Purpose

Interface analysis is used to identify where, what, why, when, how, and for whom information is exchanged between solution components or across solution boundaries.

Description

An interface is a connection between two components or solutions. Most solutions require one or more interfaces to exchange information with other solution components, organizational units, or business processes.

Interface types include:

User interfaces, including human users directly interacting with the solution within the organization
People external to the solution such as stakeholders or regulators
Business processes
Data interfaces between systems
Application programming interfaces (APIs)
Any hardware devices

Interface analysis defines and clarifies the following:

Who will use the interface
What information is being exchanged through the interface, as well as the volume of the data
When information will be exchanged and how frequently
Where the information exchange will occur
Why the interface is needed
