Search the Internet to identify three highly decentralized companies. Based on the information you find on each, either determine directly or infer the types of responsibility centers used by these companies. Also, determine or speculate about whether the companies use transfer prices or allocation of costs for intracompany transfers of services. Prepare a report on your findings and inferences. In cases for which you had to infer, explain what information or reasoning led you to that inference. Why is decentralization appropriate for some companies but not for others?
