The simplest way to update your goals is as part of your Perform & Engage 365 check-in.
All goals assigned to you are added to the end of your check-in, with the option to share a progress update. These updates will be sent to your manager along with your check-in question responses.
As well as updating your goal progress, you are able to share comments, attach files, and archive or complete goals as required.
Note: This process is the same across web and Microsoft Teams.
