We're doing the day-to-day forecast in WFM tool, but I build an Excel model for mid term and long term forecast.
The granularity of the long term is weekly and I have based that on a workload calculation not Erlang because there isnt much use in Erlang for that granularity.
My question is how should I account for SL (variation) in the long term forecast. The FTE requirement should go up when SL does, but a WL calculation does not allow for that.
Any suggestions?
