The Federal Railroad Administration (FRA) Office of Research, Development, and Technology’s Human Factors Division sponsored TrueSafety Evaluation and Perigean Technologies to develop an Expertise Management (EM) framework for identifying, capturing, and transferring critical areas of expertise for safety leadership positions. The EM Framework is a set of processes and methods for managing expertise–from identifying where expertise is centered, to methods for helping experts articulate what they know, to approaches for engaging other professionals to accelerate their own proficient performance. The EM Framework uses Cognitive Task Analysis (CTA), which previous FRA-sponsored initiatives have found valuable in eliciting expertise.
