I believe Alpha used a POLYCENTRIC approach to maximize the number of workers by allowing each of them to take their responsibility on their behalf. It emphasizes localization and decentralization of decision making in different countries.
by adopting this kind of approach , they came to know the importance of local responsiveness in managing their own global workforce. This approach enable them to leverage the knowledge , skill and expertise of local employees ,adapt to local market conditions and build strong relationship with local stakeholders
