The strong instinct of most corporate leaders, faced with the teeming diversity not just of gender, race, and age but of thought, drive, and relationship inside their organizations, is to look for some way to exert controlâto rein it all in, to impose conformity on the chaos, and thence to be able to understand whatâs going on, and to shape what will happen next. And so companies have spent, and continue to spend, large quantities of time and money trying to work around each personâs uniquenessâand this is where these models bubble up from.
