ethnocentric model, polycentric model, or global model?

The most appropriate model for staffing each group will depend on the particular situation. The ethnocentric model is best suited for companies that prioritize standardization and central control of their operations, as it relies heavily on home country personnel. The polycentric model is better suited for companies with a more decentralized approach to doing business, as it allows them to tap into local expertise while maintaining some level of control over international operations. The global model is optimal when a company wishes to operate independently in various locations, allowing them to recruit and retain talent from around the world without needing approval or input from corporate headquarters.
