[!todo] Seed note. A starting point, not a finished note yet.
Team Topologies is a 2019 book by Matthew Skelton and Manuel Pais that gives an explicit vocabulary for organizing engineering teams around fast flow of change. It names four fundamental team types: stream-aligned (owns a slice of the product end to end), platform (provides internal services that reduce other teams’ load), enabling (a temporary coaching team that raises capability), and complicated-subsystem (owns a part needing deep specialist knowledge). It pairs these with three interaction modes: collaboration, X-as-a-service, and facilitating. The organizing principle is limiting each team’s cognitive load so it can own its work without drowning. It is a deliberate application of Conway’s Law: shape the teams to get the architecture you want. Connects to Systems Thinking. Seeded from the developer-productivity metrics notes.
