Rankings
Based on our studies, we regularly publish rankings of the “best consultants” and the “best auditors” from the perspective of the decision-makers surveyed. For this purpose, we continuously talk to executives from major German companies – board members, heads of specialist departments, sponsors of consulting engagements, and project managers. Their experience and evaluations form the foundation for our rankings.
In the following we have compiled some of the most recent rankings for the leading management consultants, the most important specialist consultants and the major accounting firms. In order to keep the data as easily comprehensible and comparable as possible, we have chosen a uniform presentation in all rankings: 100 percent corresponds to the maximum achievable value and thus an excellent attribution of competence. The intervals between the consultants are not always statistically significant and should therefore be understood as a tendency statement.
Since it is our aim to identify those consultants who are perceived as particularly effective in the market, but not to discredit particular consultants, we have only listed the five best consultants in each category in all rankings.
We have compiled the most important questions and answers on a FAQ page for anyone who would like to find out more about the statistical and methodological basis of our rankings.

The most important specialist consultants
In this section, we look at medium-sized specialist consultancies that are less well known than the leading management consultants, but whose expertise in their field is certified by their clients as higher than that of the three “champions” McKinsey, BCG and Bain & Company. We refer to them as “hidden champions”.
