Quality assurance encompasses the processes and procedures that systematically monitor different aspects of a service or facility. Through audits and other forms of assessment, quality assurance efforts detect and correct problems or variances that fall outside established standards or requirements. Quality assurance methods focus on establishing good processes to produce products with the quality already built-in, rather than going through an unmonitored production process and trying to “inspect the quality” of a product that’s already been finished.
