Build the Sensor-to-Decision Trace
Create a trace from physical asset signal through digital model to decision action.
A bottling-line twin recommends slowing line 4%, but the team cannot explain which physical signal produced the recommendation or how the operator should verify it. ISO 23247 trace: physical element -> observed data -> digital representation -> twin service -> operational decision The common trap is collecting many tags and assuming the recommendation is explainable because the data exists. Without a trace, unused tags, wrong units, stale transformations, and unsupported recommendations stay hidden. Physical state Name the real-world state: filler nozzle fouling may be increasing underfill risk on line 2. The trace starts with a physical condition, not a tag…
