The advisory board was established in 2006 to provide additional assistance to the board members. It is an institution which - unlike the annually altering board - provides support considering the club’s aims for a longer period of time.

The key tasks of the advisory board are:

  • arrange contacts in the economic sector, the advisory board is often able to operate as a „gate-opener"

  • the discussion of strategic questions with the respective board

  • outward representation of the club, especially towards public institutions like the University of Cologne an KölnAlumni

  • the activation of the alumni-network (in addition to the alumni-team)

The advisory is not a decision making institution, but rather a consultant to the respective board.Primarily because of the continuous work, which goes beyond the one year term in office of a board, the advisory board has a big Know-how, which can be useful in major decisions such as bigger financial investments.
