$2.$ You are a human resources manager at a multinational enterprise $($MNE$)$ headquartered in the United States, with subsidiaries in multiple countries, including Germany, India, and Brazil. The company has a strong set of HR practices shaped by its home country, particularly focusing on individual performance, merit$-$based rewards, and a formal hierarchical structure. However, the host countries have their own HRM norms: Germany emphasizes collective bargaining and employee co$-$determination; India focuses on relationship$-$building and informal decision$-$making; Brazil values flexibility and family$-$like work environments.

The headquarters is considering whether to integrate some of these foreign practices back into the US$-$based operations. Question: "How can the MNE effectively integrate HRM practices from its subsidiaries while maintaining the core values of its home$-$country HRM policies?
