Cross-Cutting Lessons
1. Human-AI hybrid outperforms pure automation. Klarna, Stitch Fix, and Synthesia all found keeping humans for complex cases improves quality.
2. Change management > technology. Repsol's 92% NPS and Morgan Stanley's 98% adoption came from structured rollout and training.
3. Start internal, then go customer-facing. JPMorgan and Coca-Cola built confidence internally first.
4. Data quality is the bottleneck. DHL used GenAI for data cleansing before analytics. P&G's centralized AI Factory handles data first.
5. Public perception matters. Coca-Cola's holiday ad backlash shows AI authenticity is a real concern for consumer brands.
