Responding to competitive pressures arising from digitalization, traditional companies are in-creasingly turning towards platform strategies to gain speed in the development of digital value propositions and overcome rigidities of pre-existing information technology landscapes. Based on a case study of the LEGO Group’s digitalization journey, this paper elaborates how brick-and-mortar companies can break away from a drifting information infrastructure and trigger its trans-formation into a digital platform. The case analysis conceptualizes information infrastructure evo-lution as a path-dependent process and develops a process model on the creation of a new ‘plat-formization’ path through mindful deviations by architects that guide collective action. This per-spective depicts the transformation journey as a process of socio-technical path constitution that is shaped by deliberate human interventions and emergent forces from path dependencies.
