Few professions are as controversial as that of the management consultant: on one side, the detached theorist and ruthless cost-cutting expert who knows better than anyone else without needing to ask, and on the other side, the helper who makes businesses competitive again and thus secures jobs. The public perception in society and the economy also depends on the consultant's demeanor. This guide addresses this by providing specific tips and advice for newcomers in the consulting field on which (often unspoken) behavioral rules to observe. Through concrete examples from practice, the reader receives guidance on appearance, behavior, language, and communication in the daily life of a consultant. The book has been summarized by getAbstract and rated with the highest score of 10. It is aimed at all management consultants and others in the field.
