This document discusses feature team construction and components. It defines a component team as focusing on creating reusable components like system layers, modules, or packages. A feature team is cross-functional and can pull features from the backlog to complete. Challenges include organizational silos and technical reusability. Some patterns to address these are understanding the full value stream, improving infrastructure for quicker feedback, using communities of practice to share knowledge, and developing T-shaped skills with depth and breadth.
