The ability for an agent to put themselves into the customer’s shoes. Many call centres lack empathy. The caller is just another caller and although the agent deals with the call as best as they can. With empathy the agent feels the same concerns as the caller “I know how you are feeling because I too….” would be a common phrase that perhaps shows empathy. It is also commonly confused with sympathy which is more of an “I hear what you are saying…” type of communication, but perhaps without the shared experience of what it is like to go through this condition. Empathy was a concept developed by the psychologist Carl Rogers (1902-1987)

The difference between empathy and sympathy is perhaps demonstrated by the expression of pity or sorrow to the distress of another.

“I offered my sympathy when I learned that Jane’s father died.”

Empathy, on the other hand, is usually meant to indicate that the person who is empathizing, knows what the other person is going through, and can identifies with the person.

“I can empathize with how Jane is grieving over her father’s death. I know exactly how she felt, because I went through the same thing when my father died”.

To me, the big difference between empathy and sympathy is that the person who empathizes can feel the distress on a personal level, whereas sympathy is less personal.


ERP – Enterprise Resource Planning

The means of determining staffing and occupancy levels for Front- and Back-Office staff.


FCR – First Call (Contact) Resolution

A measure of relative success for an individual interaction. Usually defined in terms of a single customer or account, a single issue or order and a predefined time range for a response to have taken place.

Example: If a customer choses a set of particular Options on an IVR or an Agent appends a particular Result Code to an Account and the customer contacts the supplier/provider regarding the same criteria within (7) days, then that interaction would have failed FCR. Usually expressed as a percentage of the overall interaction volume.


FTE – Full Time Equivalent

The equivalent headcount for one person working full time.

So 1 FTE = Somebody who works Monday – Friday
or 1 FTE = Two people who work half a day

In terms of the number of hours then one FTE could be either 37.5 hours or 40 hours per week, depending on the number of hours per week that you work in your organisation.

It is not quite clear how this could be used in a call centre environment. Does anyone have any ideas?

Interactive Voice Response (IVR)

A telephone system that lets callers interact with your company through either touch tone or speech recognition.

The IVR will ask the customer to press a button on their telephone key pad to select which service they want. The technology then routes the call to the most appropriate agent to handle the enquiry! Or it can ask customers to use their own telephone keypad to key information that will help the agent to validate who they are. E.g. account numbers.

While most systems are only programmed to give callers menus (press one for sales, two for support…) they can also be programmed to interact with a database to provide status information or to give you your account balance.

Here an algorithm is used to predict when an agent is likely to become free and dials in anticipation of this so that the non productive time that an agent spends between calls is minimised. Such equipment can also be used in preview mode, where the systems allocates the contact to an Agent for them to preview prior to physically dialling the number.

It typically comes about when a company outgrows its main building in the town centre and needs to expand.  Instead of moving everyone out of the old building it acquires a new building out of town. The two call centres are joined together, so they typically take the same calls, but are physically in tow different locations.

Not the storage area of a car, but a word to describe the telephone lines coming into a call centre.

This is one of the most baffling uses of jargon in a call centre, but effectively means an agent telephone set.

This term was commonly used in the 1980s and 1990s but is not so widespread today. Usually the term TeleSet is used these days.
