Topology Without Topography: The Vertical Reading of Conway's Law

What Conway's Law says beyond the familiar line that organisations ship their org chart. Melvin Conway's 1968 paper How Do Committees Invent? establishes a correspondence between the architecture of a system and the structure of the organisation that designs it. Its reception, from Brooks's The Mythical Man-Month to Skelton and Pais's Team Topologies, has kept that horizontal correspondence between teams and lost the vertical reading Conway develops beside it: how management practice on short cycles fragments an organisation across its layers, and the fragmentation passes into the artefact it builds. The paper recovers that reading through a distinction between topology, the structure a chart, a framework or a dashboard can carry, and topography, the lived ground of tacit knowledge and mutual understanding among specific people on which the chart's labels sit. Using Harsanyi dividends and cooperative game theory, it proves that per-role valuation is blind to topography; it states a horizon-mismatch bound for regulators acting faster than the ground replenishes; and it gives a cannibalisation theorem under which measured output can rise while drawing on a falling relational stock. The Boeing 737 MAX and Wells Fargo serve as its cases, with Bill Bernbach's pairing of copywriter and art director as the counterexample, and the paper closes with the disposition the diagnosis implies and what a framework could still be. The paper reads Conway's Law through the results that The Post-Cybernetic Organisation and its companion papers develop.
