Process Leadership [the broken link was removed] by Daniel T Jones:
the most promising approach is to create a small team, led by a high potential executive, operating initially outside the normal departmental structure and reporting to the top. They must be free to challenge the conventional wisdom, the firm’s current assets and relationships. Their job is to evaluate the core value creating processes of the organisation from the standpoint of the customer, and to work out how to flow value to the customer smoothly and with minimum effort.
