In my Deskpro set up I have 5 different departments. Each department needs to be separated from the other. HR has nothing to do with IT, so there is no need for those two departments to share SLAs. SLAs should be department specific. HR has nothing to do with IT, so there is no need for those two departments to share labels. Labels should be department specific. Working hours also need to be department specific and multi regional. We have offices in different time zones, but within the same department. You've done wonderfully separating departments in other ways throughout the system, but there are still some obvious holes, until fixed, we cannot utilize those features of the helpdesk system. Every feature you add needs to have departmental separation in mind. It should be a standard component. Thanks for reading.
