– Scope is predefined ahead of the venture start and documented inside the scope document. During the undertaking, scope may be revised.    – It uses a assignment backlog in region of scope scrum

– Artifacts embody Scope Document, formal useful necessities bundle, gadget shape record, development plan, check scripts, and so on.    – Operational software is the best formal artifacts
