Scrum also has the sprint planning and retrospective phases in between the sprints. Many teams also take time to do "backlog refinement" as a second-order sprint planning process. My scrum trainer said, with full conviction, "I've never seen a retrospective done well that took less than four hours." Nobody does Scrum. Everybody just does the part where you have a defined list of tasks for a sprint and burn it down until you get close enough to zero before the next sprint starts. It's called "scrum-but."
