“The rule of thumb in many usability-aware organizations is that the cost-benefit ratio for usability is $1:$10-$100. Once a system is in development, correcting a problem costs 10 times as much as fixing the same problem in design. If the system has been released, it costs 100 times as much relative to fixing in design.” (Gilb, 1988)

“You can increase sales on your site as much as 225% by providing sufficient product information to your customers at the right time. In our recent research, we found that the design of product lists directly affected sales. On sites that did not require shoppers to bounce back-and-forth between the list and individual product pages, visitors added more products to their shopping cart and had a more positive opinion of the site. By understanding your customer expectations and needs, and designing your product lists accordingly, you can significantly increase your sales.” (UI Engineering, 2001)

“More than 83 percent of Internet users are likely to leave a Web site if they feel they have to make too many clicks to find what they’re looking for, according to Andersen’s latest Internet survey.” (Arthur Andersen, 2001)

“A bad design can cost a Web site 40 percent of repeat traffic. A good design can keep them coming back. A few tests can make the difference.”(Kalin, 1999)
