According to the case study, alpha approach try to make their employee think like the CEO. It can be shown that alpha is using Poly-centric Approach because in running a company located in a country they will recruit people from the country where he runs the company, because they thinks that people from a country understand the culture and conditions of his own country better.
And I highly recommend Geo-Centric Approach, because it trying to find the best people for important jobs through the organization regardless of nationality. This policy emphasizes the importance of individual competence regardless of race or nationality.
