The document provides an overview of the BCG Growth-Share Matrix, a tool created by the Boston Consulting Group in 1968 to help companies evaluate their product portfolio. The matrix plots products based on their market share and growth rate to categorize them as stars, cash cows, question marks or dogs. Stars are high growth, high share products that companies should invest in. Cash cows are low growth, high share products that provide cash flow. Question marks are high growth, low share products requiring analysis. Dogs are low growth, low share products that should be cut. The matrix helps companies understand where to invest or divest based on market attractiveness and competitiveness.
