Your profile can be updated by someone with the permission Manager or has the User rights and a team responsible for the team you are a member of.
Permission levels are controlled via the Administration.
To edit a profile, go to the employee (search for an employee or go through the Organisation function in the left menu) and click the Edit Profile link under the profile image.
You can now edit the following within an employee's profile:
Add an item (assignments, competencies, employment, etc.)
Change the level of a competence
Change the synonym for a competence
Remove items that you added
If you do not have permission to change the profile, you can still look at a colleague's profile.
As always, relevant competencies and skills are selected when creating or editing a resume.
