SWOT-Analysis is a strategic planning technique developed by the Harvard Business School in the 1960s. It is used to analyse the competitiveness of businesses and organisations.
Nowadays, SWOT-Analysis is not only used to evaluate businesses, but also the competitiveness for example of cities, regions and nations and public sector organizations.
PESTLE-Analysis is a framework for environmental scanning used in strategic management or market research. It can be used to understand potential for market growth but also decline and therefor be used to decide about business direction in the future.
It includes six factors: Political, Econonomic, Social, Technological, Legal and Environmental factors. A shorter version of the PESTLE-Analysis is the PEST-Analysis, which only takes the first four factors into account.
