Human Factors Risk Management Software for the Power Generation Sector: SHERPA Demonstration

The Power Generation Industry is a safety critical sector that needs assurance that the risk of human error is as low as reasonably practical. The Human Factors Risk Manager software (recently renamed SHERPA - Systematic Human Error Reduction and Process Analysis) is used to analyse tasks, identify potential human error, analyse the drivers of that error and produce risk-informed operational procedures. This video demonstrates the potential of the software using a case study from the Power Generation Industry, but HRA also have a depth of experience in Process, Power Generation, Rail Transport, Aviation, Healthcare and Marine Industries. The SHERPA software allows the task to be easily broken down into different levels of detail (using Hierarchical Task Analysis (HTA)). This analysis allows one to produce very effective procedures which provide an overall structure to task and make them easier to understand. There are four main parts to the process which are demonstrated in the video: • Conducting a Hierarchical Task Analysis (HTA) of the task • Identifying the failures that can occur • Identifying the factors that can influence the failures • Creating a procedure based on the analysis The analysis focuses on carrying out on-load generator Brush gear maintenance, and it begins with a Hierarchical Task Analysis (HTA). HTA is a means by which a task can be broken down successively into different levels of detail, which develops a detailed understanding of the task – bridging between work-as-imagined and work-as-done. The SHERPA software provides a graphical representation in the form of an analysis tree, of the HTA, as well as a tabulated version below, which can be outputted into a Word document. The overall objective is set at the top of the analysis tree, with sub-goals which must be carried out to complete the overall objective, shown beneath. Dr Embrey explains that the analysis would begin with a review of the procedures, to provide a rough idea of the structure of the task, and this would be followed by a meeting with a team of operators to evaluate in more detail exactly how the task would be carried out, and by whom. The second part of the video demonstrates how the SHERPA software can be used, once the HTA is complete, to carry out a Risk Analysis. Dr Embrey demonstrates how by working on the table below the analysis tree, warnings can be added to safety critical parts of the task, which will be carried over into the procedure. The user can work through the analysis and provide various levels of detail depending on the criticality of the various steps being analysed. By selecting the ‘Risk Assessment’ tab on the Table, the software can be used to analyse the kinds of failure which might occur at various steps; for example, failing to check that the equipment has an earthing connection prior to starting work on the generator. The user then populates the table to describe the errors and consequences resulting from these errors, the performance influencing factors, and the risk reduction measures. Finally, Dr Embrey demonstrates how to use the software to create a procedure based on the risk analysis. It has the same structure as the task analysis, and the various warnings which were put in the analysis. This procedure can also be put towards the training and competency documentation.
