Quality control during the product development and design phase is called quality design. In manufacturing, it is necessary to monitor the production process, which is called the quality monitoring stage. Controlling quality through sampling inspection is a traditional quality control method, known as post quality control. The most important stage in the above mentioned stages is quality design, followed by quality monitoring, and then post quality control. For production processes with lower quality levels, post inspection is essential, but quality control should be the source control, and the earlier the prevention, the better
