• PRODUCT Backlog: It is a list of all requirements from CLIENTS or stakeholders that are needed in the product and should be accomplished before the end of the project. 
• Sprint Backlog: It is a list of all finalized user stories, bug fixes, work items, etc., that are completed and selected by scrum to be completed during the current sprint. 
• Product Increment: It is the VERSION of the end product derived from the completion of each Sprint.
