The product backlog (or "backlog") is the requirements for a system, expressed as a prioritized list of product backlog Items. These included both functional and non-functional customer requirements, as well as technical team-generated requirements. While there are multiple inputs to the product backlog, it is the sole responsibility of the product owner to prioritize the product backlog.
During a Sprint planning meeting, backlog items are moved from the product backlog into a sprint, based on the product owner's priorities.

|Product Backlog Item Effort||
Some Scrum practitioners estimate the effort of product backlog items in ideal engineering days, but many people prefer less concrete-sounding backlog effort estimation units. Alternative units might include story points, function points, or "t-shirt sizes" (1 for small, 2 for medium, etc.). The advantage of vaguer units is they're explicit about the distinction that product backlog item effort estimates are not estimates of duration. Also, estimates at this level are rough guesses that should never be confused with actual working hours.
Note that sprint tasks are distinct from product backlog items and task effort remaining is always estimated in hours.
