QUALITY AND TRACEABILITY
Find the records for the batch under investigation.
Relate the affected output to recorded operating conditions and available inspection results.
When a nonconformity occurs, the first challenge may be establishing when and under what conditions the product was manufactured. Process data are useful when linked to the correct batch, cycle or time interval.
QUALITY / MANUFACTURING RECORDS
Investigating a nonconformity requires preserving batch context.
Traceability is established when batch identifiers, measured conditions and inspections are linked by verifiable dates and product references.
IDENTIFY
Batch, work order, product, mould and production period.
REVIEW
Variables actually measured during the period being investigated.
COMPARE
Inspection results and documented process changes.
What can be analysed?
01
Production identification
Define how work orders, products, moulds, materials and machines are linked. The level of detail depends on the identifiers actually captured.
02
Process variables and inspection
Select process variables relevant to the defect being investigated. Retain inspection results, timestamps and acceptance criteria.
03
Review the affected period
Review events and operating conditions within the identified interval. Correlations may guide the investigation, but further verification is required to establish a cause.
QUALITY · FURTHER INVESTIGATION
How can rejects be recorded during production?
Reject counts are meaningful when associated with the product, relevant time interval and inspection criteria. Operators can record good and rejected parts through SMARTPRO at the machine, including defect categories when configured.
What information does quality assurance need?
Defining inspection times, quantities, order or batch identifiers and recording frequency helps relate results to process data. Recorded quality information can contribute to OEE monitoring during the shift.

A PLANT-FLOOR EXAMPLE
Before drawing conclusions.
If records identify a batch and time interval, the relevant context can be reconstructed. Claiming part-level traceability requires a persistent identifier across inspection and other applicable operations.
