Expert interviews are conducted to get a better understanding of one specific working process and how it can be organized/reorganized within the user interface. A very domain specific knowledge is needed to understand interface requirements better. Functional aspects come additionally and can not be separated from interface needs.

==Software based Evaluation==
Currently the pubman prototype is monitored by an open source application called [http://www.labsmedia.com/clickheat/index.html ClickHeat]. This solution generates pictures called heat maps. Heat maps show where users click (dots) and how often (colour).
Example:
[[Image:clickheat_depositor.png|framed|center|Heat Map of Depositor Workspace]]
Software based evaluation is not conducted for R3. Currently no open source application is available for analysing dynamic pages.

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.

Usability Interviews (Thinking Aloud)[edit]

Interface releases are tested together with potential users from institutes of the Max Planck Society. They perform tasks covering important application functionality. An interviewer tracks feedback and observes user interactions. All issues are noted down. The test result is accumulated if at least 8-11 interviews are performed. A summary is given at the end of the interview series which leads to measures and changes in the interface.

The following table shows what is needed to conduct an interview at an istitute:

Participants

1

Supervisor

1 plus 1 visitor (optionally, usually developers)

Equipment
  1. PC
  2. Internet connection
  3. Tasklist (provided by UIE)
  4. Test Form (provided by UIE)
  5. Recording Device (optionally)
Duration

1h

Results

Document with notes on user actions for each action/step.

The results are analysed after 6 - 8 interviews towards a statistic, providing GUI issues ordered by functional area and tasks.

Steps
  1. Short Introduction
  2. Participant solves task independently
  3. Open questions/diskussion


Usability interviews are conducted to discover, document and classify usability issues for

  • a specific release (e.g. PubMan 2.0.0.1)
  • a functional prototype
  • a prototype draft

Up to 8 interviews are usually sufficient to discover the main flaws of a GUI. The interviewer just provides tasks for his participant. The participant does all tasks on his own and should be encouraged to comment on his actions. It is not recommended for the interviewer to interfere in any form. If the participant gets stuck and there are important steps to follow, he gets a hint how to continue.

Interviews can be recorded optionally if participants agree. If a participant is not able to solve a task or step it will be noted as a fatal usability issue. For later interviews with a more standardized set of tasks the issues are to be classified in the following way:

  1. Fatal (Task could not be finished successfully or in a proper way)
  2. Serious (Task could not be finished on the first attempt or user performance is bad)
  3. Minor = (The user hesitates, is not sure or does not feel comfortable with the flow)

For each interview the UIE team provides an interview outcome. The document contains all tasks, observation notes and comments of participants. Additionally the interviews collect demographic characteristics as well to prepare data needed for personas. After a valid number of interviews exists they are analysed and summarized.

Interview Form Example[edit]

Submission Participant 01 Participant 02 Participant 03
