Testing should become an integral part of each phase of the Software Development Life Cycle.
Let us define first: what the Quality Assurance is. According to the Cambridge Dictionary, it is the managing of every stage of a production process to make certain that the goods being produced are of the intended standard.
These activities are undertaken to ensure the required level of quality of the manufactured product. In simpler terms, QA includes control over the quality of all organization processes, even those that are not directly related to the product.
QA Vs QC
Also, it’s vital to understand the difference between Quality Assurance and Quality Control. The first one guarantees that the process is delivered correctly and gives a predictable result, while the second ensures that the product meets the specified set of requirements. QA is responsible for activities at all stages of the software life cycle that are undertaken to ensure the required level of quality of the manufactured product. There is one more process – testing. Its goal is to check the correspondence between the actual and expected behavior of the program.
Why Quality Assurance is necessary
Do not skimp on QA! Despite the fact that Quality Assurance may cost 20-30% of developing application costs, it is a very important stage.
Keep in mind that you are releasing a product to a highly competitive market, so you cannot do it willy-nilly. It is better to find bugs before release, so as not to process negative reviews. You may not be given a second chance after an extremely bad experience, even if you fix it. So, better don’t risk.
If a successful launch of a software product is a higher priority for you than a high development speed and economical expenditure of funds, testing should become an integral part of each phase of the Software Development Life Cycle.
