RUP SCRUM Formal Cycle is divided into four phases, however certain workflows can be performed concurrently. Each sprint is complete in the manner of a cycle A formal project plan with numerous iterations is employed. There is no end-to-end project plan. Each iteration plan is decided at the conclusion of the current iteration Prior to the commencement of the project, the scope is determined and recorded in the scope document. Scope might be changed during the project. It employs a project backlog rather than scope scrum. Artifacts include the Scope Document, the formal functional requirements package, the system architecture document, the development plan, test scripts, and so on. The only formal artifacts are operational software. Appropriate for long-term, large-scale enterprise-level projects of medium to high complexity. Recommended for fast upgrades and organization that are not time-sensitive.
