Simulation-based tactical training exercises are ideal settings in which to evaluate performance. The capability to record the second-by-second behavior of participants, the state of supporting equipment, and the location of entities in the problem provides an opportunity to verify team and individual proficiency, and to identify root cause of substandard performance. However, responsibility for determining cause and effect in tactical scenarios is typically left to the expert instructor. In dynamic, fast-paced warfare areas, such as air-to-air combat, the burden on the unaided expert instructor to monitor, record, and assess the interactions and circumstances that determine mission success, is substantial. This is an area where appropriate technology might help the instructor to improve the evaluation of performance.

The Debriefing Distributed Simulation Based Exercises project (DDSBE), an ONR-sponsored 6.3 research and development project, tested alternative technologies for collecting and integrating performance information to aid in the preparation and delivery of post-scenario after action reviews (AARs). The project's objective was to provide the information that instructors need, when needed, in a form that supports rapid evaluation. This paper presents a comparison of different performance data collection, analysis, and debriefing systems, and the performance information they make available to instructors in the context of two distributed training research systems. The first system, built to support the DDSBE research effort, analyzed the performance of two E-2C Naval Flight Officers (NFOs) and F/A-18 Sweep Lead during an air-to-air engagement. Human observers and an automated data collection component collected performance data. The second system, a two-ship F/A-18 simulation built to support training research by The Boeing Company, collected and analyzed performance data for tasks performed by the Escort Lead and Strike Lead during an engagement. The paper presents and compares methods for integrating and presenting the multiple streams of performance information available to the instructor.
