The purpose of a Sprint is to produce a done Increment of product.

According to the Scrum Guide1, the heart of Scrum is a Sprint, a time-box of one month or less

during which a “Done”, useable, and potentially releasable product Increment is created. The

Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all

prior Increments and thoroughly verified, ensuring that all Increments work together.
