What is the only way to grow utilizing existing services and markets?

Focusing on market share is the only strategy listed that specifically emphasizes growth within existing services and markets. By increasing market share, a business aims to attract more customers from its current target audience or competitors. This involves implementing strategies such as effective marketing, enhancing customer service, or competitive pricing without needing to venture into new products or services.

Increasing revenue is important, but it can occur through various methods, including introducing new products or improving existing ones. New product development inherently implies creating new offerings, which is outside the scope of existing services and markets. Customer satisfaction is crucial for retaining clients and enhancing loyalty, but it does not alone guarantee growth; instead, satisfied customers can aid in increasing market share by recommending the business to others. In summary, focusing on market share is the most direct approach to fostering growth through the lens of existing offerings and customer bases.
