The Boston Consulting Group (BCG) matrix is a strategic planning tool that helps companies to evaluate their product portfolio based on two dimensions: market growth rate and relative market share. The matrix is divided into four quadrants, each of which represents a different strategic recommendation.
The four quadrants of the BCG matrix are:
1. Stars: These are products that have a high relative market share and are in a high-growth market. Companies should invest in these products to maintain their market share and take advantage of the growth opportunities. An example of a star product is the iPhone for Apple.
2. Cash cows: These are products that have a high relative market share but are in a low-growth market. Companies should milk these products for cash flow and invest in other products with higher growth potential. An example of a cash cow product is Coca-Cola, which has a high market share in a mature market.
3. Question marks: These are products that have a low relative market share but are in a high-growth market. Companies should invest in these products to try to increase their market share. If they are unsuccessful, they may need to divest the product. An example of a question mark product is Tesla's solar panels.
4. Dogs: These are products that have a low relative market share and are in a low-growth market. Companies should divest these products if they cannot find a way to turn them around. An example of a dog product is Blockbuster, which was a video rental store in a declining market.
The BCG matrix is a useful tool for companies to evaluate their product portfolio and make strategic decisions about where to invest resources. By analyzing their products based on market growth rate and relative market share, companies can identify which products to invest in, which to milk for cash flow, which to try to turn around, and which to divest.
