Organisation Structure & Employees
The big idea: every business has to decide who's in charge of who, how decisions get made, and who does what job — and that one decision shapes how fast, how happy, and how well the whole business runs.
- An organisational structure maps out who reports to who, and who's responsible for what.
- Structures are usually shown on an organisation chart, and described using hierarchy, chain of command, and span of control.
- A long chain of command + narrow span of control = hierarchical (tall) structure. A short chain + wide span = flat structure.
- Businesses can also be centralised (decisions made at the top) or decentralised (decisions pushed down the hierarchy).
- Delegation is a manager handing a task — and the authority to do it — to someone below them. It's central to how flat structures actually work.
- Employees fall into roles: directors (strategy), managers (senior, functional, supervisors), and operational/support staff (day-to-day work).
- Businesses are organised into functional areas / departments: Human Resources, Finance, Marketing, and Production — each with its own job, but all needing to work together.
What is an organisational structure?
Think of a business like a football team. Everyone can't just run around doing whatever they want — someone has to be the manager, someone the captain, and everyone else needs to know their position and who to listen to. That's exactly what an organisational structure does for a company: it lays out the reporting relationships, roles, and responsibilities of every employee, so that when a decision needs making, everyone knows whose job it is to make it.
Businesses pick a structure carefully because it affects how well the business communicates, how fast it makes decisions, and ultimately whether it can actually achieve its objectives. A badly designed structure is like a football team where three players all think they're the goalkeeper — chaos.
This is usually drawn out visually as an organisation chart — a diagram (like a family tree) showing every position and who reports to who.
This is a traditional hierarchy — workers answer to a supervisor, who answers to a manager, who answers up the chain all the way to the top.
1. Hierarchy
A hierarchy is simply the levels of authority in an organisation — the ranking of positions from top to bottom. The higher up the hierarchy someone sits, the more authority and power they have. Most hierarchies have three broad bands: top-level management (directors, CEO), middle-level management (functional managers), and lower-level employees (operational staff).
2. Chain of Command
The chain of command is the formal line of authority that runs downward from top management to the lowest-level employees. It answers two questions: who reports to whom? and who's actually responsible for making a decision? A clear chain of command keeps communication flowing properly and keeps everyone accountable — if something goes wrong, you can trace exactly who was responsible.
Long chain of command = lots of steps between the top and the bottom (like a huge company with 6 layers of management between a factory worker and the CEO). Short chain of command = few steps (like a 10-person start-up where everyone reports almost directly to the founder).
3. Span of Control
The span of control is the number of people a manager or supervisor directly manages. This is based on a very human idea: a manager can only properly look after so many people before quality drops. Think of a teacher — one teacher can effectively manage a class of 25, but couldn't effectively manage 300 students all learning different things at once.
Wider span of control → fewer layers of management needed.
Flat vs Hierarchical Structures
Chain of command and span of control are joined at the hip — you basically can't change one without changing the other.
- Long chain of command + narrow span of control = a hierarchical (tall) structure. Picture a tall, narrow pyramid.
- Short chain of command + wide span of control = a flat structure. Picture a short, wide pyramid.
| Hierarchical Structure | Flat Structure |
|---|---|
| Multiple levels of management | Few levels of management |
| Long chain of command, narrow span of control | Short chain of command, wide span of control |
| Common in large organisations with complex operations (e.g. government agencies, universities) | Common in small organisations or start-ups (e.g. tech start-ups, small businesses) |
| Hierarchical — Advantages | Hierarchical — Disadvantages |
|---|---|
| Clear structure of authority and defined roles; promotes specialisation and expertise within each department | Communication barriers between upper and lower levels; decision-making can be slow as info passes through many layers |
| Flat — Advantages | Flat — Disadvantages |
|---|---|
| Promotes collaboration and open communication; decision-making can be faster and more efficient | Roles and management may not be clearly defined; employees may take on multiple roles, leading to burnout and stress |
Centralised vs Decentralised Structures
This is a different way of slicing the same question: who actually gets to make decisions?
- Centralised structure: authority for decision-making sits with senior management at the centre (head office) of the business.
- Decentralised structure: authority is delegated further down the hierarchy to functional or middle managers, closer to where the action happens.
In real life, almost no business is 100% one or the other. Most use a mix: strategic decisions (like "should we expand into a new country?") stay with senior leaders, while operational decisions (like "what time should this store open on Sundays?") get delegated to functional areas and middle managers who know the local situation better.
| Advantages | Disadvantages | |
|---|---|---|
| Centralised | Effective co-ordination and control from the centre; fast, decisive decision-making can boost competitiveness; consistency across the whole organisation | Middle managers' lack of autonomy can hurt motivation; highly bureaucratic, slowing communication; ignores insights of lower-level staff who are closer to customers |
| Decentralised | Better able to respond to local market conditions and customer needs; staff who contribute to decisions may be more fulfilled and loyal; prepares junior managers for career development | Diseconomies of scale (e.g. duplicated staff roles); harder to tightly control budgets; unclear leadership during a crisis |
The shorter the chain of command → the wider the span of control.
Business Roles at a Glance
Larger firms are usually arranged into functional departments (like finance and marketing), each led by a director who carries final responsibility for everyone's work in that department.
