A Model of the Rational Unified Process

A process describes who is doing what, how , and when . The Rational Unified Process is represented using five primary elements:

• Roles: the who

• Activities: the how

• Artifacts: the what

• Workflows: the when

• Disciplines: the "container" for the preceding four kinds of element

The first three elements are shown in Figure 3-1, and Figure 3-6 shows a workflow.
