Abstract
A prototype decision support system (DSS) was developed to enhance Navy tactical decision
making based on naturalistic decision processes. Displays were developed to support
critical decision making tasks through recognition-primed and explanation-based reasoning
processes and cognitive analysis of the decision making problems faced by Navy
tactical officers in a shipboard Combat Information Center. Baseline testing in high intensity,
peace keeping, littoral scenarios indicated that experienced decision makers were
not well served by current systems, and their performance revealed periodic loss of situation
awareness. A study is described with eight, expert Navy tactical decision making
teams that used either their current system alone or in conjunction with the prototype
DSS. When the teams had the prototype DSS available, we observed significantly fewer
communications to clarify the tactical situation, significantly more critical contacts identified
early in the scenario, and a significantly greater number of defensive actions taken
against imminent threats. These findings suggest that the prototype DSS enhanced the
commanders’ awareness of the tactical situation, which in turn contributed to greater confidence,
lower workload, and more effective performance.
