This research focused on changes in supply chain responsibilities. The primary research question was: What are the reasons (drivers) for major changes in supply chain responsibilities? Over 200 such changes, comprising 158 additions and 44 deletions, were documented in the research. The findings are based on 10 case studies in large multi-business unit companies, seven headquartered in the United States and three in Europe, representing a variety of industries. Findings indicated three drivers of change for supply chain responsibilities. The chief purchasing officer and his or her staff members had a great deal of influence, particularly in additions to category 1 (acquisition of specific organizational needs) and category 2 (activities within the total supply chain).
