SOSTAC(r) is a marketing model developed by PR Smith in the 1990s and later formalized in his 2004 book, Strategic Marketing Communications. It is an acronym for Smith's six fundamental facets of marketing: situation, objectives, strategy, tactics, action and control.
SOSTAC(r) contains a general marketing strategy which can be applied in various commercial situations. It is an extension of the SWOT analysis, which helps businesses get ready for marketing campaigns; the main difference is that SOSTAC focuses more on the implementation stages of the process and on marketing communications.
Marketing experts have adapted SOSTAC to a number of specific situations, including direct marketing and electronic marketing. The steps in the process have also been adapted to the development of internet security systems and company business plans.
