Sprint backlog – The Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal. The Sprint Backlog is a forecast by the Development Team about what functionality will be in the next Increment and the work needed to deliver that functionality into a “Done” Increment.
Product backlog – The Product Backlog is an ordered list of everything that might be needed in the product and is the single source of requirements for any changes to be made to the product. The Product Owner is responsible for the Product Backlog, including its content, availability, and ordering.
Velocity chart- A velocity chart shows the sum of estimates of the work delivered across all iterations. Typically, velocity will stabilize through the life of a project unless the project team make-up varies widely or the length of the iteration changes.
Burn-down chart – It is a chart that shows how quickly you and your team are burning through your customer’s user stories. It shows the total effort against the amount of work we deliver on each iteration.
