An instance of a Roadmap represents important documentation for the Activity or Process it is related to. Often a complex Activity such as a Process can be much easier understood by providing a walkthrough with a linear thread of a typical instantiation of this Activity.

In addition to making the process practitioner understand how work in the process is being performed, a Roadmap provides additional information about how Activities and Tasks relate to each other over time. Roadmaps are also used to show how specific aspects are distributed over a whole process providing a kind of filter on the Process for this information.
