Gary Hamel and Michele Zanini, cofounders of the consultancy Management Lab, say that even though we all lament how rigid, parochial, and time sucking bureaucracies can be, they still seem inescapable. The managers who’ve excelled in them often don’t know how to dismantle them — or else they don’t want to. But Zanini and Hamel have studied and collaborated with innovative organizations, and they outline bottom-up ways to empower workers and hack management. Hamel and Zanini wrote the new book “Humanocracy: Creating Organizations as Amazing as the People Inside them.”
