IQC & Warehouse
Does the receiving area include space for hold, reject, and sort/rework areas with clear identification?
At IQC area, is its partition well defined for segregation, materials under inspection is labeled and status is tracked for timely disposition?
Does the SIP include procedure, sampling plan, test method, instrument, fixture, visual-aid, quality concern, etc? It is preferred to be specific on individual parts as well as the report format.
Is the content of SIP from studies of engineering specification, manufacturing process and future application to determine its coverage and sampling plan?
Does the inspection report include part number, date, lot number, purchase order number, total quantity, test quantity and data as well as MRB?
Is standard such as limit sample and color chip well preserved and managed with shelf life control?
Does inspection fixture conduct gauge R&R to ensure accurate result by qualified inspector?
Does the inspection result has proper disposition and is used for vendor management?
Does the approved label show receiving date, quantity, part name, part number and inspector? It is preferred to use color label on each carton/container for control of shelf life and FIFO.
Is a closed loop corrective action (SCAR) issued once materals is failed on IQC inspection?
Is MRB process performed on nonconforming material if requested? A logical process flow and MRB reviewed/approved by eligible representative at management level is required.
Does statistical method apply on property/process of critical parts once it was identified as mid/high risk in quality?
Is process for sub-tier vendor selection & management well defined with report/rating provided to procurement for reference?
In warehouse, are all materials at assigned location and well preserved for easy retrieve? Using bin card is preferred.
Is inventory managed on first-in/first-out, quantity, shelf life at finished good warehouse and audited at least every six months? A computerized system is preferred.
Is storage condition monitored on materials/finished goods that needed special care (temperature and humidity control)?
