Ease of use is very broad. Some people equate the term with usability, which they consider as broad as quality itself. Here we limit ease of use to the primary characteristics that determine whether users can actually apply the information. We distinguish this ability from being able to find and understand the information.

Aspects

Task orientation
A focus on helping users do tasks that are associated with a product or tool in relation to their jobs.
Accuracy
Freedom from mistake or error; adherence to fact or truth.

Completeness

The inclusion of all necessary parts—and only those parts.
