A business is rarely run by one person doing everything. As it grows, work is split into departments, each responsible for a particular function. This lets staff specialise, avoids duplicated effort and makes it clear who is accountable for what. For IGCSE Business Studies you need to know the main departments, what each one does, and how they depend on each other.
The main departments at a glance
| Department | Main purpose | Typical tasks |
|---|---|---|
| Marketing | Find out what customers want and persuade them to buy | Market research, pricing, promotion, choosing where to sell |
| Finance | Manage the money coming into and going out of the business | Keeping accounts, paying wages and suppliers, preparing budgets and financial statements |
| Human resources (HR) | Recruit, train and look after the workforce | Recruitment and selection, training, pay and contracts, handling disputes |
| Operations (production) | Make the product or deliver the service | Managing production, quality control, stock, purchasing |
| Administration | Keep the business running smoothly day to day | Reception, filing, record keeping, IT support, communication |
Marketing department
The marketing department identifies customer needs and makes sure the business offers the right product, at the right price, in the right place, with the right promotion. It carries out market research, plans advertising and sales promotions, and decides which products to launch or improve.
Finance department
The finance department controls the business's money. It records every transaction, pays employees and suppliers, collects payments from customers, and sets budgets for the other departments. It also prepares financial statements, such as the income statement and statement of financial position, which show managers, owners, lenders and tax authorities how the business is performing. Without good financial control a profitable business can still run out of cash and fail.
Human resources (HR) department
The human resources department looks after the people who work for the business. Its main jobs are to plan how many staff are needed, recruit and select new employees, arrange induction and training, manage pay and working conditions, and deal with grievances and dismissals. It must also make sure the business follows employment laws, for example on health and safety and discrimination.
Operations (production) department
The operations department turns inputs such as materials, labour and machinery into the goods or services the customer buys. It decides the production method, buys raw materials, controls stock levels and checks quality. A manufacturer's operations department runs the factory; a restaurant's operations team prepares and serves the food. If it is inefficient, costs rise and customers receive late or poor-quality products.
Administration department
Administration supports every other department. It handles incoming calls and visitors, post and email, filing and record keeping, and often IT systems and office equipment. Good administration keeps information flowing and saves other departments' time, but it rarely earns revenue directly, so businesses try to keep its costs under control.
How departments work together
Departments are not independent. A decision in one affects the others, so businesses rely on communication and co-ordination.
- Marketing finds demand for a new product, then operations plans how to make it.
- Operations needs staff to run production, so HR recruits and trains them.
- HR needs a wage budget, so finance approves the money.
- Finance relies on sales figures from marketing and cost figures from operations to prepare budgets.
- Administration records orders and passes messages between all of them.
When departments do not communicate well, problems appear: marketing may promise a delivery date that operations cannot meet, or HR may hire more staff than finance can afford. Many businesses reduce this risk with regular meetings, shared systems and cross-department project teams.

Explain one way in which the human resources department helps a business to grow. [3 marks]

A furniture maker's marketing department has found that customers want cheaper flat-pack tables. Explain how the operations and finance departments will each need to respond. [6 marks]
Show model answer
Operations: it must redesign the product and change the production method and materials (1) to make flat-pack tables at a lower unit cost while keeping quality (1), and may need to order new components and adjust stock levels (1). Finance: it must set a budget for the new product (1), approve spending on new machinery or materials (1) and check that the lower price still leaves enough profit, by comparing expected sales revenue with costs (1).
