What classification in the BCG Matrix represents a key source of internal cash generation?

The classification in the BCG Matrix that represents a key source of internal cash generation is referred to as Cash Cows. Cash Cows are products or business units that have a high market share in a mature industry. They are typically characterized by their ability to generate more cash than they consume due to low investment needs. This excess cash can then be used to fund other areas of the business, particularly those that may require additional investments, such as Stars or Problem Children.

Stars, while promising in terms of growth and market share, often require significant investment to maintain their position and exploit their growth potential. Dogs typically have low market share in a low-growth industry, making them less reliable for cash generation. Problem Children, or Question Marks, might need substantial resources to grow and may not yet be generating positive cash flow. Therefore, Cash Cows are strategically important because they provide a steady financial foundation for an organization, allowing for reinvestment into other business opportunities.
