Analytical intervals

Print this Topic Previous pageReturn to chapter overviewNext page

All CC-Excel functions make reference to the number of calls that a call centre handle, either as an argument or as a result. The functions assume that these values relate to the number of calls handled in a sixty minute period. In some cases, call volumes for only thirty minutes are available. Before these are applied as an argument to a CC-Excel function, these numbers must be doubled to convert them to hourly figures.


For example, consider the following use of the CCXLAgents() function:


=CCXLAgents( B2 , 180 , 80 , 20 )


which would be used to estimate the number of agents required such that 80% of calls were answered within 20 seconds. The function assumes that the number of calls specified in cell B2 relates to a period of one hour. If cell B2 contained a thirty minute call volume, then the value should be double, like this:


=CCXLAgents( B2 * 2 , 180 , 80 , 20 )


The CCXLCalls() function returns an estimate of the number of calls that an inbound call centre can handle in one hour. If a figure for thirty minutes is required, then the function result should be halved.


Similarly, if fifteen minute analytical intervals are to be used, function arguments should be multiplied by four and function results should be divided by four.
