Testing is a quality control to detect the defects, and correctness proof discovers defects at coding stage. The AOI industry is striding toward the final goal of zero-defect manufacturing, but it is not there yet. Your QC checklist for garments should outline dimensional tolerances for the product, any on-site tests you require during inspection and packaging specifications. #1) Defect Prevention: Defect Prevention is the best method to eliminate the defects in the early stage of testing instead of finding the defects in the later stage and then fixing it. 2.

A flaw or weakness in a system that causes the system to fail; Non-conformance to a standard; A disorder in the system or process which can cause a failure or discrepancy in the delivery of product or services. Quality appraisals are therefore appropriately the first items recorded on the classification form. In the software development context test candidates can be specifications, design descriptions, code listings, executable software modules, units, subsystems or complete systems. This approach is not binding as the classification takes also into account the context of the finding and the quality history of the site. Quality management. In garments industry these defects are dependent upon the classification of defects and an inspector’s ability to make decisions.
