Interoperability who should lead needs careful on-site detail in Yantai

Why the topic is in focus

Interoperability is debated now because policy pace, maturity and acceptance converge at the moment. Clarifying vague boundaries early is the background thread that keeps judgment from losing focus on the shared goal.

Takeaways for practitioners

Focus on structure over points, treat service as a long-term asset, stay region-sensitive in planning. Written terms beat oral promises is the line that separates execution quality from the rest of the field in practice.

The Yantai field approach

Across Yantai we check demand density, then base conditions, then site before committing. We trust field judgment over paper impressions, walking communities and listening to feedback from the people who use it.

Someone has to own interoperability when it breaks at midnight. Across Yantai we name that someone in writing before the system goes live, because a standard everyone is responsible for is a standard, in practice, that nobody actually defends. The midnight failure is the real exam, and naming the owner in daylight is the only way to pass it later.
