Helpdesk Analytics

Posted by on . No comments.

I love the Gap chart that Aaron Paxson made and I think it is a perfect visual representation of what is going on with his helpdesk tickets. The problem:  The Network Operations Team (desktop, server, communications, etc) is consistently not able to keep up on demands.  Identify the demands, the why’s, and determine a fix. So, [...]
