Use a “show me what happened” approach to really understand what happened.
The key objectives of an incident investigation typically relate to the activities, positions and movements of people, the location and use of tools, equipment and materials and the location and safety equipment and PPE. Models and props allow a “show me what happened” method of inquiry rather than the potentially flawed “tell me what happened” approach.
Hands-on models encourage focus and level of engagement from witnesses and participants that can enable an enhanced investigative process - such as re-enacting the circumstances surrounding the incident and the series of steps leading to the incident. Using models and props enable these steps and phases to be examined in- or out-of-sequence to identify and exclude possible conjecture or bias.
