What is different between quality control and quality assurance?

There’s a very fine line between quality assurance and quality control, and both these terms are often used interchangeably.

Quality assurance is the concept stating that the necessary actions, procedures, inspections, and audits will be done or have been done in a particular project to assure the quality of it.

Quality control, on the other hand, is the very act of carrying out all the necessary procedures and seeing to it that all parts of the project are carried out in the absolute correct way restricting the loss of quality. It may include inspection, maintenance, and audits.

I make it simple for you,

Quality control and quality assurance are the two terms that may be interchangeably used. But there are some differences between these two concepts.

quality control is a subpart of quality assurance.

Quality Assurance:

The assurance given by the engineer or builder for various projects for the quality of materials is called quality assurance. Basically, it is the plan that fulfills all the requirements of the project and the quality of the project.

Quality control: it is a control measure for various materials or may be described for the project to fulfill various requirements. It is the technique to fulfill the quality requirements.

Hope you get the difference.
