![]() You then have a designated “wizard” behind the scenes who controls the responses sent to the user. It makes it possible to test a concept or design by having a moderator lead a face-to-face session with each user. The Wizard of Oz methodology is an easy way to test a user’s interaction with a website or app. You can determine which are necessary and which are not by faking the functionality you want to test with your users. ![]() WoZ prototyping aims to reduce the amount of time and money by testing functionalities not yet implemented. Testing new websites, redesigns, or apps can be a time-consuming process, and often costly. You can learn more about UX, UI, and usability. The aim is to improve the user experience (UX) and can be helpful for user interface (UI) design and usability. WoZ prototyping is often used in rapid development - the quick creation of a full-scale model. Once you know the important functions, you can then refine them through more in-depth user testing. ![]() Just like the wizard pulling the strings behind the curtain in The Wizard of Oz, a design team can fake features so that the user thinks that the responses are computer-driven when they are actually human-controlled so they’re testing a simulation of the functionality. Essentially, and for our purposes, a prototype is an early model or release of a website or app built to test a concept, process, or function. To understand the concept of Wizard of Oz (WoZ) prototyping, let’s first talk about what we mean by a prototype.
