I haven’t reviewed it and I don’t know what Nielsen Norman Group (NN/g) usability guidelines were used or how they were derived. But here it is, “LIFT-Nielsen Norman Group Edition,” a new software product that allows developers to check pages for compliance with usability guidelines as they code. It works with Macromedia Dreamweaver (4.0 or MX) on both Windows and Macintosh. LIFT NN/g checks to ensure that websites are compliant with the World Wide Web Consortium’s accessibility guidelines and Section 508 guidelines. It’s Jakob Nielsen in a box!
