Simon (together with SAM - web-based application for scenario management) is a tool to help plan, execute and analyze medical exercises. Simon is the mobile module for medical exercise management. Primary users are instructors/case-managers, who are responsible for assisting and helping out medics, who are participating in an exercise. Simon gives instructors a clear overview of the scenario, simulated patients, the necessary activities for them and provides a thorough overview of the treatment path. It also provides the possibility for the instructors to communicate with each other or the exercise coordinator
