You can now assign to your HRBPs (and potentially managers) a new admin role of Survey Creator. It is a perfect role for somebody who should create AND manage surveys without the other superpowers of an account administrator (such as updating employee data and seeing the results of all surveys for an account).
This way you can share admin workload, enable others to drive feedback loops within their respective sections of the organization and at the same time protect sensitive information by giving the right level of access to everyone.
You can grant and administer the Survey Creator Permission via the Account Administration > Administrators page in Culture Amp:
You can find detailed info about all admin permissions and roles here.
