McDonald's brand value declined from $42 billion in 2014 to $39 billion in 2016 due to increasing prices, strong competition, and declining customer traffic. To combat this, McDonald's introduced strategies like co-branding, value menus, customized orders, and technology. Recent changes such as menu simplification, premium sandwiches, improved service, and delivery have helped performance. To further improve, McDonald's could add healthier options and more ordering methods to attract millennials.
