“It is 6-7 times more expensive to gain a new customer than retain an existing one.” – Yankee Group“2/3 of customers leave a vendor because of inadequate customer care.” – Yankee Group
Good customer care means the following:
Erlang C
Erlang C is a formula linking the average waiting times to the number of callcenter agents, and call volume, and the ABC of a callcenter supervisor. It says that with the same voice traffic per agent (say an agent is talking 50 Minutes per hour), the time a caller has to wait in the queue decreases inversely proportional to the number of agents and the talking time. For example, if you only have one agent in one branch office that picks up calls, callers will for example wait 100 seconds. If you virtually group four agents from four branches, callers will only have to wait 25 seconds to get served, because the probability that an agent gets free is increased as you add agents. Every agent will still be talking 50 Minutes per hour, but the caller (your customer) will not have to wait any longer. Here is a free Erlang calculater for Excel without warranty: erlang97.zip Skills Based Routing![]() Instead of having one agent dedicated to one language or one group only, you can use Skills based Routing. This will allow you to assign several Skills to an agent, effectively pooling resources and thus reducing waiting time and increasing productivity of your agents. Another positive effect of Skill Based Routing is that you can define at a very granular level what type of agents will best be able to pick up that particular call, thus increasing customer satisfaction. Integrating Back Office Tasks
The graphic below shows a typical call volume over the time in a callcenter. At certain moments, you have call peaks where your clients will have too long and regions of low volumes where you pay agents for not doing anything.
In call peak situations where you have a high call volume, you can use Voice Self-Services more extensively.
