As a Fortune 50 company in the Aerospace & Defense industry with 60K engineers across x countries developing products in the digital age, you can imagine the complexity. Effectively transitioning to a DevOps mindset required exploring the problem space by asking: How do we create value that supports the cyber-to-physical spectrum at scale? How can we create observability of the work system? Is it possible to give teams end-to-end visibility of flow? To answer these questions, we developed an approach that integrated lean, agile, and DevOps with sense-making and the science of socio-technical systems to attempt to peer into the unobservable.
