Final answer:
ACME Corp. is likely using an international division structure to manage its specialized international operations efficiently, which aligns with the complexities of global assembly lines and the economic trend of splitting up the value chain seen in multinational corporations.
Step-by-step explanation:
If ACME Corp. has concentrated its human resources with international expertise into one unit which serves as the central point for all information flow related to international operations, it is most likely using an international division structure. This organizational structure allows companies that are primarily domestic to manage operations in other countries effectively while still maintaining a clear separation between domestic and international units. This structure supports specialization in areas such as human resources, finance, and product development, which are tailored to the needs of international markets.
As we see in global corporations like Apple, international business activities often involve a complex web of international transactions such as designing, sourcing components, and assembling products in different countries (referred to as the global assembly lines). This modality fits well within the context of an international division structure, as this structure provides the framework necessary to manage such complex international operations efficiently. The importance of specialization is further emphasized in the world economy, especially with the trend of splitting up the value chain which allows different parts of the production process to be outsourced to various countries, maximizing efficiency and profitability.
