An Exploration of End-User Critical Incident Classification
MetadataShow full item record
This study explored end-user classification of self-reported critical incidents (usability issues) using the UAF, a technique that was hoped to reduce expert interpretation of usability problems. It also explored end-user critical incident reporting from a usability session recording, rather than reporting incidents as soon as they occur, a technique that could be used in future studies to compare effectiveness of usability methods. Results indicate that users are not good at diagnosing their own critical incidents due to the level of detail required for proper classification, although observations suggest that users were able to provide usability information that would not have been captured by an expert observer. The recording technique was successful, and is recommended for future studies to further explore differences in the kind of information that can be gathered from end-users and from experts during usability studies.
