An appropriate and optimum flow of parts and materials must ensure that mixing / confusion between similar items cannot occur. Poka Yoke or other methods may be used for this. The use or fitment of an incorrect part or material must be immediately
detectable and must not proceed further in the value creation process. Suitable checks/actions must be carried out to guarantee early detection and filtering out of items wrongly installed items.
Associated subjects and actions must be included and examined in the Process FMEA and, if appropriate, in the Product FMEA.
There must be a clearly controlled process for handling residual quantities, parts which have been separated out (for example, stacked up because of a machine problem), re
