Pursuant to a request by the Department of Defense, the National Research Council (NRC) convened a study committee under the auspices of the Computer Science and Telecommunications Board (CSTB) to assess the nature of the . national investment in software research and, in particular, to consider ways to enhance the knowledge and human resource base needed to design, produce, and employ software- intensive systems for tomorrow’s weapons and operations systems. Many organizations are facing the combination of increasing system scale and increasing complexity of software-intensive systems. However, the com- pelling need to interconnect them to realize DoD’s vision of “net-centric warfare” exacerbates.
