During his professional experience, the author observed the increased expectations towards the controlling function. If controlling is to maintain its influence in a company, it needs to adapt to the changes in management expectations.

The questions which were answered were "what does controlling involve and which factors influence the set-up of the controlling function in a company", "how are the expectations towards the controlling function changing over time and what is its value contribution", "how can the controlling function add value to standard reporting and budgeting activities" and "how can the controlling function add value to reorganization activities".
