It is the same in the electronics industry, far too often the front line technical help desk agents are no more trained up than the average field engineer. They certainly have less hands on experience unless they have come in from the field. Those that have had extensive hands on experience tends to be place in the second line.Bernard, that is why we have manufacturers technical helpdesk available to us, who themselves fail to understand their own appliance sometimes.
Are these experts really experts or are they just buffers with a scripted screen to read out to the caller. It may be they only have a copy of the fault finding flow chart on their screen. The real experts, the designers and others who fully understand the equipment are not those who answer the help desk phones.Just because an expert is available on the makers help desk number, does not mean he/ she knows what is going on or have understating of appliance function or sequence if operation
That is probably part of the script on the agent's screen when (s)he answers the call. With calls being recorded the agent has to follow the script if thery want to keep their job. Knowing the name of a real expert one level above the help desk can be useful.the ones i've ever spoken to want your gas safe number before they'll speak to you
