Abstract:

Embedded user assistance is only part of a complete documentation plan. It does not replace the need for other types of content. For example, embedded user assistance is not a good delivery mechanism for comprehensive concepts and detailed discussions of a topic with strategy and best practice guidelines. However, with a strong design, embedded user assistance can support the immediate needs of the user and provide a valuable, contextual link that steers the user into the other parts of the documentation as needed.
