What is the difference between quality assurance and quality control in software development?

  • Quality assurance ensures that processes are followed to deliver a quality product, while quality control ensures that the product meets specified requirements.
  • Quality assurance focuses on preventing defects, while quality control involves identifying defects after the product is developed.
  • Quality assurance involves testing the final product, while quality control involves testing throughout the development process.
  • Quality assurance is performed by developers, while quality control is performed by testers.
Quality assurance (QA) and quality control (QC) serve distinct but complementary roles in software development. QA focuses on the processes and activities used to develop the product, ensuring that they are effective in delivering a quality product. QC, on the other hand, involves activities such as testing and inspection to identify defects in the product itself. Understanding this distinction is crucial for ensuring overall product quality and process improvement.
