Full Description
Das Buch von Eva-Maria Kraus zeigt auf, wie Führungskräfte ein strategisches Netzwerk aufbauen. Krisen wie die Corona-Pandemie haben gezeigt, dass wir nur gemeinsam im Miteinander zu auch langfristig erfolgreichen Lösungen kommen können. Hier funktioniert kein Silodenken oder das Kleben an traditionellen Hierarchien. Eva-Maria Kraus ist überzeugt: Nur durch die Schaffung einer Kultur des Miteinander und Füreinander werden Unternehmen gerüstet in die Zukunft auch nach Corona gehen können. Hier sind die Dynamik und Kraft von strategisch vernetztem Arbeiten essenziell.
Durch handlungsorientiertes Netzwerken innerhalb und außerhalb des Unternehmens werden Probleme effizient gelöst. Einzelne Mitarbeiter aus allen hierarchiefremden Abteilungen und eventuell Kunden arbeiten gemeinsam mit anderen an ihren Projekten. Die Auswirkungen auf die Gesamtorganisation sind mehr Effizienz, mehr Vertrauen untereinander, mehr Sicherheit im Tun und eine neue Orientierung. Die Komplexität der Aufgaben wird reduziert und die Führungskraft hat wieder die Macht als treibende Kraft zu agieren. Zukunftsweisende Themen werden miteinander verbunden und das Zusammenführen unterschiedlichster Kompetenzen und Disziplinen sorgt für mehr Freiraum. Durch die Veränderung der Zusammenarbeit kann auch die Unternehmenskultur und -struktur verändert werden, um zukunftsfähig aufgestellt zu sein.
