There are nine core workflows in the process. They represent activities and logical groupings of workers based on areas of focus. The core process workflows are divided into six core engineering workflows and three supporting workflows.

These are the core engineering workflows:

• Business modeling / planning workflow
• Requirements workflow
• Analysis and design workflow
• Implementation workflow
• Test workflow
• Deployment workflow

These are the supporting workflows:

• Project management workflow

• Configuration and change management workflow

• Environment workflow.

Although the names of these workflows may bring to mind the sequential phases of a traditional waterfall approach to development. They are actually quite different because of the nature of the iterative process and the fact that these workflows are revisited again and again through the lifecycle of a project.

There are four (4) phases: Inception, Elaboration, Construction, and Transition phase

The diagram above shows how information flows through the project, via the artifacts; the arrows show how changes in one artifact ripple through other artifacts along the arrows. For clarity, many artifacts are omitted (e.g. the many artifacts in the design model are omitted, being represented by the Artifact: Design Model).
