Hi, I want to calculate FTE based on an ASA of 180 Seconds.
Is there a formulae for that.
The usual calculator would not answer it.
Question asked by Varun
If you want an average speed of answer of 180 seconds, then use a service level of 50% of calls answered in 180 seconds.

What will be the formuula?
With thanks to Triccia
It is the Erlang C Formula.
But the maths can get quite involved.
