Investigation Methodology

We Prefer Tripod BETA

A scientifically grounded methodology — used by most major industries — designed to uncover the root organisational deficiencies behind every incident.

Tripod BETA is an incident investigation and analysis methodology designed in line with the human behaviour model. Developed in the early 1990s, it was explicitly created to help investigators understand the influencing environment and uncover root organisational deficiencies that allowed an incident to happen.

Unlike typical end-user tools, Tripod BETA requires certain skills obtained through training and experience. It is a high-end analysis tool capable of handling high-risk and complex incidents — applying strict logic with a full range convention, making outcomes reliable and replicable.

The methodology banks on the principles of Hazards and Effects Management, Barrier Based Risk Management and Human Error Theory. The tool allows free formulated Underlying Causes categorised into 11 distinct Basic Risk Factors — enabling statistical comparison, baselining and benchmarking.
