Quality Assurance (QA) is a framework by which product and service quality is ensured by using a systematic approach.
Quality is a complex concept that can vary significantly depending on the industry, company, or context. Each industry and company define quality based on their specific needs, regulatory requirements, and customer expectations.
Quality in a company is ensured through a system that integrates various processes and procedures. Companies often implement multiple interconnected systems rather than relying on a single standalone approach.
These systems encompass quality assurance, Quality Control (QC), and Quality Management Systems (QMS). While QA, QC, and QMS each have their distinct functions in helping ensure quality, they are interconnected and overlap throughout the product or service lifecycle.
Therefore, a quality assurance system is a system that organizes and integrates all the policies, processes, procedures, and resources necessary to implement and maintain quality assurance activities within a company.
QA systems are implemented across various industries, such as aerospace, finance, and life sciences, covering laboratories, pharmaceuticals, and medical devices.
Various approaches to QA are utilized, including process quality assurance, regulatory compliance quality assurance, product quality assurance, and supplier quality assurance. The QA approach a company implements depends on its industry and compliance needs.
It is important to differentiate quality assurance from quality control because they encompass distinct roles in ensuring the quality of products or services. The main difference between QA and QC is that QA focuses on ensuring that products and services meet the quality specifications, while QC involves controlling and testing to confirm the presence of quality.
QA systems require extensive documentation, which is efficiently managed through QMS software. QMS software automates various QA processes, simplifies document and data management, and reduces errors.

What Is a Quality Assurance (QA) System?
A Quality Assurance (QA) system is a system supported by policies, processes, procedures, and resources that ensure products and services meet or exceed the quality specifications of the company. The QA system ensures the quality, reliability, and efficiency of products and services throughout their lifecycle.
Companies often implement multiple interconnected systems instead of relying on a single standalone solution. These systems include quality assurance, quality control, and quality management system. While QA, QC, and QMS have different functions in ensuring quality, they are interconnected and overlap throughout the lifecycle of products and services.
QC is included in QA, which itself is part of QMS, ensuring comprehensive quality management throughout operations.
The illustration below represents the relation between QC, QA, and QMS.
What Is the History of Quality Assurance?
Quality assurance dates back to the early 20th century when processes started to be recognized as a part of quality. QA gained importance with the introduction of process control methods by pioneers like Walter A. Shewhart, W. Edwards Deming, and Joseph M. Juran.
The Plan-Do-Study-Act (PDSA) tool, also known as the Deming Cycle or Shewhart Cycle, exemplifies this approach. The PDSA provides a structured method in a systematic series of steps used for the continuous improvement of a product or process.
During World War II, the USA introduced sampling inspection to manage the high production volumes of military equipment. With the help of industry experts, the USA published sampling tables to clarify supplier expectations.
After the war, QA gained momentum during Japan’s reconstruction. Prioritizing product quality over costs led to superior Japanese products. Japanese products were manufactured using the Lean management approach. Lean management was developed in Japan at Toyota to optimize production efficiency and minimize waste.
In response, the Total Quality Management (TQM) approach was developed, which integrated statistical methods and total employee involvement. Further quality improvements followed, including the release of the ISO 9000 quality standard in 1987 and the establishment of the Baldridge National Quality Program in the USA that same year.
Quality assurance has evolved significantly over the years, becoming a cornerstone of the quality management system across various industries, including healthcare, manufacturing, finance, life sciences, and other industries.
