What is Difference Between Testing,QA and QC?
Posted By Lax on March 10th, 2009 in Manual Interview Questions
Testing: The process of executing a system with the intent of finding defects including Test planning prior to the execution of the test cases.
Quality Control: A set of activities designed to evaluate a developed working Product.
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.
The key difference to remember is that QA is interested in the process whereas testing and quality control are interested in the product. Having a testing component in your development process demonstrates a higher degree of quality (as in QA).

QA is PROCESS oriented
QC is PRODUCT oriented
EXAMPLE:
Suppose a person is making a tea,then whatever processes are involved in this like boiling the water, adding the tea, adding the sugar. THAT IS ALL COMES UNDER THE qa:
Secondary when the tea is ready means product is ready THAT IS CALLED THE qc.
