Facing the opportunities and threats arising from digitalization, traditional brick-and-mortar companies are increasingly following the lead of digital natives and turning towards platform strategies to gain speed in the development of digital value propositions internally and co- create value in their surrounding ecosystem. This research project elaborates on the digitalization journey of the LEGO Group to investigate how companies can architect digital platforms to overcome previous limitations to digital innovation. Portraying Enterprise Architecture (EA) as a central mechanism to guide the transformational journey, the research elaborates how this dynamic capability can be built. Subsequently, a path constitution perspective reveals how a company can re-architect its pre-existing information infrastructure into a digital platform. The research project will be rounded off by articulating how this transformation removes previous barriers to digital innovation.
