Evidence Collection Training and Resources

Base your investigation on facts, not assumptions.

TapRooT® offers multiple options for evidence collection training and resources. An investigation is an exercise in fact-finding, determining with credible information what happened with respect to an incident or accident. Evidence collection is the most time-intensive task in any investigation so jumping to analysis is tempting. However, developing corrective actions based on assumptions won’t stop repeat incidents.
