The Strategic Business Unit structure made each division accountable for its own profit and loss, which encouraged short-term optimization within each silo at the expense of the cross-divisional learning that produced long-term competitive advantage. The result was organizations that looked efficient on paper — each division optimized for its own market — but were strategically hollowed out, unable to combine capabilities across divisions, unable to enter new markets requiring cross-divisional collaboration, unable to develop the integrated capabilities the next generation of competition would demand.
