Make the name as short as sible (about three to five words) but still descriptive and distinguishable from other aspects of the system. If this UAR is about a problem (as op ed to a good feature), make sure you have a name t describes th

7、e problem, rather n a solution.;s3=This is the objective supporting material t justifies your identifying the aspe worthy of report. This section needs to contain enough information for a reader of this UAR to understand what triggered the report. For an HE report, for instance, this could be an ima

In a think-aloud study this is usually what was on the screen (a screen shot or description), what the user did (keystrokes, mouse movements), what the system did in response to any user actions, and what the user sai

This includes how frequently the users will experience this aspect, whether they are likely to learn how it works, whether it will affect new users, casual users, experi

It is not nesary to have a solution as soon as you identify a problem-you might find after yzing the wholeerface t many problems are related and c

However, if you do proe asible solution, report anypotential design trade-offst you see;s7=It is often the case t UARs are related to each other. This is where you record which UARs this one is related to and a s ement a
