A PEST analysis (also sometimes called a STEP, PESTLE or STEEP analysis) looks at the external business environment. PEST stands for Political, Economic, Sociocultural and Technological. Technological factors in this case, include ecological / environmental aspects - the second E in STEEP and PESTLE, while legislative factors are included under Political (the L in PESTLE). The analysis examines the impact of each of these factors (and their interplay with each other) on the business. The results can then be used to take advantage of opportunities and to make contingency plans for threats.
Political Factors.
When examining political factors, you need to look at any political changes that could effect your business. What laws are being drafted? What global changes are occurring? Legislation on maternity rights, data protection, health & safety, environmental policy, should be considered, for example.
As an example, take a company employing a large number of women. Changes in maternity rights may have a major impact on such a business - and the aware business will keep an eye out for changes in such legislation.
Economic Factors.
Often the political factors spill over into economic factors. For example, tax is usually decided by politicians, based on a mixture of political and economic factors. Interest rates, in many countries are decided by a central bank, but political factors may still be important. The fall of the Soviet Union caught most businesses and Western Governments by surprise - but not all. Some companies - notably Shell Petroleum - had picked up signals that all was not well in Russia. Many of these were related to economic problems within the Soviet Union.
Other economic factors include exchange rates, inflation levels, income growth, debt & saving levels (which impact available money) and consumer & business confidence. The current state of world stock markets is a typical example of the volatility of economic factors.
