How to Develop Product Expertise

Teresa Torres argues that product managers and hiring managers often chase breadth, trying to be good at everything and ending up mediocre. She proposes a three-tiered approach: build foundational attributes that make new methods easy to adopt, concentrate on one or two areas of depth where you can have the most leverage, and cultivate the right mindsets at individual, team, and organizational levels. The piece matters because it reframes skill development and hiring as a deliberate focus problem rather than a checklist of competencies.

01Key takeaways

• Stop dabbling across every product skill; choose one or two areas to become genuinely strong in.
• Build foundational attributes like empathy, curiosity, and statistical competence to adopt new methods quickly.
• When hiring, recruit for the depth your team desperately needs rather than seeking generalists who do everything.
• Assume you are probably wrong and use experiments to test that assumption before committing.
• Mindsets only stick when incentives and organizational behavior support them, not just individual effort.

The problem with trying to do everything

Hiring and self-development both tend to chase every skill a product manager might need, which leads to mediocrity. The author argues this scattered approach is not a viable way to get good at anything.

Focus on the fundamentals

Fundamentals such as empathy, active listening, curiosity, and statistical competence are prerequisites that make specific methods easier to learn. Torres gives examples of how they helped product managers adopt customer development and A/B testing.

Identify areas of depth

No one can excel at every product activity, so individuals and teams should pick one or two areas of leverage and develop real expertise there. This creates distinctiveness for individuals and an advantage for companies.

Cultivate the right mindsets

Drawing on Stanford's d.school, Torres describes human-centered, experimental, collaborative, and metacognitive mindsets. She notes these must exist within individuals, across teams, and throughout the organization to be real.

“How do you evaluate how someone will contribute to a product team? How do you develop your own skills to ensure that you are contributing the most to your product team? Whether you are looking to hire someone or you are looking to improve your own skills, I see people”
