A more motivated Service Desk team
Surprise! It is much more motivating to be measured on how you have helped people, rather than on how many tickets you have closed.
Measuring Service Desk personnel by how many tickets they can close per hour could lead to rushing cases/possibly not solving cases, and not delivering a great service experience to the end-user. Instead, Service Desk Personnel now have the opportunity to deliver a great experience that solve the heart of end-users' problems, be measured on and get feedback about how they have actually improved someone's day.
