What is Quality Assurance Concept?

Quality assurance refers to the maintenance of an intended quality level in the products or services, right from the very beginning of the production process or delivery of services.

Quality assurance (QA) is a process of preventing mistakes and defects in manufactured products and avoiding trouble when delivering goods or services to consumers.

Also, ISO 9000 defines as "part of quality management focused on providing confidence that standard requirements will be fulfilled".
