Executive management shapes a company as a whole, makes a difference, and drives successful developments and changes through the establishment, enforcement, and application of a success model. This book illustrates how this manifests in practice. The fundamental ideas of a success model are systematically introduced and explored through the example of one of the most discussed corporate restructurings in recent years - the transformation of the chemical company Hoechst into Aventis and Sanofi-Aventis. Simon Grand and Daniel Bartl describe the relationship between executive management and corporate success and develop perspectives for entrepreneurial executive management.
