How to create these 2 Indicators for Performance Analytics? Average time and Average age

[AbdurRahmanSnow]

Good morning.!
I have requirement to create 2 indicators for Performance Analytics? We already have average time to resolution in our Dashboard/Report. We also want the below.

Requirement:
- Average time tickets stay unassigned as they enter my group. (before someone assigns to someone)
- Average age of open ticket ("how long has this ticket stayed open for?") i.e. days / hours / months

Please help.

Hi @AndersBGS . Good evening.!
Thank you for the valuable reply. But I think, your solution is more towards "

Average RESOLUTION time", instead of "Average age of open tickets"?

Can you please guide me, if I am confusing?
I have 2 different scenarios:
- Average time tickets stay unassigned as they enter my group. (before someone assigns to someone)
- Average age of open ticket ("how long has this ticket stayed open for?") i.e. days / hours / months

Hi @AbdurRahmanSnow 

Yes, you're absolutely right - if you're looking for the average age, then you need a PA script as you don't have a defined end time other than open till "current time"
