What Different between Quality Assurance & Quality Control?

What is the diffference between quality control and quality assurance?

• Answer:

  Clearly, there are marked differences between quality guarantee and quality control. Assurance of quality is a set of preventive activities, which are focused on processes whereas quality control is a detection activity, which is focused on detecting the defects once the product is manufactured. Assurance defines the standards to be followed in order to meet the customer requirements whereas quality control ensures that these defined standards are followed at every step. This is done by conducting various tests and checks. Based on these tests and checks, the quality control prepares regular reports that act as an input to the assurance of quality department which then reviews the same and decides on the corrective and preventive actions required in the processes.
