Fidelity analysis is the means by which training requirements are translated to hardware requirements for training device design and acquisition. However, there are few rigorous, analytical approaches to this important analysis step. Current practice is dominated by the engineering approach, which focuses on maximizing technology content based on the subjective inputs of subject matter experts.

This paper describes a structured methodology for linking training requirements developed through the ISD process with fidelity requirements in order to optimize hardware design for simulation systems. While new, it has proven its utility in applications to two aircraft mission crew simulators and is currently being applied in development of the Naval Aviation Simulation Master Plan. Lessons learned in these applications will be discussed.
