Ansoff's Matrix helps businesses organize growth ideas into existing or new products in existing or new markets, with four quadrants that represent different growth strategies with varying levels of risk. The lowest risk is market penetration by selling more to existing customers. Higher risk strategies include market development by entering new geographic or industry markets, product development by creating new products for existing customers, and diversification by developing new products for new markets. The document provides examples for each quadrant to illustrate different growth opportunities and recommends understanding the risks before pursuing strategies that move the business away from its core.
