Quality control is a process used by companies to ensure that their products meet certain standards of quality. This involves checking and testing products at various stages of production to identify any defects or issues. By doing this, businesses can maintain customer satisfaction and reduce waste, ultimately saving time and money. In many industries, such as manufacturing and food production, quality control is essential. For example, a food manufacturer might test samples of their snacks to ensure they are safe to eat and taste good. This careful monitoring helps build trust with customers and keeps the brand's reputation strong.
