McDonald's uses a strategy of cost leadership through standardized processes and vertical integration. It focuses on market penetration by opening new locations globally. While maintaining consistency, McDonald's has also developed new products and markets over time. Most McDonald's locations are now franchised, which allows for local autonomy while maintaining the corporate brand and operational expertise. Franchising has supported McDonald's continued growth worldwide. Maintaining core consistency does not require keeping all products and processes the same - with a strong foundation, McDonald's has innovated new offerings while retaining customer familiarity.
