BMW Group's approach to data streaming highlights the importance of building a vibrant internal community alongside adopting new technologies. Initially facing challenges such as siloed teams and fragmented knowledge, BMW shifted from a purely technological focus to fostering a cross-functional community that empowered teams to own and leverage data effectively. By creating a central data streaming service and organizing flagship events like the Streaming Wiesn, BMW facilitated knowledge exchange and collaboration among over 10 business units globally. This community-driven strategy accelerated the adoption of more than 1,000 applications and 40,000 topics, enhancing innovation, resilience, and governance. The collaboration with Confluent further supported this transformation, demonstrating that successful data streaming is as much about engaging people and processes as it is about technology.
