QA and QC in daily life,

To understand better, let’s imagine. One day you are assigned to babysit. A baby can’t walk but can only crawl. It takes 5-6 minutes to crawl out of the room as quickly as possible. Therefore, you can choose to return to babysit every 5 minutes. Or you buy a wooden cradle and put the baby in, the baby will not be able to crawl out anymore. It’s all up to you to choose. If you want to watch the baby every 5 minutes then you go in the direction of QC. You want to put a wooden cradle, then you follow the direction of QA.
