It has recently become popular to design new websites and innovative Internet services with the idea to throw it at the wall and see if it sticks . The assumption is that speed is everything. Well, speed is indeed important, but it is not everything.
Customer satisfaction is everything.
Launching a bad site with poor usability is a guaranteed way to waste money since it will have to be redesigned more or less immediately. If these users get a bad experience, they will not only be lost to you as customers, they will also be lost as potential future advocates for the site. In fact, any hopes of viral marketing will turn into a bad fever as infected users warn others to stay away from the site. Once a user has had a bad experience on a website, it is very difficult to convince him or her to come back. Resampling is one of the hardest sells and will cost your marketing budget much more money than the modest cost of getting the website right in the first place.
