PEST analysis

PEST analysis is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand PEST analysis rather than just read about it. In short: In business analysis, PEST analysis (political, economic, social and technological) is a framework of external macro-environmental factors used in strategic management and market research. PEST analysis was developed in 1967 by Francis Aguilar as an environmental scanning framework for businesses to understand the external conditions and relations of a business in order to assist managers in strategic planning.

Key takeaways

  • PEST analysis belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect PEST analysis to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of PEST analysis from memory before moving on to harder problems.

Reference excerpt

In business analysis, PEST analysis (political, economic, social and technological) is a framework of external macro-environmental factors used in strategic management and market research. PEST analysis was developed in 1967 by Francis Aguilar as an environmental scanning framework for businesses to understand the external conditions and relations of a business in order to assist managers in strategic planning. It has also been termed ETPS analysis. PEST analyses give an overview of the different macro-environmental factors to be considered by a business, indicating market growth or decline, business position, as well as the potential of and direction for operations.

Components The basic PEST analysis includes four factors: political, economic, social, and technological.

Political Political factors relate to how the governments intervene in economies. Specifically, political factors comprise areas including tax policy, labour law, environmental law, trade restrictions, tariffs, and political stability. Other factors include what are considered merit goods and demerit goods by a government, and the impact of governments on health, education, and infrastructure of a nation.

Economic Economic factors include economic growth, exchange rates, inflation rate, and interest rates.

Social Social factors may extend to cultural factors, including health consciousness, population growth rate, age distribution, career attitudes and safety emphasis. Trends in social conditions affect the demand for a company's products and how they are obtained, e.g. a shift away from city centre shopping to out-of-town locations might affect how a company operates. Similarly social factors affect supply, employment factors and workforce matters. Through analysis of social factors, companies may adopt various management strategies to adapt to social trends.

Technological Technological factors include R&D activity, automation, technology incentives and the rate of technological change. These can determine barriers to entry, minimum efficient production level and influence the outsourcing decisions. Technological shifts would also affect costs, quality, and innovation.

Variants Many similar frameworks have been constructed, with the addition of other components such as environment and law. These include PESTLE, PMESII-PT, STEPE, STEEP, STEEPLE, STEER, and TELOS.

Legal and regulatory Legal factors include discrimination law, consumer law, antitrust law, employment law, and health and safety law, and the law of carriage and transport, which can affect how a company operates, its costs, and the demand for its products. Regulatory factors have also been analysed as a separate pillar.

Environment Environmental factors include ecological and environmental aspects such as weather and climate, which may especially affect industries such as tourism, farming, and insurance. Environmental analyses often use the PESTLE framework, which allow for the evaluation of factors affecting management decisions for coastal zone and freshwater resources, development of sustainable buildings, sustainable energy solutions, and transportation.

Demographic Demographic factors have been considered in frameworks such as STEEPLED. Factors include gender, age, ethnicity, knowledge of languages, disabilities, mobility, home ownership, employment status, religious belief or practice, culture and tradition, living standards and income level.

Military Military analyses have used the PMESII-PT framework, which considers political, military, economic, social, information, infrastructure, physical environment and time aspects in a military context.

Operational The TELOS framework explores technical, economic, legal, operational, and scheduling factors in the context of project management and feasibility studies.

Limitations PEST analysis can be helpful to explain market changes in the past, but it is not always suitable to predict or foresee upcoming market changes. The macro-environment is highly fluid, and factors can shift unpredictably. Tovstiga and Aylward warn against the danger of listing factors without understanding their "cause-and-effect relationship" with business activities and market outcomes: "it is all too easy to produce lists of factors ... developing a clear understanding" about these relationships is "more challenging".

Worked examples

Example 1 — a first encounter with PEST analysis

Start with the simplest possible case. Write down what PEST analysis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PEST analysis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PEST analysis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PEST analysis

In research
PEST analysis appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses PEST analysis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
PEST analysis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Analysis, Management theory, Strategic management, so understanding it makes those chapters shorter.
In everyday life
Look for PEST analysis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does PEST analysis matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study PEST analysis?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
