To assign a new goal to someone else, go to the 'Goal' page and select 'Create Goal'. While creating a new goal, assign a new goal to specific team members by searching for their names in the 'Owners' section.
You can select multiple owners for a specific goal and click on 'Save and Create'.
If you want to assign an existing goal to someone, again go to 'Goals' pages and open the goal you want to add an owner for. Click on the 'Edit' option above the goal and select owners.
Lastly, save and update the goal.
