Linking product modularity to supply chain integration in the construction and shipbuilding industries

Modularity is gaining relevance within Engineer-to-Order (ETO) industries such as construction and shipbuilding. So far, however, the concept of modularity does not seem to have fully captured all the facets within these specific industries. Yet, the impact of product modularity on Supply Chain (SC) integration is still an open issue. We investigated the concept of modularity within the ETO industry, by means of an explorative case studies approach. Some observations have allowed us to clarify the meaning of modularity within the ETO industry. Moreover, the relationship between modularity and SC integration has been examined, and a number of contingent variables - e.g. customization, IP awareness, innovativeness, company and product size - have been identified. These variables are able to affect the level of both product modularity and SC integration. The highlighted relations build a basis for further research steps using survey-related instruments.
