Testing and Quality Assurance

What is the relationship between testing and Software Quality Assurance (SQA)?

An application that meets its requirements totally can be said to exhibit quality. Quality is not based on a subjective assessment but rather on a clearly demonstrable, and measurable, basis. Quality Assurance and Quality Control are not the same.

Quality Control is a process directed at validating that a specific deliverable meets standards, is error free, and is the best deliverable that can be produced. It is a responsibility internal to the team. QA, on the other hand, is a review with a goal of improving the process as well as the deliverable.

QA is often an external process. QA is an effective approach to producing a high quality product. One aspect is the process of objectively reviewing project deliverables and the processes that produce them (including testing), to identify defects, and then making recommendations for improvement based on the reviews.

The end result is the assurance that the system and application is of high quality, and that the process is working. The achievement of quality goals is well within reach when organizational strategies are used in the testing process. From the client's perspective, an application's quality is high if it meets their expectations
