be designed around. First, integration should be a priority of the new system. he
system should be able to support and involve different individuals in the medical
network. Next, the system should be highly adaptable to different procedures and
applications. Finally, the network needs to be extensive. Adding new functions to
the network should be done easily and without disruption.
A total of 17 different “use cases” were developed with specific “communica-
tion patterns.” hese are instructions for common tasks that might occur regularly.
Each use case accompanies a description of how it is used, as well as a graphical
representation. Figure 14.4 illustrates the process of placing an order from a hospi-
tal. Order placement is the fourth use case and a common task utilized by medical
practitioners.
After determining the needs of the IT network, it was necessary to concentrate
on how the system would be configured. During the design process, five different
perspectives were considered. hose perspectives are given in Table 14.4, along with

Perspective-orientedModel
Functionality perspective
How well the system works when performing
processes and other activities.
Behavior perspective
The steps that the system performs when it
performs a task. This perspective shows how
different processes are linked together.
Informational perspective
This perspective controls the low of
information within the system. It provides the
data for each process.
Organizational perspective
The organizational perspective controls
which groups are involved in a process, as
well as the roles they play.
Operational perspective
This perspective controls the distribution of
packets from system to system.
