Wizard of OzTest new features.
“Fake it till you make it”: With the help of a Wizard of Oz Prototype, users can realistically operate user interfaces and functions before they exist. While the user only “sees the UI”, it is operated in the background by a team member to simulate interaction behaviours.
- To perform the Wizard of Oz Prototyping method, at least one operator, one moderator and one test person are needed. Since the interactions that the user is supposed to test are faked, the operator should be controlling the interface in the background unnoticeably, so that the user's experience with the interface is as natural as possible.
- The moderator starts the test by explaining what the test is about to the test person. A relaxed and calm environment should be created for the user, so that he does not have the feeling that he is in an exam situation. Explain that an idea o. software is being tested, not the person testing it, and that feedback is very valuable. If the user agrees, it can be helpful to record the test in order to log the session afterwards.
- Now the tasks can be tackled, which are prepared at best in the form of a question guide. Ask to think aloud to understand his experience. Give the process enough time and ask open questions if necessary.
- If all process steps have been completed, or the user does not get any further, the moderator ends the session. After thanking the person for their enriching feedback, some follow-up questions might be asked. For example: How did you like the overall experience? What did you notice that was particularly positive or negative? What other thoughts would you like to get off their chest?
- Afterwards, the test can be evaluated and the most important findings recorded. If audio or even video of the test was recorded, it may help to note down the original statements of the user in order to verify your own findings.
