The MAA has intentionally remained at arm’s length, in order to encourage the development of good practice by the user community, whilst keeping a Regulator’s oversight to ensure that the work implemented remained within the bounds of RA 1210. There has been a significant investment in the translation of current risks from the traditional risk register into the BowTie format, and training key personnel in a revised way of working. Early adopters have been working on its implementation for several years and are continuing to make significant developments in the way BowTie is utilised and how the software is implemented. Of the 6 ODH’s that cover UK military flying, 5 have made a commitment to using BowTie within their respective Air Safety Management System (with the 6th now developing a capability). For this reason, BowTie has found utility in many high-risk sectors from Oil and Gas, Chemical safety and mining through to the rail industry and Aviation sector (both civilian and military). For several years, the majority of ODH’s have been developing risk management systems that embrace the BowTie risk assessment methodology as it is believed that, when used correctly, it can provide an easier to interpret and more holistic view of overall risk exposure. With the publication of RA 1210 Issue 4, Operating Duty Holders ( ODH’s) have been given more latitude in the way in which they choose to record and document risk within their area of responsibility allowing the scope to incorporate and develop good practice. It is widely regarded as a suitable visual tool to keep an overview of risk management practices, rather than replacing existing processes or systems. The exact origin is unclear but the mainstream use started in the aftermath of the Piper Alpha disaster with Royal Dutch/Shell adopting the methodology as the company standard for analysing and managing risk. BowTie finds its roots in the chemical industry course notes for a lecture on hazard analysis given at the University of Queensland in 1979.
