A wireframe is a two-dimensional outline of a website or app and thereby provides a clear overview of the layout, user flow and structure. Wireframes can be drawn by hand or created digitally, depending on how much detail is required. The wireframing process tends to take place during the exploratory phase of the product life cycle. During this phase, the designers are testing the scope of the product, collaborating on ideas, and identifying business requirements. A wireframe is usually the initial iteration of a webpage, used as a jumping-off point for the product’s design.
