This matrix presents the message exchanges between IT services and user interfaces of the Project.

The services are the services of the project or of its sub-projects.

The tasks are the tasks of the system processes or sub-processes of the packages of 'User interface group' type or their sub-packages. These packages are the packages of the project or of its sub-projects.

The intersection is checked if message instances are sent by a service instance and received by a user interface interface or the reverse.
