Service Level Threshold Calculations

Topic Views - 10662


Hi,

I am using the below mentioned formula to calculate the Service Level. Please let me know if this is correct -

Calls Answered within Threshold / (calls offered - Abandon within Threshold)

Hi Ns2081,

Example data: Your service level target is to answer 85% of the calls in 30 seconds (I chose these numbers randomly):

Total calls answered = 1000

Total calls abandoned = 60

Total call answered within 20 seconds = 860

Total calls abandoned within 20 seconds = 20

Total calls abandoned after 20 seconds = 40

Total calls abandoned within 5 seconds = 10

Formula #1:

Service Level = {(Total calls answered within threshold +calls abandoned within threshold)/(total calls answered + total calls abandoned)} * 100%

This calculation takes all calls into consideration; however, calls that abandoned within your service level threshold count positively, meaning they help increase your service level percentage.

Example: (860+20)/(1000+60)*100% = 83%

Formula #2

Service level = (Total calls answered within threshold) / (Total calls answered)*100%

This formula ignores calls that abandon. Clearly this is NOT an accurate reflection of what is going on in the center and is not one I would recommend, nor would any other people I work with.

Example: ((860)/1000))*100% = 86%

Formula #3

Service Level = (Total calls answered within threshold) / (Total calls answered + Total calls abandoned)*100%

Here you are given “credit” for all the calls you answered within your service level threshold and all calls that abandon will affect service level negatively, regardless of when they abandon.

Example: ((860)/(1000+60)) *100%= 81%

Formula #4

Service Level = (Total calls answered within threshold) / (Total calls answered + Total calls abandoned after threshold)*100%

Here calls that abandon after the threshold affect service level negatively. Call that abandon before the threshold do not affect service level.

Example: ((860)/(1000+40))*100% = 83%

Formula #5

Service Level = {(Total calls answered within threshold +calls abandoned within a shorter amount of time than the threshold)/(total calls answered + total calls abandoned)} * 100%

This formula uses a threshold to account for "short calls." For example, if your threshold is 20 seconds, here you would say that calls that abandon before that time will count positively towards service level.

Example: ((860+10)/(1000+60))*100%= 82%

Hope the above information will help.
