In 2019, the Kibana platform team initiated a significant re-architecture project to address the growing complexities and limitations of Kibana's existing structure, which had expanded from three applications to over 100 plugins since 2015. This migration aimed to enhance Kibana's stability, scalability, and performance by restructuring millions of lines of code and collaborating with more than 15 engineering teams to transition all first-party plugins to the new platform, a task that was successfully completed by June 2020. The project emphasized building a collaborative culture through clear communication of project goals, establishing a detailed project charter, and defining clear roles and responsibilities to ensure coherence and accountability across teams. It also highlighted the importance of standardized processes, effective knowledge sharing, and regular progress tracking to manage the complexities of cross-team collaborations. Recognizing the need for motivation throughout the lengthy process, the team celebrated key milestones to maintain momentum and acknowledged the extraordinary collaboration and professionalism of all contributors.
