Abstract:

There are several usability-related issues, methods, and procedures that require careful consideration when designing and developing Web sites. The most important of these are presented in this chapter, including 'up-front' issues such as setting clear and concise goals for a Web site, determining a correct and exhaustive set of user requirements, ensuring that the Web site meets user's expectations, setting usability goals, and providing useful content.
