Factors Leading to High Failure Rate in Non-standard Items

Factors that contribute to the high failure rate for non-standard items are:

• Poor uniformity of manufacture in small production runs. Consequently, parts are needed to be ordered more frequently, increasing the logistical burden. Also, small production runs could make the parts more difficult to obtain.
• Incorrect use, application, handling, installation, or maintenance of parts and components since they are less familiar to workers.
• Lengthy storage periods for items for which there is low demand and the resulting deterioration of the items during this time.
