Answer:
Super users.
Explanation:
A super user is a member of a department that has intimate knowledge of internal processes and bears responsibility of managing knowledge sharing in the department. Super users are the main source of support for end-users of a new product.
Super users assist end users with any issues, help them gain familiarity with the new software, and give feedback to the vendor on any issue.
Vendors also grant super users administration rights so they can resolve some problems independently.
