A wireframe is a visual representation of the requirements for a project. It may be a flow-diagram of a sitemap, or how information will be processed through a website. It may also be a high-level mock-up of how the proposed website might look. Wireframes don’t include color-schemes and graphics. Think of it as someone sketching out a rough draft on paper.
Wireframes are great ways for clients to understand and approve work to be done…especially with more complex projects that may include online forms.
