7. Los Alamos National Laboratory PWL 7-8/2/01 NNSA/DP DOE DOE has Clarified its Governance of LANSCE “Assign … Defense Programs as the Organizational entity with corporate responsibility and accountability for strategic integration of all three program offices using LANSCE. This approach applies both to the short- term objective of facilitating IPF construction and the long-term goal of reliable accelerator operations.” from Memorandum from the Deputy Secretary of Energy to General Gordon 12/21/2000 Single Point Accountability Single Line of Authority Participation of all stakeholders Authority and Responsibility chain includes accountability for those controlling the resources LANL NE SC LANSCE NNSA/DP LANSCE Program Manager NNSA/DP LANSCE Program Manager Authority/Responsibility Funding Funding Coordination
