I recenti orientamenti nel campo dei sistemi di controllo direzionale sottolineano l'importanza di superare i limiti di una visione prettamente contabile della gestione, attivando un sistema di governo capace di programmare l'intera rete di processi aziendali, attraverso la responsabilizzazione, la cooperazione e l'integrazione tra le diverse strutture organizzative. Il volume si rivolge a dirigenti, responsabili aziendali, imprenditori, professionisti che, pur non operando direttamente nell'ambito di questa funzione, intendono partecipare al governo aziendale. 410 1$1001VAN0057786$12001 $aFormazione permanente.
