RR679 - Review of human reliability assessment methods

Human reliability assessment (HRA) involves the use of qualitative and quantitative methods to assess the human contribution to risk. There are many and varied methods available for HRA, with some high hazard industries developing 'bespoke', industry focused methods.

It was considered that it would be useful for HSE to be up to date with developments in the field of quantitative HRA methods and to have knowledge of the capability of the tools and an understanding of their strengths and weaknesses.

Therefore, this project was commissioned to further HSE knowledge and expertise, and to form a view on the 'acceptability' of the various tools for use in risk assessments.

This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.
