Human error assessment and reduction technique

Bring to the process a large amount of experience to human factors effects from different industries. The key elements of HEART are a listing of a number of tasks in tabular form along with an associated mean HEP and a range of values to cover uncertainties in the estimates. The method also covers a number of weighting factors, which are introduced to cover the potential influence of a range of PSFs.
Although the central part of the method is task oriented, the task was defined as something more global rather than the subtask approach taken by Swain and Guttman.
