Is there a service level calculator for multiple days that is used for back office and not calls.
Or does anyone know the calculation for this?
Question asked by Kathryn
I am not aware of one. What sort of work are you looking to calculate and what sort of service level are you trying to create?

I am trying to work out the number of items processed with a service level period of 48hrs / 5 days.
I have been tasked with projecting service level for an anticipated volume of work, the work in question has a 5 day service level attached were we must log all items within this time frame. However we are anticipating a back log of work items, therefore, I am looking for a calculation that can project service level including back logged items, for the items processed after 5 days.

OK. So what are the inputs and outputs that you are trying to obtain.
I guess that you have
For outputs you are trying to work out percentage of tasks completed within 48 hours?
Is this correct?
With thanks to Jonty
Yes that is correct.
I have been tasked with projecting service level throughout a training period running from Feb 17 to June 17.
I have the number of staff available throughout, the forecast volume of work, expected work output, and have been asked to ‘project’ the SLA in this period. I am happy doing this for 24hrs, however, when the team has a 48hr SLA, I cannot work out how to calculate the SLA based on the work in / out. For example:
_________________________________________
Date: 6/02 7/02 8/02 9/02
Staff: 5 5 6 5
Work in: 100 120 90 100
Work out: 100 100 120 90
SLA: XX XX XX XX

You don’t have enough information there to calculate the service level. Here is the formula
Service level = [ Number of tasks completed within the service level threshold] / [Number of tasks offered] * 100
In order to work it out you would need to count the start time and end time of each task.

I also have the same problem I am trying to solve. I have a process that requires 10 Business Days SLA, how will I calculate the headcount requirement?
With thanks to Rachell
It may seem strange but the headcount is very similar between 4 hours and 10 days.
