This recommendation is meant for all engineers, engineering students, high school students and persons from industry and science who wish to acquaint themselves with the occupational profile of a sales engineer. The guideline offers this target group a comprehensive insight into the various de-mands the sales engineer must meet and the tasks he has to fulfil, and reveals why the sales of capital goods and the management of customer relationships in industrial business-to-business transactions require not only engineering knowledge but at the same time - and to the same degree - sales and marketing knowledge.
