Mockups are visual representations of a product or design, often used in fields like graphic design, web development, and product design. They help designers and clients visualize how the final product will look and function before it is built. Mockups can be created using various tools and can range from simple sketches to detailed digital images. These representations serve as a crucial step in the design process, allowing for feedback and adjustments. By presenting a mockup, designers can communicate their ideas more effectively and ensure that all stakeholders have a clear understanding of the project’s direction.
