Ansoff's Matrix provides a framework for identifying corporate growth opportunities based on two dimensions: products and markets. It outlines four generic growth strategies - market penetration, market development, product development, and diversification - with increasing levels of risk. Market penetration involves selling more of the existing product to the current customer base. Market development uses the existing product but targets new customer segments. Product development creates new products for current customers. Diversification carries the highest risk as it pursues new products and new customers simultaneously. The matrix helps analyze growth options and their associated risks.
