“Gemeinsam mit Dr. Tom Siebenaler haben wir bei der Münchner Sicherheitskonferenz Karrierewege für insgesamt 7 Job Profile (z.B. Digital Communication Manager) gestaltet und weiterentwickelt.
In mehreren Workshops mit unseren Führungskräften wurden verschiedene Karrierelevel (Junior-Experienced-Senior) ausdifferenziert, Kriterien zur Beförderung (engl. promotion indicators) entwickelt sowie Kompetenzanforderungen definiert.
Dabei waren die Ergebnisse sehr konkret und auf uns zugeschnitten.
Vielen Dank”
