In his first appearance on ManagementCast, IMD Professor Cyril Bouquet described his mega dive approach; and the reasons why this is one the best ways to open up an inter-departmental collaboration within large organizations. But what do businesses actually need to launch a "mega dive" themselves?Bouquet says that "there are a few key factors that need to be in place," but advises that "the first one is the commitment of the top management team". Without executive buy-in, the process won't work. With it, he says, ownership and belief in the system will follow.Cyril Bouquet is a Professor of Strategy and Innovation at IMD.
