한국어Scrap rate
Concept
The share of produced units that cannot be sold or reworked and are discarded. It is a basic quality measure and also part of the quality factor in OEE.
Descrizione
The scrap rate is the share of produced units that are discarded because they cannot be sold or reworked. It is calculated as scrapped units divided by total units produced, usually per product, line or shift. It shows the material, time and energy that went into parts that earn nothing.
Scrap should be told apart from rework, where a part is repaired and sold, and from the yield of a process, which looks at good output compared with input. Scrap is also the quality factor in OEE. To lower it, teams record the reasons for each scrapped part and use methods such as root cause analysis, poka-yoke and standard work. The first step is reliable counting, because many plants underestimate scrap that is thrown away without being logged.
