If we are focusing on companies and not countries, we can say that outward-oriented strategies are more likely efficiently allocate funds than inward-oriented strategies for several reasons. One reason would be that every new outward allocation or expenditure is, at first, non-essential and will be thoroughly vetted and analyzed upon being implemented and before being continued.
For instance, if a company decides to hire an outside agency to clean the facility, that agency will be monitored closely for efficiency and cost. This is an outward strategy, a form of out-sourcing.
If the company instead chose to focus on improving the efficiency of the current janitorial staff, more internal staff would be required to work both on and in the janitorial department. Increasing the effectiveness and decreasing the costs of an existing department will be logistically more difficult, and may present fewer options for improvement.
