A mockup is a full-size model of a design or device, used for product presentations, testing, or other purposes. It is an effective tool for demonstrating the look, feel, and function of a product before committing to the full development process. Mockups are often used in the early stages of product design to quickly assess the viability of a concept. They are also helpful for obtaining feedback from key stakeholders, helping to refine a product before it is finalized. By using a mockup, designers can gain valuable insight into how their product will be received by customers and make changes accordingly.
