Paper Prototyping
Joel Spolsky · Apress eBooks · 2004
Years ago, the Excel team was trying to figure out if it would be a good idea to allow users to drag and drop cells using the mouse. They had a couple of interns “whip up a prototype” suitable for usability testing, using the cutting-edge Visual Basic 1.0. Building the prototype took all summer, because it had to duplicate so much of Excel’s real functionality or you couldn’t do a real usability test.
