This paper reviews the development of a measurement and feedback system using a systems approach to design in an evolving training setting. The WarFighter Feedback-System is a prototype automated feedback system developed for the Battle Command. Training Program. The goal of the development was to provide a means to prepare and present diagnostic feedback on unit performance to training audiences during After Action Reviews and to support the Army's requirement for systemic feedback on planning and decisionmaking for Division and Corps headquarters. The intelligence slice of division operations was selected for the evaluation and demonstration of the principles associated with training performance measurements of collective tasks. The Intelligence Battlefield Operating System is a subset of Command and Control (C2) comprised of several interdependent collective and small group tasks. The nature of these tasks and the measures of performance associated with them can be organized to support analysis and feedback in various training settings. Change management approaches and extension of this applied research to the broader context of C2 are the major reported findings.
