Hi Gaurav Many people and organizations are confused about the difference between quality assurance (QA) quality control (QC) and testing. They are closely related but they are different concepts. But all these three are useful to manage risks of developing and managing software. * Quality Assurance: A set of activities designed to ensure that the development and/or maintenance process is adequate to ensure a system will meet its objectives. * Quality Control: A set of activities designed to evaluate a developed work product. * Testing: The process of executing a system with the intent of finding defects. (Note that the process of executing a system includes test planning prior to the execution of the test cases.) QA activities ensure that the process is defined and appropriate. Methodology and standards development are examples of QA activities. A QA review would focus on the process elements of a project - e.g. are requirements being defined at the proper level of detail. QC activities focus on finding defects in specific deliverables - e.g. are the defined requirements the right requirements Testing is one example of a QC activity but there are others such as inspections The difference is that QA is process oriented and QC is product oriented. Testing therefore is product oriented and thus is in the QC domain. Testing for quality isn't assuring quality it's controlling it. Quality Assurance makes sure you are doing the right things the right way. Quality Control makes sure the results of what you've done are what you expected. Thanks

Quality assurance is creating or streamlining existing testing techniques/protocols/procedures to create a quality product. Quality assurance will make sure correct and apt quality guidelines and procedures are set for the QC department to test a product. Testing is the act of performing some checks or tests to make sure the product under test adheres to the quality standards and requirements (shape size colors etc).
