Quality assurance typically involves a range of activities, including requirements analysis, planning and design, testing, and post-deployment monitoring. The QA process may involve both manual and automated testing methods, and may involve the use of testing tools and frameworks.
QA is an important part of the development lifecycle. It helps to identify and resolve defects early in the process, before they reach the user. This helps to ensure that the software meets the needs of the stakeholders and is delivered on time, within budget, and to the desired quality level.
