How would you classify a business that is struggling for market share in a rapidly growing industry?

In the context of a business struggling for market share in a rapidly growing industry, it is classified as a "Question mark." This classification is part of the BCG (Boston Consulting Group) matrix, which helps in understanding a firm's portfolio of products or business units.

A business categorized as a "Question mark" typically has low market share in a high-growth industry. This indicates that while there is potential for growth and profitability, the company has not yet established a strong presence in the market. As such, it faces uncertainty regarding its future performance and requires strategic decisions about whether to invest in its growth to gain market share or to withdraw from that market altogether.

In contrast, a "Star" represents a business with both high market share and high growth potential, while a "Cash cow" indicates a business with high market share in a low-growth industry, typically generating consistent profits. A "Dog" refers to a business with low market share in a low-growth industry, often seen as a poor performer. Therefore, since the business in question is in a high-growth industry but struggling with market share, it fits the "Question mark" category, highlighting its uncertain position and the critical decisions needed to enhance its competitiveness.
