Prefabricated housing is a disruptive innovation struggling to take hold in a traditional complex product system (CoPS). It is quicker to produce and has improved environmental performance compared to traditional housing. CoPS have more dense and complex network connections than commodity industries, making disruptive innovation more difficult. Effective relational capabilities can achieve the coordination necessary to address this challenge. The prefabricated housing industry needs to develop a structure that drives these capabilities. Using a case study methodology, the structure of the industry is examined in two contrasting countries, namely Australia and Sweden, as they represent an early and late stage of industry emergence, respectively. A new framework is proposed for this purpose, enabling a repeatable, orderly and comprehensive disaggregation of industry structure to examine the latent drivers of relational capability. The main empirical contribution is to (1) describe an industry that is yet to be formally recognized by national statistical agencies and (2) show how the adoption of prefabricated housing can be accelerated. The study found that younger industries need a focused industry association with diverse membership to act as an effective system integrator. © 2019 The Author(s).
