Interagency Collaboration: Key Issues for Congressional Oversight of National Security Strategies, Organizations, Workforce, and Information Sharing, Report to Congressional Committees [open pdf - 3MB]
"While national security activities, which range from planning for an influenza pandemic to Iraq reconstruction, require collaboration among multiple agencies, the mechanisms used for such activities may not provide the means for interagency collaboration needed to meet modern national security challenges. To assist the 111th Congress and the new administration in developing their oversight and management agendas, this report, which was performed under the Comptroller General's authority, addresses actions needed to enhance interagency collaboration for national security activities: (1) the development and implementation of overarching, integrated strategies; (2) the creation of collaborative organizations; (3) the development of a well-trained workforce; and (4) the sharing and integration of national security information across agencies. This report is based largely on a body of GAO work issued since 2005."
