3) Review the process.
a) Preparation and planning: This stage is very important, because the products of each arrangement are different, so how to develop work instructions for reviewers to use and train reviewers according to the products of this arrangement is the key work at this stage. To this end:
Drawings with changed conditions, technical specifications, FMEA, process documents, process descriptions, inspection specifications, defect catalogs, specification samples, appraisal method rules (including defect classification and identification), appraisal specifications, quality specifications, data sheets, approved production deviations, specifications, regulations, supply agreements, etc.
When selecting inspection methods and testing equipment, it is necessary to pay attention to: the unreliability of inspection, measurement and test equipment, so it is necessary to analyze the measurement system; When there are a variety of inspection methods to choose from, the methods that have not been used in bulk production should be selected because of the shortcomings caused by the error or unreliability of the monitoring equipment; If the standard model is used as the inspection principle, the review personnel identification training should be strengthened, and the sample should be reviewed frequently or regularly, and the calibration records should be kept and the reviewers should be exchanged.
The products to be reviewed must have their own work instructions, and if they are common products, their common parts agree to share a work instruction. In the work instructions, it is necessary to state the purpose of the review (e.g., whether to review or comment on the quality of the product, etc.), the product to be reviewed, the frequency, the sampling method and quantity, the reviewer, the review statement and the sample of the checklist, the scoring specification and the calculation formula.

First, samples are taken from the products that have been inspected and qualified (generally taken in the product warehouse). The reviewer then checks it against a checklist and finally forms a review statement (formatted). Indicate where the correction is made and the part that has the responsibility to correct, agree on the method of eliminating the shortcomings, and record it in the statement of the corrective solution. If a defect that threatens safety is discovered, emergency measures should be taken immediately to prevent the use of defective products. Dongguan.
