hub-and-spoke

The term is a modern metaphorical compound, directly borrowing its imagery from the mechanics of a wheel. The word 'hub' evolved from the earlier 'hob' or 'hubbe', denoting a solid, central lump, and became specifically associated with the central part of a wheel in the 17th century. 'Spoke' has Old English origins, referring to the radial bars that give a wheel its structure. The compound 'hub-and-spoke' emerged in the late 20th century, primarily in logistics and air travel, to describe a network design where all routes (spokes) converge on a central transfer point (hub). This model replicates the efficiency and centrality of a physical wheel, transforming a simple mechanical description into an abstract principle of modern systems organization.
