# 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?

  1. Determine which functionality should be tested.
  2. Consider how you can realistically simulate this functionality.
  3. You can combine different tools such as tablets, email systems and PowerPoint with human intervention.
  4. 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.

# Resources

  • 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.
