What is quality control?

Quality Control (QC) is the process of inspecting and evaluating a product or service to ensure it meets established standards and requirements.

Key aspects of quality control:

• Defect detection: Identifying errors, non-conformities, or deviations from expected behavior in a product or service.
• Conformance verification: Ensuring that the product complies with specifications, user requirements, and regulatory documents.
• Defect prevention: Using feedback from quality control to improve development processes and prevent similar defects in the future.
• Tools and techniques: Applying various testing methods (manual, automated), inspections, reviews, and statistical process control.

Quality control is part of a broader discipline — quality assurance (QA), which focuses on preventing defects at all stages of the development lifecycle. While QA aims to improve processes, QC is focused on inspecting the final product.
