I believe that the Task Analysis and the Use Error analysis is a good way to asses product design risks. Older models tend to neglect the psychological aspects of the individual user. Also, traditional human factors methods only detect errors that just happen to occur during testing with no real systematic way of identifying or assessing use error. The Task Analysis and the Use Error analysis both prioritize the errors. After a rating session, inter-rater reliability is measured to ensure that it is reliable and trustworthy to use to analyze the assessment. TA-UEA can also be used in conjunction with FMECA to address use issues. This method moves risk management beyond treating the user as a causal agent of system failure and places a large focus on the process being analyzed. This usually helps in the risk analysis stage and is the most effective way to develop a successful product.
