Differences between Quality Assurance and Quality Control

Quality Assurance:
Quality assurance is a method of making the software application with less defects and mistakes when it is finally released to the end users.
Quality Assurance is defined as an activity that ensures the approaches, techniques, methods and processes designed for the projects are implemented correctly. It recognizes defects in the process. Quality Assurance is completed before Quality Control.

Quality Control:
Quality Control is a software engineering process that is used to ensure that the approaches, techniques, methods and processes are designed in the project are following correctly. Quality control activities operate and verify that the application meet the defined quality standards.

It focuses on examination of the quality of the end products and the final outcome rather than focusing on the processes used to create a product.
