Query: Diverse Managers enabling knowledge-creating corporations

Very insightful review on what is required to be a master manager in today's global businessphere. Mr. Lessem re-introduces us to the four worlds of management--primal, rational, developmental, metaphysical--and how the four spheres--East, West, North, South-- and their combinations, linking core to periphery via a knowledege spiral. Excellent rendition on where organizations should be to accomplish constant renewal and transformation for survival.
