To efficiently manage licensing in an organization with a high turnover rate and multiple license types, the best approach is to create a license assignment rule in the Google Admin console based on directory attributes.
This method automates the process of assigning licenses according to the user's role and other directory attributes, ensuring that each user gets the appropriate license type without manual intervention. This approach is scalable and minimizes the administrative overhead associated with frequent changes in user roles and turnover.
