Starbucks has rapidly expanded from 17 coffee shops in Seattle 15 years ago to over 16,000 outlets in 50 countries. While global expansion provides opportunities for growth, it also poses challenges as Starbucks must adapt to new markets. As the US market becomes saturated with Starbucks locations, maintaining historic growth rates will be difficult. Starbucks is focusing on innovation like mobile ordering and expanding its food offerings to attract new customers and drive additional sales. However, concerns over employee satisfaction and treatment could impact Starbucks' customer service and brand image as it continues to grow globally.
