This chapter helps to determine the compliance of the exchanges defined within functional processes and the exchanges received and/or sent by these functional processes. The chapter lists all the exchanges modeled within and outside each functional process between the contained and detailing activities.

Different icons with arrows are used to give valid information relating to each message and interaction. These arrows help to determine what is missing from and what is unnecessary for the exchange design.

The information of the chapter is presented in table form with a list of the operational activities of the architecture. For each operational activity the balance between the incoming and outgoing information is shown.
