BCG GROWTH-SHARE MATRIX

Summary

The BCG Growth-Share Matrix is a strategic planning tool developed by Boston Consulting Group that helps companies evaluate their business portfolio by plotting business units on a 2x2 grid. The vertical axis represents market growth rate (high vs. low), while the horizontal axis represents relative market share (high vs. low). This creates four quadrants: Stars (high growth, high share - invest heavily), Cash Cows (low growth, high share - milk for cash), Question Marks/Problem Children (high growth, low share - decide whether to invest or divest), and Dogs (low growth, low share - consider divestiture). The matrix helps managers allocate resources and make strategic decisions about which business units to prioritize, maintain, or eliminate.

Usage Context

This term is crucial when studying strategic management, portfolio analysis, resource allocation decisions, and corporate strategy. Students will encounter it when learning about multi-business corporations, strategic planning processes, and how companies decide where to invest their resources across different business units or product lines.

Common Confusions

• Confusing absolute market share with relative market share (BCG uses relative market share)
• Thinking that Dogs should always be divested immediately without considering other factors
• Assuming that all Stars will automatically become Cash Cows
• Misunderstanding that Question Marks require the most strategic decision-making
• Believing the matrix provides definitive answers rather than a framework for analysis
• Confusing market growth rate with company growth rate
