The changes you can make depend on what stage the review is at and what settings are configured in your account.
If you’ve submitted your comments and ratings already and wish to make changes, the review will need to be rewound to the correct stage to allow you to do this.
You are able to see what stage your self assessment is at, as well as who is expected to make comments and ratings at which point in the cycle.
Simply do this by hovering over the dots at the top of your review, here you can see a standard 3 stage workflow:
Note: As an employee you will need to ask your manager to rewind the review to Stage 1.
Once you’ve made your changes
If you're just modifying comments and ratings that you've already submitted, your changes will be immediately visible to others who can see the review report.
Any new comments or ratings will need to re-submitted using the Share and progress button before others can see them.
