What is the primary purpose of a mock-up?

The primary purpose of a mock-up is to visually represent the user interface of an application. By creating a mock-up, designers and developers can showcase the layout, design elements, and navigational structure to stakeholders, including clients. This allows clients to visualize how the final product will look and feel, facilitating discussions about design choices and necessary adjustments before moving on to development.

Mock-ups serve as an important communication tool that helps ensure that everyone involved has a clear understanding of the intended user experience. By illustrating the design concept without the need for a functional prototype, mock-ups allow for early feedback and refinements, which can lead to a more successful final product.
