Overview
A Wizard of Oz (WOZ) test is an evaluative product experiment where humans manually perform tasks that you eventually plan to automate. Users experience the manual work as seamless automation, allowing you to validate product-market fit before investing in actual technology development.
Key Definition
"The WOZ test involves one or more individuals simulating fully functioning product features without the use of technology."
How It Works
- Build a prototype without automated algorithms
- Assign at least one "wizard" to manually simulate product behavior behind the scenes
- Allow users to interact with the product naturally
- Collect data on whether the solution delivers value
Time Commitment
WOZ testing requires substantial resources. Depending on task complexity and user volume, projects can span from days to several weeks. For example, image categorization requires less time than voice transcription.
What It Answers
- Which features provide the optimal solution?
Potential Biases
- Sampling bias
- Confirmation bias
Key Insight
"If you can hire five interns to fake a feature, don't bother coding it" emphasizes the efficiency advantage of testing before full automation.
