UPEDU has two dimensions:
The first dimension represents the dynamic aspect of the process as it is
enacted, and it is expressed in terms of phases, iterations, and milestones.
The second dimension represents the static aspect of the process: how it is
described in terms of process components, activities, workflows, artifacts, and
The graph shows how the emphasis varies over time. For example, in early iterations, we spend more time on requirements, and in later iterations we spend more time on implementation.
Finally, UPEDU has a specific Case-Study derived from the Rational Unified Process 2000 along with available deliverables/artifacts.
