The relationship between Workload, Teamwork, Situation Awareness, and Performance in Teams: A microworld study

摘要

In modern military organizations teamwork performance is central, yet the underlying factorscontributing to such performance are debated. The purpose of this paper was to investigate how severalknown teamwork measures relate to a prior model of operator performance (N?hlinder et al, 2004). Thisstudy expands this model to the team level and in the command and control domain. Specifically, thispaper studies the relationship between individual and team workload measures, situation awarenessmeasures, and performance measures in 18 two-person teams.The study has two major findings: Firstly, the various team cognition measures statistically cluster intofour meaningful concepts (workload, teamwork, situation awareness and performance).Secondly, a Structural Equation Model indicates that the relationship between the various individual andteam measures can be described in a model resembling the model found in previous studies (N?hlinder etal, 2004). In particular, the results show that the general workload in the microworld study has a negativeeffect on both teamwork and situation awareness. Teamwork, in turn, also affects situation awareness,which has major impact on performance.
