Bowtie Methodology

A Guide for Practitioners

Bow Tie Methodology (BTM) consists of two methods, Fault Tree Analysis (FTA) and Event Tree Analysis (ETA), which are connected by a single event. The methodology is holistic and provides the tools and pre-event analysis, which is also called the risk calculations, and post-event analysis, also called the risk mitigations, of quality and safety related events. There are plenty of articles or chapters on this methodology, however there is no book that covers everything in one place. The book is filled with examples taken from the aviation industry and elaborates theory implemented in practice, which gives quality and safety practitioners a guidance on how to use and apply BTM in practice.
