What is the function of a wireframe in digital product development?

A wireframe serves as a crucial tool in the planning phase of digital product development by outlining the layout and structure of a digital product. It provides a basic visual guide that demonstrates where elements such as navigation, content, and interactive features will be placed on the page or screen. By focusing on functionality and user experience, wireframes allow designers and developers to visualize and discuss the design concepts without the distractions of color, graphics, or detailed content. This helps ensure that all stakeholders have a clear understanding of the proposed product layout before moving forward with more detailed design and development work.

While other options may refer to important aspects of product development, they do not align with the primary role of wireframes, which is pivotal for establishing a solid foundation for the design process.
