Arendt Jr., Michael JamesDoD's supply-chain supports over 1 million uniformed, civilian, and contract employees, manages over $90 billion in inventory, and maintains some 15,000 aircraft, 300 ships, and 30,000 combat vehicles. The supply-chain is undeniably the backbone of DoD operations, ultimately enabling it to achieve mission success under a variety of situations. In recent years, the DoD has pursued numerous initiatives for the purposes of improving its supply-chain. Motivations to seek improvements (such as asset tracking, reduced errors, etc.), decreased costs, and increased responsiveness for the warfighter have been plentiful; however, measured improvement thus far has been difficult to ascertain. It is the intent of this research to establish a framework to enable DoD to use industry best practices and process improvements from the Supply Chain Operations Reference Model (SCOR) as a tool for Defense supply-chain modernization efforts. To accomplish this, the dissertation will address the following research questions: 1. How can the Supply Chain Operations Reference (SCOR) model be adapted for use as an enterprise-level tool by the United States Department of Defense? 2. Once adapted, what barriers to the implementation of this new tool exist? 3. How can these barriers be overcome?DissertationPublic policyDepartment of DefenseMilitary LogisticsOrganizational ChangeSCORSupply Chain
