The only way to deal with the increased complexities of the future in command and control, the huge amounts of data available, reduced manpower and cost goals, and training in tactical operations is to follow a human centered design process. It is time we design the hardware/software system to support the people instead of asking the people to compensate for the hardware/software system. This will only be accomplished by institutionalizing an integrated human systems engineering process that fully accounts for every person in the system. Use of this process will be critical to future complex system designs and in particular to integrated command centers. In addition to engineers following the process, engineering environments must facilitate a human systems engineering approach. A human systems engineering process and a prototype engineering environment, the Human Centered Design Environment which is currently under development, are described.
