Product Management is the owner of the Vision/Scope Approved milestone and Program Management is a key contributor. The deliverable is a Project Vision/Scope document. The milestone is achieved when the project team and customer agree on this document's content and the document is put under version control. The Vision/Scope document is a conceptual expression of the customer's requirements, presented as usage scenarios, functions, and business objects in the application's conceptual architecture. As the analysis and design activities proceed, explicit milestones to review and assess against project scope will trigger revision and reassessment of the project plan and schedule.
