I am new to the Scrum framework and I’m getting confused between the two types of backlogs. Who owns which one, and how often do they change? I want to make sure I’m following the Scrum Guide correctly as we set up our first project. Any simple explanation would be really helpful!

Think of the Product Backlog as a "to-do" list for the entire product's life; it is dynamic and owned by the Product Owner. It contains every feature, bug fix, and requirement. The Sprint Backlog, however, is a subset of those items that the team commits to finishing in a specific sprint. The Developers own the Sprint Backlog. While the Product Backlog is constantly refined, the Sprint Backlog should remain relatively stable during the sprint to avoid distracting the team, although the plan for the work can be updated as more is learned during the Daily Scrum.
Do you understand how the "Definition of Ready" acts as a gatekeeper between these two different backlogs during the planning session?
The Product Backlog is about the "What" and the "Why," while the Sprint Backlog is more about the "How" and the "When" for the next two weeks.
Perfect summary, Betty. It really comes down to the long-term vision versus the short-term execution plan that the team follows.
Thomas, that's a crucial point. The Definition of Ready ensures that any item moving from the Product Backlog into the Sprint Backlog is clear and actionable. Without this gate, the Sprint Backlog becomes a mess of half-baked ideas that the team can't actually complete. It helps the Product Owner realize that their "wish list" needs to be turned into specific, measurable tasks before the team can even consider starting the work.
