There is a simple difference between the both. Quality Assurance means making sure whatever you are doing is doing right way whereas Quality Control is product oriented. Testing for quality doesn't mean assuring quality but controlling it. QC aims to find defects in the finished product and hence is a reactive process whereas QA aims to prevent defects while making the product.

Hi Buddy,

hope you are doing great.

Here are the difference between both:


Quality assurance concentrated on preventing defect. Quality Assurance confirms that the methods, techniques, procedures and practises are designed for the projects are applied appropriately. Quality assurance actions monitor and confirm that the procedures used to manage and create the deliverables have been followed and are operative.

Quality Assurance is a proactive process and is Prevention in nature. It recognizes flaws in the process. Quality Assurance has to complete before Quality Control.

Everyone on the team involved in developing the product is responsible for quality assurance.

QA is a managerial tool


Quality control ensures that the approaches, techniques, methods and processes are designed in the project are following correctly. QC activities monitor and verify that the project deliverables meet the defined quality standards.

Quality Control is a reactive process and is detection in nature. It recognizes the defects. Quality Control has to complete after Quality Assurance.

Examples of quality control activities include inspection, deliverable peer reviews and the testing process.
