The group division was created by our contact person of the organization that you are completing the questionnaire for. If you have any questions about the group division or which group you have been placed in, you can contact your manager to ask who is coordinating the survey in the organization.
It could also be that your organization has opted for the possibility of appointing managers as local coordinators and having them create surveys themselves. Then you will see the survey's name, not a group, stated in your invitation. This name was created by the local coordinator who created the survey. If it is not clear for what purpose and for which team you have to fill in the questionnaire, contact your manager or your HR contact person.
