Web Design Evaluating Web Sites

Usability

The idea is that, no matter what you're doing, there's a user-centered way of doing it.

Users should be considered throughout the Web site design process. Usability should not be an afterthought. Testing and fixing a Web site after it has been built is inefficient and unlikely to produce good results. The best approach to take is to incorporate a model of pervasive usability into your design and production process.

The benefits of planning usability into your project are:

  • Increased end-user satisfaction
  • Increased end-user productivity, success, and completion
  • Reduced long-term development costs (costs incurred from fixing poorly designed products)
  • Reduced training and support costs
  • Return business to improve your competitiveness
