Quality assurance (QA) is a process or set of processes used to measure and control the quality of products or services. It is a means of providing confidence that quality requirements will be fulfilled. The main goal of quality assurance is to prevent defects from reaching customers or end users. Quality assurance is often confused with quality control (QC), which is a set of processes used to ensure that a product or service meets quality standards. While QC is focused on meeting quality standards, QA is focused on preventing defects.
Quality assurance is important because it provides a method for measuring and controlling the quality of products or services. It helps to ensure that products or services meet customer expectations and requirements. Quality assurance can also help to improve customer satisfaction and loyalty, and to reduce costs.
