Call center Excel functions

CC-Excel installs nine functions into Excel for call center staffing and performance analysis:

Function nameDescription
CCXLAgents()Estimates the number of agents you need to handle incoming calls within specified service level parameters.
CCXLCalls()Estimates the number of calls that your inbound call center can handle within specified service level targets.
CCXLDuration()Estimates the average length call that your call center can handle.
CCXLASA()Estimates the average speed in which your center’s calls will be answered.
CCXLQueue()Estimates the average number of your inbound calls that will be queued and waiting for presentation to an agent.
CCXLOccupancy()Estimates the percentage of their time that your call center’s agents will be busy handling inbound calls.
CCXLAllBusy()Estimates the percentage of calls that will arrive while all your agents are occupied, and will therefore enter a queue.
CCXLService()Estimates the percentage of calls that will be answered within a specified service time.
CCXLLines()Estimates the number of telephone lines that are required to handle the inbound calls into your call center.

Building your own worksheets

CC-Excel’s strength is the flexibility and freedom it gives you to design workbooks that meet your exact requirements, rather than being tied to the formats and assumptions of Windows workforce management applications. With some knowledge of Excel, you can use its more advanced features such as lookup tables, conditional formatting and charting to build complex modelling tools.
