McDonald's business model is based on franchising, where franchisees pay licensing fees to operate McDonald's restaurants using the company's branding, training, and standards. This franchise model has been highly successful for McDonald's, with over 31,000 locations globally generating $22.6 billion in annual revenue. McDonald's competitive advantages include its strong brand recognition for fast service and cleanliness, standardized menus, and large global scale and real estate holdings compared to competitors like Burger King. However, McDonald's still faces competition and needs to continuously improve through strategies like advertising, expanding locations, training investments, pricing reviews, and making menu options healthier.
