Sketching out, either via paper/whiteboard or with design tools such as Sketch or Axure, the basic layouts and anticipated content for the product. Wireframes should always be based on sound research and information architecture activities.
Example
This example is from a set of wireframes (done in Axure) for the Renewable Energy Group website redesign. The wireframes were based on the project research conducted, as well as the roadmap scope and the project sitemap. The wireframes were interactive and included a component library that matched the anticipated content structures needed from the sitemap.
