. Wizard of Oz prototyping (WOZ prototyping) is a design methodology used in to improve the user experience. WOZ prototyping requires developers to create a rudimentary model of the completed product, which is called a. The prototype may be quite simple, using every-day objects to represent parts of the finished product or it may be a working model, capable of performing some – but not all – of the tasks the completed product will perform.
Once the prototype has been created, developers use to test how end users will interact with the product. The WOZ methodology requires three things: a script that provides directions for what is to take place, a person to play the role of the end user and a human “wizard” that will perform tasks that will simulates the behavior of the completed product. The person playing the end user may - or may not know - that they are playing a role or that the wizard’s tasks are being performed manually by a human being instead of by a machine or computer program. Wizard of Oz prototyping is often used in and to improve how are implemented in software. After each, anecdotal feedback and data is gathered and analyzed to help improve the next round of development. The test-and-learn cycle is repeated until development is concluded.
The term Wizard of Oz protoyyping is credited to usability expert Dr. Jeff Kelley, who was inspired by the scene in the movie The Wizard of Oz in which Toto the dog pulls back a curtain to reveal that the is actually a man who is flipping switches and pulling levers.
Generally, wizards use diverse tools to 'walk' human users through a process. Many of these wizards are composed of specific forms in object-oriented programming languages that frame the tutorial itself. Through this graphical user interface, the wizard might use menus, drop-down lists, checkboxes, command buttons and other tools to automate or guide some sort of process.
EXE ('executable') files, such as softinfo.exe, are files that contain step-by-step instructions that a computer follows to carry out a function. When you 'double-click' an EXE file, your computer automatically executes these instructions designed by a software developer (eg. Informer Technologies, Inc.) to run a program (eg.

For example, a wizard is often included in software drivers for setup instructions. From an initial wizard screen, a user can click on a 'next' button to advance to the next step in the process, while reading the text and manipulating the controls on each successive screen, to make sure that every step of the process happens properly. These wizards also incorporate user-passive tools, for instance, 'wait' screens that show clearly how much time must elapse while the computer undertakes an installation step or other task on its own.
