Define the boundary before comparing
A voyage-only estimate differs from one that includes port waiting, auxiliary equipment or upstream fuel processes. Units and system boundaries must accompany the result.
Connectivity helps teams assemble records, but cannot repair incompatible definitions.
Separate live signals from reviewed records
Sensors can stream continuously while formal reports require validation and a frozen version. Live changes should not overwrite an approved submission.
Outliers need their original record and a documented treatment rather than silent removal.
Evidence should support action
Traceable data can reveal opportunities in waiting time, equipment use and voyage planning.
