PERFORMANCE MEASURES FOR HUMAN FACTORS ENGINEERING EVALUATION OF EARL EQUIPMENT
Abstract
A simple measurement design is inadequate for field testing of teams. Observations must be structured to detect separate patterns of performance across multiple variables, individual team members, and various subtasks. Human observers at the field site cannot alone record this wide range of data at the pace of team performance. Data recording equipment, particularly videorecorders, assure a more adequate and objective data collection. Performance of certain team tasks, generally those requiring individual initiative in coordinating activity, may be significantly altered by the wearing of the protective masks. Other tasks of a repetitive drill nature may be much less affected. Even very meticulous testing during field training activity may fail (because of the 'slack time' and indirect motivations inherent in the practice environment) to reflect validly potential decrements in a tactical environment. For 105-mm howitzer crews specifically, there will probably be no consistently critical performance problems while wearing protective masks, although the team's normal pattern of oral intercommunication is definitely disrupted.
