that improve motivation, skills or decision-making may raise productivity.
Authority is not the same as responsibility
A manager can grant an employee authority to make a decision, but the manager remains responsible for the outcome. If a junior employee makes a poor decision because they were insufficiently trained or the limits of authority were unclear, the senior manager cannot simply transfer responsibility to that employee.
The conflict between control and trust
Delegation requires managers to give up some control. If a manager delegates a decision but then constantly monitors and overrides the employee, the employee does not truly have independent authority. This can waste management time and damage motivation.
Trust is more likely when…
- the culture supports delegation
- leadership encourages participation
- employees are skilled and prepared
- managers have been trained to delegate
- expectations and limits are clear
Control is more likely when…
- tasks are high risk or tightly regulated
- employees are inexperienced
- managers hold a Theory X view
- past performance has reduced trust
- the organisation is dealing with a crisis
Evaluation: control and trust are not complete opposites. A business can give employees genuine authority while still using targets, reporting systems and reviews to protect quality and corporate objectives.
7.1.5
Centralisation and decentralisation
Centralised organisationAn organisation in which senior managers retain most decision-making power.
Decentralised organisationAn organisation in which more decision-making power is given to employees, branches, departments or divisions lower in the structure.
Centralisation
- Can provide consistency across the organisation.
- Can allow experienced senior managers to retain control.
- Can support bulk purchasing and economies of scale.
- Can suit lower-skilled work or decisions with major organisation-wide consequences.
- Senior managers can become overloaded.
- Local decisions may be slow or poorly adapted to customer needs.
- Junior employees may have less opportunity to develop.
↔
Decentralisation
- Can improve motivation through achievement and recognition.
- Reduces senior managers' operational workload.
- Develops junior managers for future promotion.
- Local employees may understand customers and operating conditions better.
- Decisions may become inconsistent between locations.
- Requires strong communication and clear corporate objectives.
- May lose some purchasing or coordination economies.
Why some businesses decentralise
Decentralisation can be particularly useful for large, multi-site or multinational businesses because local managers may have better knowledge of customers, employees and local market conditions. It also supports motivation and management development by giving junior employees real responsibility.
Why some businesses remain centralised
Centralisation can still be efficient where senior managers possess much greater expertise, where employees are relatively low-skilled, where consistent standards are critical, or where purchasing and other decisions gain significant economies by being combined. It may also reflect the preferred leadership style of senior managers.
Do not write: “decentralisation is always better.” A business with many skilled local managers and diverse markets may benefit from it; a business requiring strict uniformity, safety or central purchasing may have stronger reasons to centralise.
7.1.6
Line and staff
Line managersManagers with authority over specified people and activities in the direct chain of command.
Staff managersSpecialist managers responsible for support functions such as human resources or information technology.
Line managers
They normally manage departments, people and operational resources. Their work directly contributes to producing or selling the organisation's goods and services and to achieving corporate objectives.
Examples: sales manager, production manager, branch manager.
Staff managers
They provide specialist support that enables line functions to operate effectively. Their contribution to revenue is normally indirect, but their expertise can be essential.
Examples: HR manager, IT manager, legal adviser.
Why conflict can occur
- Different priorities: line managers may focus on sales, output or revenue while staff managers may require spending on systems, recruitment, training or compliance.
- Status concerns: line managers may feel specialist staff managers are interfering with their authority.
- Different knowledge: staff specialists may recommend policies that line managers think do not fit local operational realities.
- Ignored expertise: staff managers may feel their specialist advice is not taken seriously when final decisions are made by line managers.
- Overlapping authority: conflict is more likely if the business has not clearly defined which manager controls which decision.
Is there a best organisational structure?
No single structure is best for every organisation or even for every part of the same organisation. A large business may use different arrangements in different areas. Research and development might operate informally to encourage creative specialists; administration might use a more traditional hierarchy for consistency; marketing projects might use matrix teams to combine skills.
The danger of using several structures is that coordination can become difficult and divisions may pursue their own objectives. Senior managers therefore need clear corporate goals, communication and accountability systems to keep the organisation aligned.
Final evaluation rule: judge a structure by whether it helps the business achieve its objectives. Consider size, product complexity, workforce skills, geographical spread, need for innovation, cost pressures, speed of response, risk and leadership style.
