[Information] Points to Note in Quality Control - Revision Work Edition (Free Download Available)

Isn't it possible that something that shouldn't have defects actually does? I will introduce and explain a specific example.

In the factory, various products are produced, and the "work instruction sheet," which outlines the work processes in order, is used in situations such as the following: - As educational material when a new person joins and needs to perform tasks - To ensure that there are no omissions when an order comes in after a long time - To clarify changes and prevent incorrect work from being done It is also used when experienced workers confirm familiar work procedures, but I believe its significance is particularly great during what are referred to as the 3 Hs (first time, changes, long time). While the "work instruction sheet" may describe what to do when work proceeds smoothly, there are likely few that include details on how to handle defective products, such as "if a defect occurs in this process, handle it this way." Even if such information exists, does it align with the actual processes? In this document, I would like to introduce cases where "defects occur even though we are supposed to be following the work instruction sheet."
