IB Business Management HL Unit 1.1 — What Is a Business? Paper 1 & 2 Core idea ~10 min read

What a Business Actually Does

Take away the logo, the offices and the adverts, and every business on earth is doing the same simple thing. It takes things in, changes them, and sells the result for more than the things cost. Once that clicks, most of Unit 1 stops feeling like a list to memorise.

📘 What you need to know

Every business is a transformation process

A bakery buys flour, yeast and electricity. It uses bakers, ovens and a shop. Out the other end come loaves that people pay for. A bank buys computers and hires advisers, and out comes a mortgage. Different industries, identical shape.

The transformation process Things go in, the business changes them, something more valuable comes out INPUTS people materials money machines THE BUSINESS changes the inputs into something worth more OUTPUTS goods services sold to customers added value = selling price − cost of bought-in materials A bakery, a bank and a barber all follow this same shape. The wider the gap between what inputs cost and what outputs sell for, the more value has been added.
The middle box is where the business earns its keep. If a firm cannot make the output worth more than the inputs, there is no reason for it to exist.

Goods and services

The syllabus splits outputs into two types, and the difference matters more than it looks.

FeatureGoodsServices
Physical?Yes — you can touch itNo — nothing to hold
Can be stored?Yes, in a warehouseNo — an empty seat is lost forever
Made before it is sold?Usually yesUsually produced as it is consumed
ExamplesTrainers, cars, phones, breadHaircuts, insurance, streaming, flights
The “cannot be stored” point is worth remembering. It is why airlines drop prices at the last minute and why a hotel would rather sell a room cheaply than leave it empty. Once the night has gone, that sale can never be made again.

The four resource inputs

When a case study says a firm is “struggling to expand”, the reason is nearly always that one of these four is missing.

InputWhat it meansWhat it looks like in a case study
HumanThe people who do and manage the workTrained staff, enough of them, with the right skills
PhysicalThe things you use to make the productPremises, machinery, vehicles, raw materials
FinancialThe money that pays for everything elseOwner’s capital, bank loans, cash to pay bills
EnterpriseThe idea, and the nerve to risk money on itThe founder who spots the gap and acts on it

Added value: where the money really comes from

Added value is the difference between what you paid for the bought-in materials and what you sell the finished thing for. It is the reward for doing the transforming.

Added value added value = selling price − cost of bought-in materials
Where added value comes from A sandwich shop: what the bread and filling cost, next to what the sandwich sells for £1.20 cost of ingredients £3.50 added value £2.30 ingredient cost selling price Added value is not profit. Wages, rent and bills still come out of it. Profit is what survives after every cost, not just the cost of the materials.
The green block is added value. Branding, speed, a nice shop and a friendly server all sit inside it — and so do all the wages that still have to be paid.
WORKED EXAMPLE

Calculating added value

A furniture maker buys wood, screws and varnish costing £145 for one table. Wages for the carpenter come to £90 and the workshop costs £40 per table. The table sells for £420. Calculate the added value per table, and the profit per table.

Step 1: added value uses bought-in materials only added value = 420 − 145 = 275 Added value = £275 per table Step 2: profit takes off every cost total costs = 145 + 90 + 40 = 275 profit = 420 − 275 = 145 Profit = £145 per table two very different numbers — read the question wording carefully

Capital intensive or labour intensive?

Every transformation process leans one way or the other. Ask which cost is the biggest.

Why the examiner cares: the choice explains a firm’s behaviour. Capital intensive firms chase high output to spread their fixed costs. Labour intensive firms chase cheap labour, which is why so much clothing is made in South-East Asia.

The four business functions

In a one-person business the owner does all four jobs on the same afternoon. In a large firm each becomes a whole department with its own targets.

The four functions pull on each other HUMAN RESOURCES hiring, training, pay, health and safety MARKETING research, price, promotion, place FINANCE budgets, accounts, raising the money OPERATIONS making it, stock, quality, delivery all aimed at the same objectives A change in one function creates work in the other three. Marketing spots a new need, finance funds it, HR trains for it, operations builds it.
This is what “interdependent” means. It is also the easiest way to earn evaluation marks: show how one department’s decision lands on another department’s desk.

🧩 How to answer “explain the interdependence of functions”

  1. Pick one trigger from the case study — new product, falling sales, a big order.
  2. Follow it round the loop. Name each function in turn and say exactly what it has to do.
  3. Say what breaks if one function fails to keep up. That is the analysis mark.
  4. Use the firm’s own words. Generic answers about “communication” score badly.
EXAM-STYLE

Explain how the four business functions are interdependent. [4]

A small brewery decides to launch a low-alcohol beer after research shows demand rising.

Marketing starts it Research finds the demand and sets the price and packaging. Finance makes it possible It has to budget for new tanks and check the firm can afford them. HR staffs it Brewers need training on the new process, and an extra shift may be needed. Operations delivers it It changes the production line and keeps quality steady at higher volume. Each one depends on the others doing their part if finance refuses the budget, marketing’s plan dies on the page
