Integrating Safety Management through the Bowtie Concept A move away from the Safety Case focus

Acfield, A.P. and Weaver, R.A.

To ensure that safety processes such as risk management, change management and incident investigation deliver maximum value, it is essential that they are effectively integrated. As well as providing a means to represent risk, the Bowtie concept also provides a strong basis for integrating these safety processes, both internally within an organisation and cross-organisationally. This paper provides an overview of how these processes can be integrated, why this integration is essential and why a change in focus from traditional Safety Cases to Bowtie Risk Management is needed within the safety engineering industry. As well as this, the paper describes in detail how a Bowtie Risk model can be used at the heart of safety requirements elicitation and a safety change management argument. The aim of the paper is to effectively demonstrate that a risk-based approach to safety management, using the Bowtie concept, provides an effective means of achieving both this integration and shift in safety argument methodology.
