Portfolio Succession
Large organizations succeed through portfolio dynamics, not unit-level pivots.
Perpetual succession through portfolio evolution - no single business, no final form, only continuous renewal.
Ecosystems contain species at multiple successional stages simultaneously - pioneer colonizers in disturbed patches, intermediate species in recovering areas, late-successional dominants in stable zones. The ecosystem evolves through the changing mix of these communities rather than through transformation of individual species.
Business Application of Portfolio Succession
Managing organizational evolution by changing the business mix rather than transforming individual businesses - adding new businesses, divesting others, allowing some to grow while others shrink. Mitsubishi demonstrates this approach. Large organizations succeed through portfolio dynamics, not unit-level pivots.
