The document discusses the Boston Consulting Group (BCG) Matrix, which classifies businesses into four categories based on their relative market share and market growth rate. The four categories are stars, question marks, cash cows, and dogs. Stars have high market share and growth, while cash cows have high share but low growth. Question marks and dogs have low relative market share, with question marks in a high growth market and dogs in a low growth market. The BCG Matrix helps assess businesses and allocate resources to maximize growth and profits. While simple, it has limitations as it only considers two factors and data may not always be available.
