User Interface Evaluation
|
Interfaces, built at the MPDL are subject to evaluation. Main focus are all interfaces of the current PubMan solution. Evaluation of the User Interface Engineering team has different approaches: Usability Interviews and tests, GUI Workshops and software based evaluation.

Up to 8 interviews are usually sufficient to discover the main GUI flaws. The interviewer just provides tasks for his participant. The participant does all tasks by his own and should be encouraged to comment on his actions. The interviewer is not recommended to interfere in any form. If the participant gets stacked and there are important steps to follow, he gets a hint how to continue.
If a participant is not able to solve a task or step it will be noted as a fatal usability issue. For later analysis flaws are classified in the following way:
- Fatal (Task could not be finished successfully or in a proper way)
- Serious (Task could not be finished on the first attempt or user performance is bad)
- Minor = (The user hesitates, is not sure or does not feel comfortable with the working flow)
- Cosmetics = (No influence on user performance)
