Figure 2. The functional view

higher level of abstraction the global processes
are processes with no internal structure. They
are composed with other processes and they are
characterized by their goals. On the other hand the
detailed processes have an internal structure and
are composed with composed steps. A composed
step may be an activity or a sub-process. A sub-
process is a set of activities and sub-processes
from a finer grained level. An activity is a set of
Actions. An action is the finest grained functional
entity that cannot be composed any more.

Processor Role that is responsible of the execution
of activities and also delegating performer roles
assuming these activities.

the interactional View

Figure 4 depicts the interactional view which
captures interactions between elements of a
process. The elements of the process that can
interact together are called Interactive Part(s).
While interacting, these elements may exchange
resources of different types. An interaction is a
connection between two elements communicat-
ing between them. A simple interaction is used to
exchange a single resource between two interactive
parts, while a compound interaction is a set of
interactions (simple or compound). An exchanged
resource may be an item of any type. A message
flow and an artifact sequence flow are examples of
interactions in BPMN. Object flow is an example
of interaction in the Activity Diagram of UML.

the organizational View

The actors in a business process may be humans
or resources of different kinds (software, servers,
machine, etc). These actors may be names of
persons or resources or just their function in the
organizational structure of the enterprise. Model-
ing processes by using the names of actors could
lead the process to a non wished level of details
and remove the generic character of the process.
Therefore, abstract roles are assigned to the dif-
ferent actors participating in the running of the
process. Figure 3 shows the organizational view
attributing roles to External and Internal actors.
A Performer Role is responsible of some activi-
ties in the process. Every detailed process has a

the behavioral View

Figure 5 shows the behavioral view which captures
the different elements for scheduling the process in
time. It highlights the succession between different
Course Parts of the process. The course parts are:
