Service Levels Are Not An Indication Of A Level Of Service.
For as long as anyone can remember, call centres have measured themselves through service levels. This mathematical formula of the percentage of calls answered within a certain time frame has been the bedrock of the industry. It has been widely accepted that by managing service levels you are ensuring a consistent and acceptable customer experience, while appropriately managing your resources. This traditional view of service levels, however, is a fallacy.
There are three main reasons why I hold this view:
1. Service levels manage to averages and not deviations to the average.
2. “Buying back” service levels are a common occurrence in the industry.
3. By not including IVR (Interactive Voice Response) time, service levels do not correctly reflect the customer experience.
No one manages to a service level target for each and every call. By the nature of the calculation, that would be impossible. Instead, we manage to service levels within a given period of time (a day, a week, a month). By stretching out our time horizon, we in affect hide wide swings in service levels that we experience all the time. By not factoring in a measurement that accounts for these deviations, we are not accounting for the consistency of service being experienced by our customers.
The problem of deviations to a standard service level is only heightened by the fact that many in the industry regularly “buy back” service levels. This is accomplished by running at service levels well above target to make up for intervals where the target was missed. This practice does not change the experience of those who waited a longer period to be answered, and is not appreciated by those who are answered faster in exchange. This practice only costs a firm additional money to meet an artificial in-house target.
Finally, service levels do not include IVR time. The IVR and the time taken to navigate it, is as much part of the customer experience as is the hold time to be answered after getting through the IVR. We are as responsible for the experience on the IVR as we are for the experience with an agent. We also have as much, if not more control over the IVR experience as we do over the agent experience.
It is essential that as an industry we challenge ourselves to find new and better ways to account for the customer experience within our centers. I invite people to add their comments and help share what they have done to combat the short falls of service level measurements within their organizations.
