Great product management is not about mindlessly shipping features, but about building an empowered team that discovers and solves real customer problems.
Empowered product teams are composed of cross-functional members who are given specific problems to solve instead of a predetermined list of features to build.
Continuous product discovery is essential to test assumptions early and separate good ideas from bad ones at a fraction of the cost of full development.
Product managers must possess a deep understanding of their customers, data, and business constraints to guide their teams effectively.
