Display design for command centers often focuses on the best methods to display information. An even more fundamental issue, however, is the design of the 'information space' for the command center, defined as the set of information that is needed by each individual in order to perform their individual and team tasks. Instead of being systematically designed, the information infrastructure and physical layout of command centers often evolve over time as new technologies are added, new positions created, and new connections and communication links are established within and between command nodes. This paper presents a systematic, quantitative method for designing the information space for a command center to best support team performance, based on the communication and information structure of the team. Using information about the team's communication patterns and information needs, we apply model- based principles to generate candidate designs for the physical layout of the command center and to develop designs best suited to the team structure.
