What does one hundred percent inspection entail?

One hundred percent inspection refers specifically to the practice of checking every single part or unit produced to determine whether it meets quality standards. This process ensures that each item is examined for defects before it reaches the customer.

The rationale behind this approach is that it aims to identify any defective items, allowing for either their repair or removal from the production line to maintain quality. While the practice promises to eliminate defective products from reaching customers, it does not guarantee that only good parts are shipped since it depends on the effectiveness of the inspection process itself.

Therefore, the correct answer emphasizes that every part is individually assessed for defects, which underlines the thoroughness and potential rigor of the inspection process, even if some defective items may still escape detection due to human error or limitations in the inspection method.
