I am not aware of such a thing. However, we have quite a few clients (all internal Service Desks and IT support teams) that use Net Promoter and I thought you might be interested in a couple of things we've learned from them (even if I can't help you with your original question!):
around 15-20% response rate. Thanks!
I would like to introduce Net Promoter into our IT Service Desk. So far everyone is on board except for one thing. I can not find a benchmark for internal Service Desks. Does anyone have a standard for internal service desk benchmarks or know of where I can find one?
