Within Analytics report suite and tool permission lists located in Admin Console, there are often duplicate (or what appear to be duplicate) names making it difficult for admin users to identify which group(s) users should be granted access to. A couple examples of this would be "DataWarehouse"/"Custom DataWarehouse" and each of the 6 "Web Services" options. While documentation appears to exist defining each of these permissions, it would be very helpful if there was a mouse-over explanation of each within the tool itself to quickly identify needed groups and avoid confusion.
Additionally, cleaning up unused permissions may help limit confusion and potentially renaming permissions to be more self-explanatory could help as well. Posting links to the following documentation explaining each of these permissions within the UI at minimum would prove helpful as well:
