A mock-up is a representation of a design or layout in a ‘real-life setting’ used to showcase what the final product will look like. Mock-ups can be digital or physical; an example of a digital mock-up would be placing a chosen screen from a web design inside a laptop, a tablet and a smartphone to show what the design looks like on different screen sizes. Mock-ups are often used in graphic design, web design, product design and packaging design. A mock-up is typically created before the final design is produced, allowing designers to review and refine the design before it is implemented. Mock-ups can be used to test different design options, evaluate user experience and usability, and communicate design concepts to clients and stakeholders. They can also be used to present designs to potential customers, investors, or partners, to solicit feedback and generate interest in the product or service.
