How the Forecast System Generates Data
Call Volume/Agents Forecast Reports
No Trending (Weighted Average of Data):
1. Find the Weighted Average of Calls Carried (WACC) for the current
data.
a. Multiply the Number of Calls Carried (NCC) in each intrahour
interval for historical days C1 through C4 by the assigned data
weights.
b. Add the weighted data together, and divide that sum by the
sum of the individual weights.
The equation for WACC is as follows:
W xNCC
1 C 1
WACC
= ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- -
where W
1
2. Divide the Change Factor (CF) by 100. For example, if the CF were
100, this step would produce a value of 1.
3. Multiply the factors found in the previous two steps to get the FCC
for each intrahour interval.
FCC
= WACC
