What this dot point is asking
AQA wants you to analyse the external environment using PESTLE, explain how market conditions, competition, the economic climate and legislation affect a business, and explain why firms must monitor and respond to a changing environment. The economic factors, especially interest rates, exchange rates and the cycle, are heavily examined.
The external environment and PESTLE
PESTLE is a checklist that stops a firm overlooking an important influence; it feeds the opportunities and threats in a SWOT and the external analysis of strategic position.
The economic climate
For example, a fall in the pound makes UK exports cheaper abroad (good for exporters) but raises the cost of imported materials (bad for firms reliant on them), so the same change helps some firms and hurts others.
Competition and legislation
Competition shapes how much freedom a firm has on price and how hard it must work on quality, innovation and marketing. In a highly competitive market, firms are price-takers with thin margins; with little competition, they have more pricing power. Legislation sets the rules: employment law (minimum wage, working time), consumer protection, competition law, and health and safety. Compliance raises costs but protects the firm from fines and reputational damage, and firms that adapt early can turn new rules into an advantage.
Why firms must monitor and respond
The external environment is dynamic: economies move through cycles, technology disrupts, tastes shift and laws change. A firm that monitors these (through PESTLE scanning and market research) can adapt early, seizing opportunities and defusing threats, while one that ignores them risks being overtaken, like high-street retailers slow to move online. Monitoring and responsiveness are therefore central to long-run survival and success.

AQA 20219 marksAnalyse how a rise in interest rates might affect a house-building business. (9 marks)Show worked answer →
Trace the economic mechanism through to the firm.
Higher interest rates raise the cost of mortgages, so fewer people can afford to buy homes and demand for new houses falls, cutting the builder's sales and revenue. Higher rates also raise the cost of the builder's own borrowing, increasing interest on loans used to fund land and construction, which squeezes profit and may force it to delay projects. Consumer confidence often falls too, further weakening demand for big-ticket purchases like houses.
A balanced answer notes the builder could respond (smaller or cheaper homes, slowing land purchases) and that effects depend on the size of the rise and how long it lasts. Markers reward a clear chain from higher rates to lower demand and higher financing costs, applied to a house builder, with the depth and a response or caveat lifting it into the top band.
AQA 20186 marksExplain how two PESTLE factors could create opportunities or threats for a supermarket. (6 marks)Show worked answer →
Choose two factors and develop each as an opportunity or threat.
Technological: the growth of online shopping and apps is an opportunity for a supermarket to expand home delivery and personalise offers, but also a threat from online-only rivals. Legal or environmental: new regulations on plastic packaging or food labelling are a threat that raises compliance costs, but adapting first can become an opportunity to attract eco-conscious customers. Each factor should be linked clearly to a specific opportunity or threat for the supermarket. Markers reward two correctly identified PESTLE factors, each explained as a concrete opportunity or threat in context, not just defined.
