You can share the feedback with just the person, with the person and their manager, or you can use the feature for documentation purposes and choose not to share the feedback with the person. The recipient of the feedback (and their manager if you select that option) receives an email as well as a notification in Workday.
This is a great way to share feedback that you might otherwise forget when it comes time for a review, and your thoughts are documented in your colleague's file. It also gives us all a great way to share kudos now that most of us are hybrid and don't have a centralized way to share our thank-you notes.
For more detailed instructions see the Providing Feedback Quick Reference Guide.
