Human Reliability Analysis

Human Reliability Analysis (HRA) refers to a group of methods used to predict the reliable performance of people who operate equipment and systems. It is not to be confused with Human Error Analysis (HEA) which retrospectively analyses the reasons for errors that have been made in the past. HRA can be used to assess the risk of human failure associated with future or modified systems, or with changes to procedures.

The Keil Centre can help organisations to consider the most relevant HRA approach for their situation, and to apply it within their own organisation. For example, qualitative approaches describe what a potential human failure could be and how this could be mitigated. Quantitative approaches tend to use a mixture of formulae and judgement to predict the likelihood of failure .They are therefore able to predict the likelihood of human failure and advise organisations how frequently this could occur.

Some description


Following the application of such HRA techniques to identify potential human failures, we can identify measures to reduce the likelihood of these failures occurring. These measures can include:

  • Design of the system or components
  • Design of procedures
  • Training interventions

Our Ergonomists all have significant industry and equipment design experience covering control rooms and human-machine interfaces in a wide range of industry sectors. They use recognised HRA methods that are mature in their use and that meet industry and regulatory guidelines on HRA techniques.
