Every product that has a cost to it has to pass through a quality test. Quality is of utmost importance, be it an electronic product, a piece of jewellery , a locomotive or a software product, quality forms an integral part in the process of their deployment. Quality is an aim to assure that a product delivers as expected.
Quality assurance, control and testing activities have a common vision, but indulging on different missions. Consumer satisfaction is the ultimate goal of any business, whatever is being produced is meant for use by someone.

The attribute 'Quality' may be achieved by implementing and following three standard and established procedures, namely; Quality Assurance, Quality Control, Testing.
Quality assurance refers to the activities that take place during the development of a software product. It is the process of verifying whether the expected results are delivered by the product under review. It ensures that the product development adheres to specified standards, techniques and processes.
It is the process of reviewing the actual product. Quality Control intends to identify defects if any, in the deployed product for the purpose of timely rectification.
It encompasses various tasks and approaches to identify and discover bugs/defects in a software product.
