Simulations While critical in training employees on actual work experiences, simulations are probably even more popular for employee development.” The more widely used simulation exercises include case studies, decision games, and role plays. Employee development through case-study analysis was popularized at the Harvard Graduate School of Business. Taken from the actual experiences of organizations, these cases represent attempts to describe, as accurately as possible, real problems that managers have faced. Trainees study the cases to determine problems, analyze causes, develop alternative solutions, select what they believe to be the best solution, and implement it. Case studies can provide stimulating discussions among participants, as well as excellent opportunities for individuals to defend their analytical and judgmental abilities. It appears to be a rather effective method for improving decision-making abilities within the constraints of limited information.
