Abstract
The increasing use of teams has called for more research that can provide deeper understanding of the factors that will enhance team performance. In particular, understanding team process is vital for effective team performance. Communication, as one component of team process, plays an important role for team coordination, monitoring, feedback, backup, and other teamwork components. In this paper, the change in communication intensity with increasing mission novelty is investigated and the types of communication that will lead to effective cooperative behavior are determined. In the study, twelve helicopter pilots are randomly assigned into six two-person teams. The team consists of a pilot and copilot, with each performing different roles and assuming responsibilities, and accordingly their access to information and control. Three missions with increasing level of difficulty are simulated using a computer game. The experiments are video-recorded and team communications are transcribed and analyzed. It is found that team communication intensity forms an inverted U shape relationship with increasing workload. The results also demonstrate that the better performing team used easy to understand and straightforward communication, which ends up being more accurate. It is also established that frequency count of classified statements in communications does not reveal as much critical information on team processes as content and time analyses. Finally, an assessment of the communications with a focus on team behaviour along a timeline reveals accuracy, phrasing and timing to be of crucial importance to team effectiveness.

Paper presented in the 8th South East Asia Ergonomics Society Conference, May 2005, Bali, Indonesia.

Abstract
Tactical Data Link System is a form of Network Centric Warfare (NCW) that is used to increase war-fighting capabilities. These systems are designed to equip pilots with real time information through digital communication. With the benefits offered by these systems, many Air Forces have incorporated them into their modern war fighters. Previous studies have reported that team performances are enhanced and workload levels are decreased with the implementation of the systems. However, little is known of the effect of the systems on team processes. As evaluation of the effectiveness of communication is essential for better understanding of team processes, this study aims to assess team communication intensity with the introduction of Tactical Data Link Systems at different workload levels. Twelve helicopter pilots participated in this study. Experiments are conducted in a simulated environment, where teams of helicopter pilots (pilots and copilots) execute three tactical missions with increasing difficulty. The results show that team communication intensity varies with different workload conditions. It is also found that team communication intensity deviate from the inverted U trend found in traditional systems when Tactical Data Link Systems are used across increasing workload conditions. It is thus concluded that these systems facilitated higher team coordination and monitoring behavior, especially during time compressed situations, where verbal communications are limited.
