This document discusses the evolution of operational models in shipbuilding from traditional subcontracting models to more vertically integrated value chain models. The traditional model involves multiple subcontractors with rigid overhead structures and profit margins built into each subcontract. Newer models proposed include a leaner network alliance model with individual project organizations and earnings based on roles. The ideal model presented is a holistic and continuous value chain integrating operations, construction, maintenance, research and other functions to create strategic partnerships throughout the chain. The goal is to move from a disconnected value net to an integrated vertical value chain.
