to summarize feature teams vs. empowered product teams: Feature teams are cross‐functional (a product manager doing mainly project management, a product designer, plus some engineers), and assigned features and projects to build rather than problems to solve, and as such they are all about output and not business results. Empowered product teams are also cross‐functional (a product manager, a product designer, and engineers), but in contrast to feature teams, they are assigned problems to solve, and are then empowered to come up with solutions that work—measured by outcome—and held accountable to results.
