How would you describe McDonald’s business strategy?

What are the foundations of its competitive advantage

(what are the sources of its success)?

People are McDonald’s most important asset. The company’s success depends on the satisfaction of its customers, which begins with workers who have the attitudes and abilities required to work efficiently and provide good customer service. To execute its growth strategy, McDonald’s has identified people as one of its three global corporate strategies.
McDonald’s claims that as an employer, it wants “to be the best employer in each community around the world.”82 It also makes a “people promise” to its employees that “we value you, your growth, and your Contributions.”83 Its five “people principles” reflected by its human resource strategy are respect and recognition; values and leadership behaviors;
competitive pay and benefits; learning, development, and personal growth; and ensuring that employees have the resources needed to get the job done
