Nonconformity: The nonfulfillment of a specified requirement. Also see blemish, defect and imperfection.
Đăng bởi: Productivity and quality managementNonconformity classification, classification of nonconformities
Classification of a units potential nonconformities into nonconformity classes. The evaluation depends on the effects of the nonconformity. Internationally, nonconformities are divided into three nonconformity classes: Critical nonconformities: Major nonconformities Minor nonconformities. (On the basis of DGQ Volume 11 04:2012)
Đăng bởi: Productivity and quality managementNonconformity costs, costs of nonconformity
Also called cost of failure. Costs resulting from a nonconformity. Nonconformities result in costs. Nonconformity costs can be divided into two groups, depending on where they were found: internal nonconformity costs and external nonconformity costs. An organization should define what it sees as internal and external failure costs. DIN 55350 11 gives these examples of nonconformity costs: Costs for remedying or mitigating a nonconformity, for rework, repair, scrapping, disposal, handling of rejects, unplanned sorting test, repeated inspection, downtime, guarantee and product liability.
