In order to succeed at production ownership, a team needs a roadmap for developing the necessary skills to run production systems. We don’t just need production ownership; we also need production excellence. Production excellence is a teachable set of skills that teams can use to adapt to changing circumstances with confidence. It requires changes to people, culture, and process rather than only tooling.
Even a perfect set of SLOs and instrumentation for observability do not necessarily result in a sustainable system. People are required to debug and run systems. Nobody is born knowing how to debug, so every engineer must learn that at some point. As systems and techniques evolve, everyone needs to continually update with new insights.
