17/ If there exists a team or person that can produce a system with an interface (for example an API or one or more collaborating micro services or even a layer of abstraction), then such a team or person would be a violation of Inverse Conway Maneuver, they have produced a system with "communication structures" that are not a reflection of their organizational "communication structure".
Or if there exists a group of teams that build a system without interfaces, since such a thing does not exist we'll just call it a monolithic system. Then that is also a violation of such a statement.
