Final answer:
The structure of global sourcing organizations is most effective when it varies depending on the location of key suppliers and company operations.
Step-by-step explanation:
The structure of global sourcing organizations is most effective when it varies depending on the location of key suppliers and company operations. This means that the effectiveness of the structure will depend on the specific circumstances and needs of the organization. For example, if a company relies heavily on suppliers in a certain region, it may be beneficial to have a centralized structure to manage those relationships. On the other hand, if the company operates in multiple countries with different regulations and market conditions, a decentralized structure that allows for local decision-making may be more effective.
