The document discusses patterns of target market selection. It identifies five patterns: single segment concentration, selective segment specialization, market specialization, product specialization, and full coverage. For each pattern it provides examples of companies that use each approach and describes the basic strategy. The key factors to consider when selecting target markets are the segment's size, growth, profitability, and compatibility with company objectives and resources. The ultimate goal is to identify those market segments that will form the target market for a company's products or services.
