Evaluate. Several human factors techniques are
available to help evaluate the potential for people to commit errors when using
a device. Analytic techniques, such as the Usability
& Safety Bench Test, identify gaps between the cognitive, perceptual,
and motor skills required to use a device safely across different use environments,
and the cognitive, perceptual, and motor skills of the target user population.
Empirical techniques, such as Usability Testing,
can identify sources of confusion, ambiguity, and inefficiency that contribute
to use errors. Still other techniques (e.g., Healthcare
Failure Modes and Effect Analysis or HFMEA) can be strengthened by adding
human factors expertise to the evaluation process. |
