Conway’s Law helps us design our team boundaries in the context of desired communication patterns but it also encourages us to keep our team sizes small, reducing the amount of inter-team communication and encouraging us to keep the scope of each team’s domain small and bounded.
Nice in concept, but it requires a larger group of people. Architecting for a team of 10 that has 4 major services would require 40 people, when only 12 total are available. The role of architect seems to be overlooked in this discussion. This might make sense because they should have a higher view as enterprise architect. Still the role of system architect would be desired for each team.
