If both a heuristic evaluation and a think-aloud usability study were used, the identifiers might be HE6 or TA89.Follow the unique identifier with the word Problem, if the report pertains to a usability problem of the interface, or the words Good Feature, if it describes an aspect of the interface you feel should be preserved in any redesign."

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 image of a cluttered screen and the heuristic about aesthetics and minimalist design. Or, it could be a list of menu items that do not have keyboard shortcuts and the heuristic about providing shortcuts. 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 said. If you have video annotating or editing capability, it can be a brief animation.You need to include enough pertinent information about the identification of an aspect for the reader to understand what the analyst was thinking when the aspect was identified (for HE) or what the user was trying to do when the aspect either hindered or facilitated the user's progress."

That is, if UAR #1 related to UAR #30, then UAR #30 should point to UAR #1 in this section and UAR #1 should point to UAR #30 in its version of this section.
