Accurate scheduling is dependent upon the forecast correctly estimating anticipated call volume and determining the number of agents required to meet service levels. How does this affect profitability? In a real life scenario, if call volume is underestimated to the extent that 100 callers out of 1,000 hang up before they speak to an agent in a sales environment where the average order is just $50, $5,000 in lost revenues will occur per day, $150,000 per month, or a staggering $1.8 million per year.
