Summary: To protect the nation from terrorist attacks, homeland security stakeholders must more effectively work together to strengthen the process by which critical information can be shared, analyzed, integrated and disseminated to help prevent or minimize terrorist activities. The success of a homeland security strategy relies on the ability of all levels of government and the private sector to communicate and cooperate effectively with one another. Activities that are hampered by organizational fragmentation, technological impediments, or ineffective collaboration blunt the nation's collective efforts to prevent or minimize terrorist acts. The challenges facing the homeland security community require a commitment to focus on transformational strategies, including strengthening the risk management framework, refining the strategic and policy guidance structure to emphasize collaboration and integration among all relevant stakeholders, and bolstering the fundamental management foundation integral to effective public sector performance and accountability. Implementation of these strategies along with effective oversight will be necessary to institutionalize and integrate a long-term approach to sustainable and affordable homeland security.
