The document discusses the need for radical or revolutionary change in organizations. It states that incremental changes will not produce the required magnitude of change to meet external challenges. A sudden, coordinated attack across processes, cognitive maps, and culture is necessary. Change is often resisted by organizations and their employees who prefer stability. Over time, rigid structures emerge that are unwilling or unable to change. Business process reengineering is presented as a management technique to implement revolutionary change through a radical redesign of core business processes. The case of Nokia undergoing radical change through a strategic partnership with Microsoft is provided as an example of such change being necessary to respond to disruption.
