Benefits of Usability

Hiring a usability practioner will ensure that your site will have increased sales and revenue. If a consumer is unable to find a product on your site, then they will just go somewhere else.

In addition, you will have reduced development time and costs as well as decreased training and support costs. Simple sites require less coding for the developers and less "thinking" work on the part of the user.
