im using the following formula to compute for the staffing requirement on a 30min interval:
volume/(30mins/AHT)/.80 - - > Efficiency or utilization
But for the daily requirement, i use this formula:
Base Staff=volume * AHT / shift (7.5hrs) * efficiency of .8
or volume/(Response time - Increment or length of shift)/AHT/Efficiency
Please advise if Im doing it right? Also, how do I compute for the weekly requirement if I have a 15-16K volume with an 85% in 24 hrs TSF or response time, with a 10-12mins of AHT? Is it safe to compute based on man hours let's say, I get the max staffing per interval of the day and multiplied it by 7-8 hours and multiply it by 5 and divided it by 40hrs?
Hope you can help me on this as I have report for tomorrow :( thanks a lot!
