10.6 Use of Human Reliability Analysis Techniques for Analyzing Procedures
HRA techniques should be reserved for the most critical procedures. For instance, HRA should not be used for analyzing simple maintenance procedures because of the cost of performing the analysis. However, for critical operations, it is appropriate. Determining where recovery actions, such as inspection steps, should be in procedures is the best use of HRA techniques.
