Explain Sustainable competitive advantage and give an example?

Sustainable competitive advantage refers to a unique advantage that a company holds over its competitors, which is difficult to replicate and can be maintained over time. This could stem from factors like proprietary technology, strong brand reputation, or exclusive access to resources. For example, Coca-Cola has a sustainable competitive advantage due to its iconic brand identity and extensive distribution network, making it challenging for competitors to match its market presence and customer loyalty.
