Task: Derive Use-Case Functional Flow

This task describes how to merge all defined scenarios into a common workflow.

Purpose

To produce a common workflow: once a set of essential scenarios is captured, the identified functional flow is merged into a common description in an activity diagram

Main Description

The functional flow is normally an activity diagram with forks, joins and branches that represents the entire set of scenarios. Some engineers use this representation to reason about the scope of the use case and the interaction of the requirements within the use case.
