Remote operations projects most easily fall into two extremes. One is wanting, from the start, to cover all equipment, all sites, and all processes, so the scope runs out of control. The other is turning the sample unit into a long-term free trial, so neither side has a real commitment to delivery and use. Tongwei Smart recommends using a paid PoC to verify equipment access, alarms, and the service process first. The more reliable approach is to start from a paid PoC with a defined scope.
A good PoC is not a reduced version of a "free large project." It is one business experiment that can be verified. It should limit the equipment model, the number of protocols, the key points, the network environment, the alarm rules, the page scope, the work-order process, and the verification period. At the same time, it should agree on the responsibilities of both sides, the acceptance criteria, data permissions, and the conditions for later expansion. The customer uses a smaller investment to verify whether the solution fits the site. The supplier uses a real project to confirm access labor hours, data quality, alarm effectiveness, and service value.
For an equipment manufacturer, a PoC can verify whether equipment connectivity, fault reporting, and remote after-sales can reduce ineffective communication. For a multi-site operations provider, it can verify whether alarms, work dispatch, inspections, and reports can be run through. For an operator of new-energy stations, it can first verify multi-brand equipment access, offline alarms, and monthly work-order reports, rather than going straight to a complete platform.
Tongwei Smart recommends the delivery path of "requirements diagnosis-sample unit/PoC-standard pilot-batch replication." Each step produces a point list, an interface scope, an alarm strategy, account permissions, acceptance records, and a follow-up route, so a configuration that succeeded can be retained as a faster delivery the next time.
The point of charging is not to raise the amount of the first order. It is to move both sides from "watching a demonstration" to "verifying value." When the customer is willing to put budget into one defined operations problem, the project actually has a basis for productization and replication.
