A business is any organisation that uses resources to produce goods or services which satisfy the needs and wants of customers, usually to earn a profit.
Needs and wants
Economists separate the things people buy into two groups: needs — essentials we cannot manage without, such as food, clean water and shelter — and wants — extras that make life more comfortable, such as a smartphone or a holiday. Because wants are unlimited but resources are scarce, people must choose what to buy, and businesses succeed when they meet a real need or a strong want.
What a business does
A business takes inputs — the factors of production — and turns them into outputs: goods (physical items like dates or a repaired phone) or services (actions like a haircut or delivery).
For example, Aisha's phone-repair shop uses a rented unit (land), her own skill and staff (labour), tools and money (capital), and her own decision-making (enterprise) to fix phones.
Adding value
The most important idea is adding value: making the output worth more to the customer than the cost of the inputs.
Added value = selling price − cost of bought-in materials
If Yusuf buys plain fabric for £5 and turns it into a modest scarf he sells for £18, he has added £13 of value through his design and stitching. Selling honestly and giving fair value for money is not only good ethics; it also builds the trust that keeps customers coming back.
