There are times when processes and issues exist that are external to the software but implicit to the business process and are required to be available for reference and research. Users should not have to stop the task they're performing to hunt around for printed materials or information before they can get on with the task at hand. Therefore, the user documentation should provide access links directly to available reference material.
The visual metaphors for navigating through and displaying information in online knowledge documentation must be available to allow users to find what they need quickly and can also be available for specific screens or menus, so users can just click a button, image or a menu item to get more information.