The Role of Directors
Larger businesses often have a board of directors — the people who make the big, strategic decisions that shape the whole company's future, such as:
- Implementing new corporate policies
- Deciding how to invest retained profit and share capital
- Setting growth objectives
The board typically includes a senior employee from each department, officers (like a treasurer or secretary), and the owner or CEO.
The Role of Managers
Managers keep the business running smoothly day-to-day. There are three main types, and it's easy to mix them up — so here's a clean breakdown:
| Role | Responsibilities |
|---|---|
| Senior manager | Plans to achieve the business' overall goals; sets long-term plans and targets; contributes to strategic decisions |
| Functional manager | Works to achieve short/long-term targets set by directors and senior managers; responsible for running a function (e.g. marketing or finance); makes operational decisions; uses employees and resources effectively |
| Supervisor / team leader | Helps managers hit targets by reporting problems and passing on instructions; takes simple decisions like allocating jobs among employees |
Below managers sit operational staff (who carry out the tasks they're directed to do — e.g. sales assistants, security staff in a department store) and support staff (who assist with the non-core operations — e.g. cleaners, IT technicians, HR assistants in a bank).
Delegation
Delegation is the process of a manager handing responsibility for a specific task — and the authority to carry it out — to a subordinate. It's not just "giving someone a job to do"; it specifically involves passing down some of the manager's own authority.
Delegation matters most in businesses with a flat structure, because managers there have a wide span of control — they simply cannot do everything themselves, so they must trust others with real authority.
| Advantages for Managers | Advantages for Workers |
|---|---|
| Lets managers focus on important tasks instead of doing everything themselves | Workers feel empowered in decision-making, which can motivate them |
| Helps managers measure staff performance by seeing how well they carry out delegated tasks | Acts as a form of training — workers learn on the job, boosting future promotion chances |
| Can reduce errors, since workers may be more skilled/have more time for the specific task | Makes work more interesting and rewarding, which can reduce absenteeism and staff turnover |
Despite these benefits, some managers are reluctant to delegate because they lose some control over decision-making. This especially applies to autocratic leaders (who like to keep control themselves), or managers who feel threatened by highly skilled subordinates chasing their job.
What is a Functional Area?
A functional area is a group of workers with similar skills and expertise, carrying out a specific organisational role — basically, a department. Businesses split work up this way because it lets specialists focus on what they're best at, improving overall efficiency. Sometimes these functions are outsourced to specialist providers outside the business, which can reduce costs and give access to expert advice the business couldn't otherwise afford to employ directly.
Human Resources (HR)
HR manages the workforce and looks after employee welfare, including:
- Recruitment and selection
- Training and development
- Maintaining healthy industrial relations
- Ensuring compliance with health and safety regulations
Finance
Finance manages the organisation's money, including:
- Recording all incoming and outgoing financial transactions
- Collecting debts owed to the business
- Ensuring bills and salaries are paid on time
- Setting and maintaining budgets
- Conducting financial forecasting
- Managing banking operations
- Preparing the annual financial report
Marketing
Marketing focuses on understanding the needs and wants of both existing and potential customers, including:
- Researching the market to plan products that meet consumer demand
- Organising distribution
- Persuading customers to purchase goods or services
- Determining pricing tactics that attract and retain customers
Production
Production is centred on actually creating the product or delivering the service, including:
- Ensuring the quality of output
- Sourcing and purchasing raw materials and components
- Managing the design and testing of new products
- Inventory management
The key idea to remember: functional areas can't work in silos — they need each other to hit business objectives.
| Finance | Human Resources | Marketing | Production |
|---|---|---|---|
| Sets budgets so marketing knows how much they have to spend on promotional activity | Recruits staff for the finance function and organises induction training so new staff settle in quickly | Carries out research to find customer needs, which informs the production function about what to make | Reports output and wastage data to finance, which calculates manufacturing costs and profit margins |
Know your definitions cold
This topic is heavily tested in multiple choice and "state"/"define" questions — meaning there's often no room for a fuzzy half-answer. Practise writing out precise definitions for hierarchy, chain of command, span of control, delegation, centralised, and decentralised.
Don't confuse hierarchy with chain of command
Hierarchy = the levels/ranking of authority. Chain of command = the actual line/path of authority flowing down. They're related but not the same thing — examiners often test whether you can tell them apart.
Always link chain of command and span of control
If asked to describe a structure, always mention both together: a long chain of command goes hand-in-hand with a narrow span of control (and vice versa). Stating only one shows incomplete understanding.
Delegation isn't automatically a good thing
When analysing or evaluating delegation as a motivator, always weigh it both ways — some workers thrive with more responsibility, but others may feel anxious or lack the necessary skills. A one-sided answer loses marks on evaluation-style questions.
HR is commonly under-understood
Examiners have specifically noted weak candidate understanding of the Human Resources function. Make sure you can name all four of its core responsibilities (recruitment, training, industrial relations, health & safety compliance) without hesitation.
Use real examples in evaluation questions
Questions on centralised vs decentralised, or flat vs hierarchical, often ask you to apply your answer to a specific business context (e.g. a multinational vs a small start-up). Always tie your advantages/disadvantages back to the scenario given in the question.
