Focus on Quality

  • Quality Assurance focuses on the processes used to create the software, making sure everything is done the right way from the beginning.

Preventive vs. Detective

  • Quality Assurance uses a preventive mechanism. It’s about putting the right procedures in place to prevent problems from happening in the first place. It ensures that the development process is smooth and follows standards.

Overlap in Testing

  • Testing is about verifying that the development process (like design and code reviews) is working well and follows the plan.

Complementary Roles

  • Quality Assurance sets up processes to prevent defects.

  • Quality Control finds and fixes any defects that might have slipped through.
