Strategic group analysis (SGA) is a tool used to analyze an organization's competitive environment. SGA identifies groups of competitors that follow similar strategies or compete on similar bases. Groups are identified using characteristics like product diversity, market segments served, and branding. SGA helps identify direct competitors and the basis of competition. It can also reveal opportunities and strategic problems. The process involves analyzing industry structure, mapping strategic groups, assessing competitiveness, and understanding strategic interactions. Conducting SGA involves using criteria like integration, market segmentation, ownership structure, and cost structure to distinguish groups.
