GCSE / Level 2 Revision Notes

External Environment: Economic sectors

Business activity is the process of transforming inputs into outputs by adding value. There are three main sectors of business activity:

Primary sector Involves the extraction and production of raw materials, such as coal, wood and steel. A coal miner and a fisherman would be workers in the primary sector.

Secondary sector Involves the transformation of raw materials into goods e.g. manufacturing steel into cars. A builder and a dressmaker would be workers in the secondary sector.

Tertiary sector Involves the provision of services to consumers and businesses, such as cinema and banking. A shopkeeper and an accountant would be workers in the tertiary sector.

Goods move through a “chain of production”. The chain of production follows the construction of a good from its extraction as a raw material through to its final sale to the consumer. So a piece of wood is cut from a felled tree (primary sector), made into a table by a carpenter (secondary) and finally sold in a shop (tertiary).

Some businesses have elements of all sectors in their chain of production. Others businesses choose to specialise. Specialisation occurs when a producer concentrates on making a small number of products, or on providing a narrowly defined service.

Examples of specialisation:

• Baker only baking bread
• Machinery that only cuts sheet metal
• Lawyer dealing only with criminal law

Advantages of specialisation

Producer becomes more efficient because they learn the best way (all the short cuts) to produce at the lowest cost

A producer may be able to charge a higher price from a customer – the customer is prepared to pay more for expert/specialist knowledge (e.g. a cosmetic surgeon)
