Jason Yip shares his observations for scaling software teams during hyper growth (and what not to do). I liked his insight on group structure alignment with the stability of the group's strategy: "Structure should be stable where strategy is stable; structure should be flexible where strategy is volatile. For example, if a broader department-level product strategy is stable while more local tactics are volatile, you should want the structure and shared identity of the department to be stronger and more stable than team-level structures and identities."
