Description: The ‘Hardening Sprint’ is a practice within the Agile framework that focuses on fixing bugs and improving product quality before its release. This type of sprint takes place at the end of a development cycle, where the team dedicates itself exclusively to identifying and resolving existing issues in the software. The idea is to ensure that the final product not only meets functional requirements but is also robust, reliable, and free of critical defects. During this sprint, tasks related to quality are prioritized, such as code refactoring, improving automated tests, and reviewing documentation. This approach allows the team to focus on product stability, which is crucial for customer satisfaction and the development team’s reputation. Additionally, the Hardening Sprint fosters a culture of quality within the team, as all members are responsible for the integrity of the product. In summary, this sprint is a valuable tool to ensure that the software not only works but is also of high quality and ready for production use.
