The Value of Consultancy
"In significant, often far-reaching changes within a corporation, advice from an external partner who is both a sounding board and a proactive creator of ideas is of utmost importance. His experience helps to thoroughly investigate problems in a balanced way, to reconcile them with external experience and to evaluate them from different perspectives. His value is generated from the fact that he is not constrained by day-to-day business issues".
Dr. Hans-Peter Kohlhammer
