# Wizard of Oz prototype
|Motive||Test functionalities before they exist|
|Participants||Design Thinking team, Users|
|Duration||From 1 hour to 1 day|
# What is it about?
Wizard of Oz prototypes allow you to test functionalities that have not yet been implemented. The user only tests a simulation of the actual functionality. Instead of the real functionality, the "Wizard of Oz" pulls the strings in the background.
# The goal
The aim of the method is to save time and money and instead to first proof, which functionalities are necessary.
# How to do it?
- Determine which functionality should be tested.
- Consider how you can realistically simulate this functionality.
- You can combine different tools such as tablets, email systems and PowerPoint with human intervention.
- Run the tests and observe the behavior of the users carefully.
# When do you need it?
Wizard of Oz prototypes are often used for the simulation of digital systems.
- various (digital) tools for the creation of the prototype
# Keep in mind
Testing with the Wizard of Oz prototypes is more useful, when the test situation feels natural to the test user.
