Quality Assurance Definition

Quality assurance (QA) is the process of preventing product failures. It is an ongoing process throughout the product development cycle that involves identifying and addressing the sources of quality issues before the final product is released to customers. Some commonly used QA methods include system testing, usability testing, and feature testing.

QA is a key component of an effective quality management system. It requires careful planning, execution, documentation, and collaboration between multiple stakeholders (designers, engineers, quality, etc.). The goal is to ensure that the end product is safe, reliable, and meets customer expectations, In turn, companies increase customer satisfaction and decrease costs associated with rework, repairs, or returns.
