The importance of wireframing

Certain requirements and concepts can seem like great ideas during
initial project calls, but things can quickly fall apart when you start
laying them out on paper. Since wireframes take considerably less time
to generate than full color comps, you can spend time early on using
them to map out all of the pages for a particular site. Even at this early stage you can get a sense of the user experience and therefore spot potential usability problems with your design. Via 45royale Inc.
