The three modern product trends discussed are:
1. Design as an investment - Companies that invest in design outperform those that don't. Design should be considered an investment, not just a cost.
2. Product decisions should be based on evidence from design research - Relying only on experience and assumptions is misguided; product decisions benefit from qualitative and quantitative user research data.
3. Empowering small teams - Large, centralized teams are less agile than small, cross-functional teams empowered to make decisions based on evidence from research.
