Quality control process in the manufacturing industry

Purpose:

Quality control aims to ensure the quality of raw material, bought-out parts (BOP) and the final product.

Scope:

Inspection of incoming material (Bought out Parts, Raw material and material being received after job work), in-process material and finished material.

Responsibility:

Head QA is responsible for Inspection activities at all stages

Quality Control Process Steps:

  • Incoming inspection
  • In-process inspection
  • Final Inspection

Incoming Material Inspection Procedure (Raw Material, Bought Out Parts, Job Work) :

  • Receive goods inward receipt (GIR) from the store
  • Select a sample, inspect the material and prepare an inspection report
  • If part OK, Clear GIR and send to store
  • In the case of NG, Forward the inspection report to the Head QC
  • Review the inspection report and mark the decision
  • Reject / Accept under deviation /Hold /Rework/Segregation
  • Raise a quality problem countermeasure report QPCR to the supplier as per supplier rejection criteria and ensure required action(s) are taken by the supplier: Sort the material at our works. Rectify the material at our works. Collect rejection back
  • If rejected or accepted under deviation, decide on GIR if held. Mark the decision on GIR Rework/Segregate.
  • Get the material reworked/segregated by the supplier or in the plant.
  • Inspect the reoffered material after rework/segregation.
  • Follow up with a supplier in case of QPCR sent
