Phase 01

Disruption

Investment costs exceed near-term gains. Learning and experimentation dominate.

Phase 02

Reorganization

Complementary investments in process, talent, and data infrastructure mature.

Phase 03

Acceleration

System-level redesign unlocks compounding returns beyond pre-AI baseline.
