About this Course

Duration 3 Days

A 3-day training course providing both a theoretical and practical overview of the Tripod Beta methodology, enabling delegates to support and conduct incident investigations and analyses

Tripod is a theory for understanding incidents and accidents, based on the Swiss Cheese model. It was developed to explain how and why incidents happen, and allow the root organisational causes and deficiencies to be uncovered and addressed. This 3-day training course will provide a theoretical overview of the Tripod Beta methodology and teach delegates how to apply this in practice, helping delegates uncover not just how an incident happened but also why it happened: the management controls that should have prevented it and the systemic organisational issues that can lead to future incidents.


Tripod Beta provides a structured way of thinking about why accidents happen and would be useful to anyone involved in managing risk and preventing unwanted events, such as:

  • Managers

  • Quality Assurance Engineers
