Each application that is part of the Information System has its own specifications, in addition to the common specifications managed at the information system level itself: the Application list allows you to switch between the specifications of each application.
For example, a dispute tracking and resolution system can be divided into two distinct applications: a back office used for managing and tracking disputes, and a mobile application to allow users to declare and track disputes from their phones.
The back office and the mobile application are two different Applications related to the same Information System.
