Looks like you need a pivot table view of your data. See if this helps https://support.office.com/en-us/art...0-0a48c1aa6752
If not, or if you really need a report, a combination of Totals queries may work. Perhaps you could combine Dept and Severity data, then use additional Totals queries for the other groupings, placing them in sub reports that you position side by side. The subs would be likely also be grouped by dept, but dept data doesn't have to appear in the subs.
The more we hear silence, the more we begin to think about our value in this universe.
