What is quality assurance in manufacturing?

In manufacturing, quality assurance (QA) is a systematic process aimed at guaranteeing that a company’s goods meet specified requirements and fulfill customer expectations. Product quality is not only dependent on good manufacturing processes that produce defect-free goods. It is also about high-quality materials, timely supply chain movements, well-organized facilities, well-trained staff, and other business aspects that together work toward achieving and maintaining consistent customer satisfaction.

The QA process is a set of practices that a company implements and follows to ensure consistently high product quality. It’s a proactive component of quality management, focused not only on products but also on fulfilling quality requirements. Defining and implementing processes, training teams, or choosing the right tools to yield quality products all fall under it. QA comprises one part of the larger quality management process with the other being quality control.

Quality assurance vs. quality control

Quality assurance and quality control (QC) are often intertwined yet distinctly different aspects of quality management. QA encompasses a broad spectrum of the quality system, focusing on providing confidence that quality requirements will be met. This confidence extends internally to management and externally to customers and regulatory bodies.

In contrast, quality control is more about fulfilling quality standards as set forth by QA. QC, then, can be seen as a more practical subset of quality management that focuses on the operational techniques and activities used to fulfill quality requirements. In other words, QC comprises the practices that ensure that processes follow QA measures. In manufacturing, quality control mostly revolves around inspection and following steps in the manufacturing process that test product quality.

What is quality management?

In manufacturing, quality management is the systematic process of designing a company’s QA processes as well as managing its quality control efforts. It is focused on implementing quality and compliance-related processes and managing quality systems.

Therefore, quality management integrates QA and QC into a single quality management system (QMS). Quality management is about adhering to standards but also ensuring that all stages of design, development, manufacturing, and delivery meet the standards. As outlined above, quality management is crucial in safeguarding not just the finished products but also the quality of raw materials and components involved in the process.

Quality management systems

In modern manufacturing, all the various quality-related activities are brought together into a unified quality management system. Quality management systems (QMS) are formal frameworks that guide manufacturing companies in achieving and maintaining desired quality standards. These systems encompass a wide range of activities, including planning, assurance, control, and improvement of quality. By integrating a quality management system, manufacturers ensure consistency, efficiency, and continual improvement in their production processes.

A QMS often involves the implementation of internationally recognized quality standards. These are made available by accreditation organizations, most notably the International Organization for Standardization, or ISO. For manufacturers, the ISO 9000 series of standards are among the most instrumental quality-oriented standards. Running as the root of a well-implemented QMS, ISO 9000 is instrumental in aligning the quality objectives of a company with its operational processes and regulatory requirements.
