Final answer:
In the BCG matrix, SBUs with high market growth but low market share are referred to as Question Marks or Problem Children. They require significant analysis and decisions regarding future investment or divestment.
Step-by-step explanation:
SBUs or Strategic Business Units with a high share of high-growth markets but may not generate enough cash to support their own high cash demands for future growth are referred to as Question Marks or Problem Children in the Boston Consulting Group (BCG) matrix. These are businesses or products that operate in a high-growth industry but have a low market share. They require careful analysis to determine whether investment is warranted to increase market share or whether they should be divested. The BCG matrix is a tool used for portfolio analysis in strategic management and marketing.
Understanding the placement of an SBU as a Question Mark is critical for resource allocation in business strategy. Managers must decide whether to invest in these SBUs to become market leaders (Stars), or to divest, thereby freeing up resources for more promising opportunities. The decisions surrounding Question Marks are some of the most challenging ones faced by strategic planners.
