Mock up
A mock-up is a visual representation or model of a product, design, or concept that is used for evaluation, presentation, or testing purposes before the final product is made. The word "mock-up" is derived from the English "to mock," meaning to imitate, and that is exactly what a mock-up does: it mimics the intended final product to give an idea of how it will look or function.
The important role of Mock-ups in product development
Mock-ups are often used in various industries, such as graphic design, architecture, product development and web design. They can range from simple sketches or paper models to more detailed digital simulations. Mock-ups help designers, clients and stakeholders understand the concept, identify errors and make improvements before costly steps are taken in production or development.
