business analysis, PEST analysis ("political, economic, socio-cultural and technological") describes a framework of macro-environmental factors used in the
environmental scanning component of
strategic management. It is part of an external environment analysis when conducting a strategic analysis or doing
market research, and gives an overview of the different macro-environmental factors to be taken into consideration. It is a strategic tool for understanding market growth or decline, business position, potential and direction for operations.
PEST analysis was developed in 1967 by
Aguilar as an
environmental scanning framework. Aguilar argued that firms must scan the economic, technical, political and social categories (ETPS) that may affect strategy, defining environmental scanning as follows, “scanning for information about events and relationships in a company’s outside environment, the knowledge of which would assist top management in its task of charting the company’s future course of action.”
Social factors include the cultural aspects and health consciousness, population growth rate, age distribution, career attitudes and emphasis on safety. High trends in social factors affect the demand for a company's products and how that company operates. For example, the ageing population may imply a smaller and less-willing workforce (thus increasing the cost of labour). Furthermore, companies may change various management strategies to adapt to social trends caused from this (such as recruiting older workers).
Variants that build on the PEST framework include:
PESTEL or PESTLE, which adds
environmental factors. Legal factors include
employment law, and
health and safety law, which can affect how a company operates, its costs, and the demand for its products.
Environmental factors include ecological and environmental aspects such as weather, climate, and
climate change, which may especially affect industries such as tourism, farming, and insurance. For instance, growing awareness of the potential impacts of climate change is affecting how companies operate and the products they offer, both creating new markets and diminishing or destroying existing ones. Further, the PESTLE analysis is one of the most frequently applied models in the evaluation of the highly dynamic external business environment. It is employed as a method in research due to its usefulness. For example. a growing number of studies applied this analytical tool in different sustainable projects, including the evaluation of external factors affecting management decisions for coastal zone and freshwater resources, development of sustainable buildings,sustainable energy solutions, and transportation.
ETPS economic, technical, political and social.
STEEPLE and STEEPLED, adding ethics and
demographic factors (occasionally rendered as PESTLEE). Demographic 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.
DESTEP, adding demographic and ecological factors.
SPELIT, adding legal and
intercultural factors. Intercultural factors considers collaboration in a global setting. Other factors discussed in chapter 10 of the SPELIT Power Matrix include the Ethical, Educational, Physical, Religious, and Security environments.
PMESII-PT, a form of environmental analysis which looks at the aspects of political, military, economic, social, information, infrastructure, physical environment and time aspects in a military context.
STEER considers sociocultural, technological, economic, ecological, and
regulatory factors, but does not specifically include political factors.
TELOS framework explores Technical, Economic, Legal, Operational, and Scheduling factors.
Applicability of the factors
The model's factors will vary in importance to a given company based on its industry and the goods it produces. For example, consumer and
B2B companies tend to be more affected by the social factors, while a global defense contractor would tend to be more affected by political factors. Additionally, factors that are more likely to change in the future or more relevant to a given company will carry greater importance. For example, a company which has borrowed heavily will need to focus more on the economic factors (especially interest rates). Furthermore, conglomerate companies who produce a wide range of products (such as Sony, Disney, or BP) may find it more useful to analyze one department of its company at a time with the PESTEL model, thus focusing on the specific factors relevant to that one department. A company may also wish to divide factors into geographical relevance, such as local, national, and global.
Whereas the PEST analysis is broadly used in business practice, critics argue that it has 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 reason is that PEST analysis offers a broad range of categories that can be deceivingly simple because they lack specific criteria about what exactly catalyses disruption. In other words, the PEST analysis does not offer guidelines for what to emphasise and what not to emphasise within the categories. As a result, firms can be blindsided by disruptions that cannot be neatly defined within the categories.
