Preserve installation intervals so analysis does not attribute a component's entire history to its current machine.
Index
A component moved between machines carries its own history. Joining interventions to the equipment hosting it today assigns earlier incidents to the wrong asset and distorts operational analysis.
The unit of analysis determines the result
The relationship must use the installation interval applicable when the intervention occurred. Retain start, end, component identity and associated equipment. Conflicting dates or simultaneous installations should appear as inconsistencies for review rather than be resolved by arbitrarily choosing the latest record.
Configured transformation can suffice when the source retains events. Data engineering is justified for consolidating sources or preserving intervals absent from current records. Do not invent historical relationships from present location; distinguish reconstructed coverage and events without sufficient supporting evidence.
Requirements for comparing BI proposals
- Define which service instant determines association and keep that choice in the data contract.
- Show overlapping intervals and components with no known installation at event time.
- Allow analytical rows to trace back to intervention and assembly records supporting their association.
A check before using the measure
In a hypothetical scenario, one part occupied two machines during different periods. Check every intervention appears against the appropriate asset at that date. Add an event exactly at transfer and validate the interval-boundary convention. Correcting an installation record must generate a traceable new result version without concealing the change.
