Answer to Question 2

SWOT stands for strengths, weaknesses, opportunities, and threats. In the S and W, we're characterizing the company: What are our strengths and weaknesses? In the O and T, we're characterizing the broader environment (e.g., industry, suppliers, government, etc.): What are the opportunities and threats? S and W are considerations internal to the organization; and O and T are external.
SWOTs are useful in clarifying most marketing questions. In such an analysis, we can declare our strengths and weaknesses relative to our competitors, but our opinion doesn't matter as much as that of the customer base. Hence, we'd obtain some marketing research data, such as the perceptual maps described in the chapter. If our brands, product lines, and company have perceived weaknesses in areas that customers care about, clearly we should address those shortcomings. If our brands and products have perceived strengths, we will consider what we can do to ensure that these will be sustainable competitive advantages.
