How does quality assurance differ from quality control?

Quality Assurance (QA) and Quality Control (QC) are two different approaches to quality management.

• Quality Assurance is a process aimed at preventing defects in the product. It includes planning, standardization of development and testing processes, team training, and audits. QA is responsible for creating conditions under which the product will be of high quality.

• Quality Control is a process of identifying defects in an already created product. QC involves testing, checking, and inspecting the final product to detect errors and non-conformities to requirements.

In simple terms, QA is about processes and error prevention, while QC is about checking and fixing errors in the product.
