This study identifies key potential users of high-performance computing within the Army science and technology community and develops a strategy to build an initiative that will help the Army compete effectively for Department of Defense computing resources. Particular attention was given to applications of HPC in biotechnology and biomedicine and modeling and simulation of complex battlefield wireless network communication systems.

Recommends an approach to improving the utility and accuracy of software cost estimates by exposing uncertainty (in understanding the project) and reducing the risks associated with developing the estimates. The approach focuses on characteristics of the estimation process (such as which methods and models are most appropriate for a given situation) and the nature of the data used (such as software size), describing symptoms and warning signs of risk in each factor, and risk-mitigation strategies.

The U. S. Global Positioning System (GPS), now the world's preeminent pointing, navigation, and tracking (PNT) system, will in the not too distant future be joined by the European Union's Galileo, a PNT system planned to be similar to GPS in function and performance. Will the two systems cooperate, providing users with the benefits of both, or will they compete? The authors assess the economic impact of competition and how the United States can address that competition, especially as it affects U. S. economic interests.

This title presents case studies from states with exemplary practices in information technology governance to determine best practices for California's IT program.
