18/ I think the fundamental problem here is that Conways Law is descriptive and Inverse Conway Maneuver is normative.
Conways Law says that this tends to be true, or more explicitly: It was a pattern Conway himself observed.
Inverse Conway Maneuver is not an observation of actual teams producing actual software, it is a thought experiment mostly concerned with answering a question that has not been asked: How does a reorg affect architecture?
