Sebastian Zeiss joins us and shares the optimization of process being made at Deutsche Telekom: "If one of the field service agents needs technical information of a phone line. They would call the hotline and be like, I am at customer whatever, and can you please give me the following values; and then he would start writing it down on a sheet of paper.And now, what we do is, he just enters the phone number of the customer into the smart phone, and the rest is done by the smart phone."
