Applications and software undergo a lot of testing during development to ensure that they meet the required quality specifications and intended level of performance. Therefore, software quality assurance is the activity of monitoring the quality and improving the software to ensure that they all meet the set standards. SQA uses the system integration testing methodologies to evaluate the software on individual attributes. A successful SQA process allows the software to work efficiently without crashing or hogging the system. Some of the errors that occur during software development may emanate from a design error, wrong coding, handling the data wrongly, or poor functioning.
