Encourage efficient and effective human-computer interactions. Designers should make every attempt to reduce the user’s workload by taking advantage of the computer’s capabilities. Users will make the best use of Web sites when information is displayed in a directly usable format and content organization is highly intuitive. Users also benefit from task sequences that are consistent with how they typically do their work, that do not require them to remember information for more than a few seconds, that have terminology that is readily understandable, and that do not overload them with information.
Users should not be required to wait for more than a few seconds for a page to load, and while waiting, users should be supplied with appropriate feedback. Users should be easily able to print information. Designers should never ‘push’ unsolicited windows or graphics to users.
