Step-by-step explanation:
Rugman and D'Cruz have developed an alternative framework to Porter's five forces model called the Flagship model. Their approach is based on business networks and aligns with complex theories of international relations, such as core countries and periphery countries, and the detailed analysis required in anti-trust regulation. The Flagship model considers that firms do not necessarily cluster together in a market based on price, service, or quality, acknowledging a more nuanced competitive landscape that includes different strategies like building brand name or reputation for good service.
