Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. AbstractSpace and Naval Warfare Systems Center, San Diego's (SSC-SD) Command 21 project, sponsored by ONR, is addressing how information technology can be designed to best facilitate information production, consumption, and management. For the past several years, the focus of the Command 21 effort has been the development of Knowledge Web (K-Web), which utilizes Web technologies to share operationally relevant information. In K-Web, data is processed and stored by 'producers' in a way that represents meaningful knowledge to 'consumers'. Use and utility of K-Web at the Global 2000 war game, were reported at last year's CCRTS. K-Web was implemented on USS Carl Vinson in May 2001, for use during deployment. Upon the ship's return, interviews of users were conducted, focusing on use and utility of K-Web tools, products, business rules and training materials. The interview data indicate K-Web as invaluable for asynchronous, distributed dissemination of operational information. Additionally, automaticallycollected data were analyzed for patterns of use. Quantitative and qualitative data enabled assessment of how the current K-Web concept and technologies support users' requirements within operational environments. These analyses were also compared to analyses from the war game environment. IntroductionAs technology increases the speed and ease of information exchange, the problems associated with information production, consumption, and management also increase. Effective commandlevel decision-making requires a high level of situation awareness (SA) (Endsley, 1995). To support improved SA, information must be made available in a format that is meaningful and useful for application to real-world problems; in other words, information must be transformed into knowledge. Space and Naval Warfare Systems Center, San Diego's (SSC-SD) Command 21 project, sponsored by ONR, is addressing how information technology can be designed to best facilitate information production, consumption, and management in support of the needs of senior decision makers and their staff in military command centers.
