The first challenge for a global business is not with the implementation of international strategy but with the creation of the strategy. An international strategy must be comprehensive and this would make decision making difficult especially for manager. There are a lot of global businesses out there, but only few have proper strategy.
The next challenge now is on the implementation of this strategy. Implementing international strategy requires somebody to have extraordinary and right leadership skills. Otherwise, the strategy could not be justified. This area of business management should be handled by professionals who are a graduate of business management. This is not an easy duty, so somebody expert should handle this duty.
There are also risks involve in using these strategies. With proper planning, this can be resolved. An international business must be prepared enough even from the creation of international strategies and with the implementation. This is a challenge that every international business must face.
