Further, usability is a dependency, which requires that whatever is produced by a producer activity
must be usable for a consumer activity. An approach to manage this dependency for information output
is to develop standardization to create uniform output that is interchangeable. Examples of the output
standard forms include patient’s history, diagnosis results, and billing. In this instance, IT employment
can provide information in the form and standard as specified in advance and thus help managing
usability dependency between activities.
