Testing

Prototypes are useless unless you test them. This is not rocket science. People like Jakob Nielsen and Steve Krug support so-called “discount usability testing,” which is cheap and fast and yields valuable insight into your design decisions. You will use this information as the basis of another iteration of sketching, prototyping and testing. Do this at least until major issues have been fixed. We all know that software projects are tight on time and budget, so to be more efficient, test early and test often.

One of the best resources for discount usability testing is a new book by Steve Krug, “Rocket Surgery Made Easy.” Pick up a copy and read it.
