Human error assessment and reduction technique HEART

Human Error Assessment and Reduction Technique (HEART) examines particular task types and their associated error probabilities using tables of task types and faaors which impact on the performance of the task. 

Human error probability assessments using the Human Error Assessment and Reduction Technique (HEART)... 

The Human Error Assessment and Reduction Technique (HEART) structures PSF considerations for the analyst who uses these to modify basic error probabilities. It assumes that human reliability is dependent on the generic nature of the task and that the level of reliability will be consistent (given a likelihood within probabilistic limits) under perfect conditions. The reliability can be varied for non-perfect conditions using Error Producing Conditions (EPCs). 

HEART Human error assessment and reduction technique. Relatively quick to apply, and understood by engineers for quantification of human errors. It is a generic one and has general use. 

Various human reliability assessment techniques may be used to evaluate the effectiveness of cross-checking activities - eg THERP (Technique for Human Error Rate Prediction) and HEART (Human Error Assessment and Reduction Technique). It is important that any assessment is made by a competent human reliability specialist and that it is based on information provided by the operators who actually carry out the filling operation. 

HEART Human error assessment and reduction technique... 

For some time there has been an interest in exploring the underlying reasons, as well as probabilities, of human error. As a result there are currently several models, each developed by separate groups of analysts working in this field. Estimation methods are described in the UKAEA document SRDA-Rll, 1995. The better known are HEART (Human Error Assessment and Reduction Technique), THERP (Technique for Human Error Rate Prediction), and TESEO (Empirical Technique to Estimate Operator Errors). 

Similarly, there many techniques to face and comhat human error such as technique for human error rate prediction (THERE), human error assessment and reduction (HEART), etc. already discussed in previous chapters. 

HEART Human Error rale Assessment and Reduction Technique Williams, 1988... 

HEART is an error quantification process that is quick to use. The process defines a set of generic error probabilities for the types of tasks being examined and identifies the error-producing conditions associated with them. For each of the error-producing conditions the human error probability is multiplied by the error-producing condition multiplier. The tool also provides some guidance on approaches towards error reduction. A human performance model-based technique utilising some standard probabilities. Data-based method to assess and reduce human error and improve operational performance.
