Hello,

I want to achieve this formula in PA but not sure how to apply it:

Total Sum of resolve time of P1 resolved incidents / Total Number of P1 resolved incidents

P1 incident 1 equals 32mins 
P1 incident 2 equals 34mins
Total 66 mins

66mins/2 equals 33mins MTTR

Can you help me?

Thanks,
Alona
