Grid-lined sketchbook? Check. Whiteboard markers? Check? There is no better way to get a multi-disciplinary team on the same page faster than sketching wireframes. Quick, dirty and easily trashed or changed, sketched wireframes are the beginning of the process. They’re not sexy, but they are incredibly important. These sketches are then used as a basis for further refinement in Balsamiq, AxureRP, OmniGraffle, or straight to visual design.
