In a dynamic cloud environment, reliable operations depend on trusted, well-structured service data. We've helped a major French aerospace group restore service info confidence by implementing a clear, standardized data model connecting technology to business outcomes. Through a progressive, adoption-driven approach, we guided teams from theory to practice, restoring visibility, improving collaboration, enabling faster, reliable decisions. This session shows how disciplined service data management transforms the CMDB from a tech repository into a true foundation for performance and resilience.
