What is Software Quality Assurance?
Software Quality assurance makes sure the project will be completed based on the previously agreed specifications, standards and functionality required without defects and possible problems. It monitors and tries to improve the development process from the beginning of the project to ensure this. It is oriented to “prevention”.
Software QA is involved in the project from the beginning. This helps the teams communicate and understand the problems and concerns, also gives time to set up the testing environment and configuration. On the other hand, actual testing starts after the test plans are written, reviewed and approved based on the design documentation.
Software quality assurance testing process identifies problems early on in the development process, isolating project risk and maximizing ROI for clients. Verification is preventing mechanism to detect possible failures before the testing begin. It involves reviews, meetings, evaluating documents, plans, code, inspections, specifications etc. Validation occurs after verification and it’s the actual testing to find defects against the functionality or the specifications.
This can include processes such as requirements gathering and documentation, source code control, code review, change management, configuration management, release management and the actual testing of the software. Software QA is often confused with Software Testing, but should not be. These QA methods, in manufacturing, proved themselves to work (in Sales, Customer satisfaction and the right cost of production, i.e. PROFIT) and were adopted all over the world. QA groups (for manufacturing) became the norm.
