PEST Analysis is used to assess the market environment for a business.
There are variations of the model which identify other factors, although some researchers argue that those additional factors are just aspects of the main four. Variations include reorganization of the letters (ESTP, STEP) or the addition of Legal, Environmental, Ethical, Legislative, International, Industry, or Demography (PESTLE, STEEP, STEPE, STEEPLED, PESTELI).

Other authors have reorganized the letters and added new categories over the years. The following articles include some of the variants.
