Not sure if this has been asked before, so apologise if it has, but our Management Team have asked for reports showing the number of calls closed compared to our SLA's.
For example, calls closed within 1 hour (of being opened), 4 hours, 8 hours - we have looked at the reports available and they all seem to show averages of calls closed. The report suggested to us to use 'Created/Resolved Trend' shows the number of calls closed at a certain hour of the day, but not how long each call took to close.
Some more detailed reports or ability to write custom reports would be really useful.
