What is the true purpose of a Sprint in Scrum?

The true purpose of a Sprint in Scrum is to produce a done increment of working product. Each Sprint is a time-boxed iteration, typically lasting between one to four weeks, where the Scrum Team focuses on delivering a potentially shippable product increment that meets the Definition of Done. This increment is built based on the items selected from the Product Backlog during Sprint Planning.

The process emphasizes collaboration, adaptability, and continuous improvement, allowing teams to refine their efforts and ensure they are advancing towards the overall product vision. By delivering a working increment at the end of each Sprint, teams can obtain feedback, assess progress, and make informed adjustments in subsequent Sprints, ultimately enhancing the value delivered to stakeholders.

The other options relate to aspects of product development and process management but do not capture the core purpose of a Sprint, which is primarily centered around delivering a usable output rather than brainstorming ideas, reviewing efficiency, or finalizing backlog items.
