Usually a Sprint Goal is a short (one- or two-sentence) description of the _objectives of the sprint_ , the _higher purpose (vision) of why it is worthwhile undertaking the sprint_.
Please, note that a team might reach the Sprint Goal even if they can’t finish all stories.
**A Sprint Goal is usually the delivery of a feature (“ _one coherent function_ ”). Anyway, The Scrum Guide underlines that the Sprint Goal can be “ _any other coherence_ ” that allows the Development Team to stay focused and “ _work together rather than on separate initiatives._ ” For example the team and the Product Owner can agree to use the sprint to address a risk ( _Does the architecture provide the desired performance?_ ) instead of creating a product increment.**
