These educational posters can be used in conjunction with Ralph Pirozzo’s book The Thinking School (HB7658). The SOWC Analysis poster is the author’s interpretation of the well – known SWOT Analysis (Strengths, Weaknesses, Opportunities and Threats). The SWOT Analysis is credited to Albert Humphrey, who used this technique in the 1960s and 1970s. The aim of SWOT is to identify the key internal factors (strengths and weaknesses) and external factors (opportunities and threats) that are important in achieving an objective.
