Interoperability long run impact needs on-site handling from Yantai practitioners

What the signals actually show

Through public compiled figures, interoperability change is stacked factors, not a sudden event in the market. Comparing once and avoiding repeat rework is cheaper, and structural change beats total volume for interpretation by planners.

Constraints that get underestimated

Grid conditions, site resources and staffing still cap what is feasible on a given site. Reserving margin to cut later cost is the underrated constraint that, priced in early, steadies the overall plan against later trouble.

Pacing the development zone rollout

In the Yantai development zone we avoid one-shot spread across the whole area. Pilot a sample, smooth the process, then widen. We would rather slow down than let maintenance fall behind, since reputation rarely returns.

Interoperability fails in the commas of the contract, not in the demo. In the development zone we write the exception owner before the sign goes up, because a roaming user who cannot get help is a user who will not roam back again.
