History must record installation, removal and observed condition without allowing one component to appear installed in two assets.
Index
Knowing a serial number is insufficient when a component moves between machines; lookup must show where it was installed.
The rule that changes the scope
History must record installation, removal and observed condition without allowing one component to appear installed in two assets.
Asset software can register serials; a custom module organizes assembly events and lookup by machine or component.
A serial number may come from the manufacturer or be assigned internally, but it needs a coherent uniqueness rule. Similar parts are not interchangeable by inference. Demonstrate lookup of a removed component not yet checked: it must not appear available merely because it left a machine. If identification is corrected, retain the relationship between the earlier and current code so historical interventions remain findable by staff.
Specify operational deliverables
- Associate the component with its equipment and installation interval.
- Separate removed parts from those available for reinstallation after checking.
- Retain the previous association when moving a component to another asset.
Test the exception before acceptance
In a hypothetical scenario, a user tries installing a part still recorded in another machine; the system must resolve the existing association before confirming.
