SWOT analysis is a simple framework for generating strategic alternatives from a situation analysis. It is applicable to either the corporate level or the business unit level and frequently appears in marketing plans. SWOT (sometimes referred to as TOWS) stands for Strengths, Weaknesses, Opportunities, and Threats. The SWOT framework was described in the late 1960's by Edmund P. Learned, C. Roland Christiansen, Kenneth Andrews, and William D. Guth in Business Policy, Text and Cases (Homewood, IL: Irwin, 1969). The General Electric Growth Council used this form of analysis in the 1980's. Because it concentrates on the issues that potentially have the most impact, the SWOT analysis is useful when a very limited amount of time is available to address a complex strategic situation.
