What is quality control?

Quality control refers to the processing that ensures the product quality is maintained and upgraded. To do so, the company designed a chain of command that includes the chief operating officer to the end level of employees who ensure the product quality is up to the mark and will satisfy the customer needs; this processing is known as quality control. Since the quality of the product depends on quality control, the organization ensures that quality control processing is error-free by training its employee, which involves several steps to check the product value. For instance, before selling off the furniture, the furniture manufacturing company examines multiple times whether the product is all good to run for decades. It means that the goal of quality control is to testify and correct all the issues with the product before it reaches the end customer.
