Mockup


In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup is a prototype if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer.

Mockups are used as design tools virtually everywhere a new product is designed.

Mockups are used in the automotive device industry as part of the product development process, where dimensions, overall impression, and shapes are tested in a wind tunnel experiment. They can also be used to test consumer reaction.

Mockups, wireframes and prototypes are not so cleanly distinguished in software and systems engineering, where mockups are a way of designing user interfaces on paper or in computer images. A software mockup will thus look like the real thing, but will not do useful work beyond what the user sees. A software prototype, on the other hand, will look and work just like the real thing. In many cases it is best to design or prototype the user interface before source code is written or hardware is built, to avoid having to go back and make expensive changes.

Early layouts of a World Wide Web site or pages are often called mockups. A large selection of proprietary or open-source software tools are available for this purpose.

Mockups are an integral part of the military acquisition process. Mockups are often used to test human factors and aerodynamics, for example. In this context, mockups include wire-frame models. They can also be used for public display and demonstration purposes prior to the development of a prototype, as with the case of the Lockheed Martin F-35 Lightning II mock-up aircraft.
