The prevalence of the use of teams in a variety of occupations and environments has increased the importance of investigating the processes involved in their performance. However, in the past, there have been few methodologies available for the investigation of team performance. The present manuscript attempts to contribute to this area of research by describing the rationale underlying the use of computer-based simulations in research on team performance. This is followed by a review of the networked simulations that are currently being used in team-performance research. This review emphasizes the capabilities provided by the networks and the types of research concerns for which they are effective. Finally, the application of this technology to the broader study of group performance is discussed.Because teamwork is prevalent in a number of occupations (e.g., fire-fighting, aircrews, and medicine), the ability of teams to work effectively has become a vitally important issue. In fact, Watson (1990) states that the effective use of teams is "America's best hope" for competition in the worldwide marketplace. It has been noted that technological developments and global competition have placed added emphasis upon understanding the processes and performance of teams because many tasks are often beyond the mental and physical resources of one individual (Salas, Dickinson, Converse, & Tannenbaum, 1992). Cannon-Bowers, Oser, and Flanagan (1992) cite three reasons underlying the increased importance of using teams in industry. The first is that there are critical tasks that cannot be accomplished by one individual alone. The second is the belief that groups will together perform better than single individuals. Furthermore, certain critical tasks often benefit from the redundancy offered by the use ofteams (e.g., nuclear power plant operators). The third is that group structures have developed in response to the humanistic movement in industry; that is, it is argued that the use of groups and work teams increases the source of significance and responsibility of individuals in relation to their occupations. Cannon-Bowers et al. (1992) concluded, in their review of the literature on the use of work teams in industry, that "work groups are important and offer enoughThe views expressed in this paper are those ofthe authors and do not reflect the official position of the Department of the Navy, the Department of Defense, or the U.S. Government.

Despite the critical role that teams play in industry, however, science has made woefully little progress in understanding the factors that contribute to effective team performance. In fact, reviewers in this area have severely criticized the available knowledge rega...
