What is meant by 'quality assurance'?

'Quality assurance' refers to a systematic approach aimed at ensuring that products and services consistently meet specified requirements. This encompasses a wide range of actions and processes designed to enhance the reliability and quality of a product or service before it reaches the customer. Quality assurance goes beyond just checking or inspecting the final products; it involves proactive measures that are built into the design and development processes to prevent defects and ensure compliance with quality standards.

In contrast, random product sampling, while a tool used in quality assurance, does not encompass the entire framework. It is merely one aspect of the broader quality assurance strategy. Similarly, guaranteeing no defects is not realistic in practical terms, as it implies absolute perfection, which is unachievable; quality assurance focuses on minimizing defects and ensuring a high standard of quality rather than eliminating defects entirely. Finally, while training employees is an essential component of quality assurance, it is only a part of the overarching systematic approach to quality management and not the complete definition itself. Thus, the essence of quality assurance lies in that comprehensive, systematic approach to meeting and maintaining quality standards in products and services.
