Organizational structures are created by business leaders. A constellation of specialists in theory can be very productive for modular codebases where the work is distributed intelligently.
Conway’s Law is “[a]ny 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 indirectly asserts that the Unix philosophy of having things be modular is achievable best by loosely-coupled groups rather than tightly-coupled groups (such as an aggregation of mini-groups into one business unit) according to WhatIs.com.
