To help explain the Requirements workflow, we have organized the activities and artifacts into workflow details as shown above.

Each workflow detail represents a key skill that should be applied to perform effective requirements management. Analyze the Problem and Understand Stakeholder Needs are focused on in the Inception phase of a project, while the emphasis is on Define the System and Refine the System Definition during the Elaboration phase. Manage the Scope of the System and Manage Changing Requirements are done continuously during the project.

The workflow details are shown in a logical sequential order, but they are, as indicated in the text above, applied continuously in varied order as needed throughout the project. Here they are shown in the sequence you would most likely apply to the first iteration of a new project.
