Compare Kanban and Scrum methodologies.

Scrum: fixed sprints, defined roles (PO, SM, Team), ceremonies (planning, standup, review, retro), commitment to sprint backlog. Kanban: continuous flow, no fixed iterations, limit work-in-progress (WIP), pull-based, focus on cycle time. Scrum suits: teams needing structure, predictable delivery cycles. Kanban suits: support/ops teams, variable workloads, continuous delivery. Many teams use Scrumban hybrid. Both emphasize: visualization, limiting WIP, continuous improvement. Choose based on work nature and team maturity.
