 The study explores mechanisms that support or inhibit the exchange of inter-organizational digital transformation knowledge in the English global digital exemplar, GDE, program, finding that formal processes put in place by the GDE program accelerated the growth of informal knowledge networking and helped establish the foundations of a learning ecosystem. The benefits of networking were enhanced when supported by informal networking driven by shared culture and context, common technological functionality, regional and strategic alignments, and professional agendas. Policy interventions need to enhance incentives and reduce barriers to sharing across the ecosystem, be flexible in tailoring formal interventions to emerging needs, and promote informal knowledge sharing.
