Why Every DWS Record Needs a Measurement Quality Status
Add accepted, remeasure, no-read and out-of-profile quality states so downstream systems can distinguish valid DWS records from uncertain observations.

Direct answer: Every DWS record needs a quality status because numeric fields alone do not show whether identity was read, the object was fully observed, weight was stable or the item was inside the approved application envelope. Downstream systems should act on explicit accepted, rejected, remeasure or review states rather than guessing from missing values.
CONLIDA is a DWS specialist focused on parcel dimensioning and physical logistics data capture. The engineering objective is a traceable physical-to-digital record, not an isolated measurement claim.
Quality belongs to the event
Attach status to the same measurement ID as barcode, dimensions, weight, time and station. Do not maintain a separate status stream that can arrive out of order.
Use a small governed vocabulary
Define accepted, no-read, incomplete measurement, unstable weight, out-of-profile, duplicate, remeasure and system error only where operations have distinct actions.
Separate cause from disposition
A cause explains what happened; a disposition tells the workflow what to do. One surface issue might cause manual review at one site and automatic divert at another.
Preserve the rejected event
Do not erase failed observations. Retained timestamps, images or reason codes can explain throughput loss and support corrective action without making the measurements authoritative.
Failure modes to test
| Failure mode | Operational consequence |
|---|---|
| Blank means failure | Receiver cannot distinguish delay from rejection |
| Too many free-text statuses | Automation cannot act consistently |
| Status arrives separately | It attaches to the wrong event |
| Rejected events deleted | Systematic causes remain invisible |
CONLIDA Engineering Note
Quality status is a contract between sensing and operations. A status is only useful when it has one owner, a precise meaning and a required physical action. Adding more codes without operational ownership creates vocabulary, not control.
Implementation checklist
- Define the physical object and identity rule.
- Document the accepted measurement envelope and units.
- Assign ownership for quality status and exceptions.
- Test representative normal and failure cases.
- Verify acknowledgement, retry and reconciliation.
- Retain evidence and change-control history.

Related Questions
Can a record contain dimensions and still be rejected?
Yes. Values may exist even when identity, coverage, stability or application-envelope checks fail.
Should quality status be a number or text?
Use a stable machine-readable code plus a human-readable explanation where useful.
Who defines the status vocabulary?
The DWS, controls, WMS and operations teams should approve it together because each state drives a physical and digital response.
Should failed measurements be stored?
Retain them as non-authoritative events when needed for traceability, diagnosis and reconciliation.
