I'm in the process of redefining our Help Desks ABA (abandon rate) and I was wondering if there is an ITIL standard on how to calculate abandoned calls.

We have one Help Desk that is using 6 seconds for calculating abandon calls and our Help Desk is using 60 seconds.

I've heard of some Help Desks using 20 seconds.

How does someone come up with 6 seconds verses 20 seconds verses 60 seconds?

There is no standard from ITIL

6 seconds is basically 1 to 3 rings

The question for designing a Abandon call time limit


Ask your customers or certain customers ... how long you want them to wait for the automatic pick up and how long do you want them on Hold music

I think you can also differentiate between call pick up time and abandon rate.
Abandon call is a call that was not picked up and implement threshold of 6,10,16 (whatever) seconds for which the call has to wait in the queue before it counts as a valid call. (this is to avoid calls that last for 2 seconds and the users changes his/her mind).
Then you can use call pick up time to see how fast are the SD agents responding and measure it againts the customer demands again.

So the example targets would be:
Abandon rate - 5%
Call pick up time - 98% < 20s

Does it make any sense? Smile
