Terrorism and the measures needed to prevent terrorist attacks pose a central policy challenge for the U.S. To meet this unprecedented challenge, the U.S. has great technological assets. What is needed are mechanisms to help the government draw on these strengths in a timely and effective fashion. To do so, the government needs to reach out to university researchers, national laboratories, small, high-tech businesses and leading corporations. One of the most effective ways to do this is through public-private partnerships. To link the lessons of the National Academies study on "Government-Industry Partnerships" to this critical national interest, the Academy organized a conference to bring the lessons of its analysis to bear on the war on terror. By encouraging policy attention to examples of effective public-private partnerships (in particular, the need for clear goals and regular assessments), this report contributes to a better understanding of the potential partnerships to bring new security-enhancing technologies and equipment to the market in a cost-effective and timely manner.
