A Quality Assurance Specialist checks the implementation of the quality system and conducts quality assurance audits. He or she creates and implements well defined standards, procedures and methods that reduce variation to ensure a repeatable result within the manufacturing process. The goal is to produce a finished product that meets all industry standards, ideally without testing or inspection.
Quality assurance (QA) is the term used in both manufacturing and service industries to describe the systematic efforts taken to ensure that the product(s) delivered to customer(s) meet with the contractual and other agreed upon performance, design, reliability, and maintainability expectations of that customer. The core purpose of Quality Assurance is to prevent mistakes and defects in the development and production of both manufactured products, such as automobiles and shoes, and delivered services, such as automotive repair and athletic shoe design.
