Final answer:
The correct answer is C. The advantage not typically offered by a regional management center is considerable cost savings, as their primary function revolves around coherent regional planning and decision-making, not directly cost reduction.
Step-by-step explanation:
The advantages that a regional management center can offer a company include all the following except considerable cost saving. While regional management centers can provide pan-regional decision making, coordinated regional planning, coordinated control, and coordinated decision making, they are not inherently designed to generate considerable cost savings as a primary advantage.
Other mechanisms like economies of scale or operational efficiencies can lead to cost savings, but these are not the direct function of a regional management center, which is more about managing resources effectively across different areas and ensuring coherent strategies are implemented at a regional level. The aim of regional management is to unify decision-making processes and standards which can lead to better preparedness for things like regulatory compliance and market competition. Moreover, the cost savings are not guaranteed and depend on how efficiently the regional center is managed and whether it can effectively leverage regional synergies.
