—an instance when a test participant made a mistake while performing a task.And perhaps the mistake occurred while the test participant was performing a high-risk task, thereby causing angst among the development team members because the use error imperiled a successful validation test.It takes discipline—courage even—to adopt and maintain this mindset.

An intensive analysis of use errors usually reveals user interface design flaws, missing risk-control measures that should have accounted for normal human failings and protected against related use errors.Following a high-risk , the device manufacturer must perform a root cause analysis.The cause might initially appear to be the user’s failure to do the right thing.Marriage does include a legal obligation to take care of each other, including financially, so I think the families' voice would at least be heard.If the families are these people's legal guardians, then the decision to get married must be approved by them.Meaning of symbols indicating alarms off versus audio off are not widely recognized by intended users.On-screen indication “ALARMS OFF” is not attention-getting due to its small size and location within an area of densely packed information.test participant acts forgetful, inattentive, fatigued, careless, or in another way that appears to cause an error, view the user’s behavior as normal and expected rather than the root cause of the error.For example, a test participant might forget to perform a step when setting up a device because there are 25 separate steps that must first be remembered and performed in order.It is tempting to draw such conclusions when test participants make comments such as “That mistake was totally my fault,” “I forgot to follow the instructions,” or “My bad!” Manufacturers seeking a use error’s true root cause should resist test participants’ readiness to blame themselves for mistakes.
