Systematic Human Error Reduction and Prediction Approach (SHERPA)

The systematic human error reduction and prediction approach (SHERPA) was developed by Embrey (1986) as a human-error prediction technique that also analyzes tasks and identifies potential solutions to errors in a structured manner. The technique is based upon a taxonomy of human error, and in its original form it specified the psychological mechanism implicated in the error. The method is subject to ongoing development, which includes the removal of this reference to the underlying psychological mechanism.
