Quality assurance (QA) is a systematic process of determining whether a product or service meets specified requirements. It is a term used in both manufacturing and service industries to describe the systematic efforts taken to assure 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 and delivered services.
The quality assurance process helps a business ensure its products meet the quality standards set by the company or its industry. The QA team is involved in all stages of a product’s development: production, testing, packaging, and delivery. In contrast, quality control (QC) is a narrower process that focuses on detecting mistakes, errors, or missed requirements in a product. The two key differences between QA and QC are that QA is proactive, while QC is reactive.
Quality assurance helps a company create products and services that meet the needs, expectations, and requirements of customers. It yields high-quality product offerings that build trust and loyalty with customers. The standards and procedures defined by a quality assurance program help prevent product defects before they arise. Quality assurance comprises administrative and procedural activities implemented in a quality system so that requirements and goals for a product, service, or activity will be fulfilled.
In summary, quality assurance is a process that ensures that a product or service meets specified requirements and standards. It is a proactive process that helps prevent defects and mistakes in the development and production of products and services. The QA team is involved in all stages of a product’s development, and the process helps companies create high-quality products that meet the needs and expectations of customers.
