Conway's Law
Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.
Conway’s Law is considered a driving principle of software management. Once an engineering organization is split up a certain way, its products will tend to reflect the org chart over time; it follows that org chart changes must be considered carefully. The inverse Conway maneuver attempts to flip the logic of this law on its head, by designing org charts that promote a desired software architecture. Arguably, the microservices revolution is an example of such a maneuver.
