Relationships and Overlaps (Quality Assurance and Quality Control)
Focus on Quality
- Quality Assurance
- Quality Control
- Quality Assurance focuses on the processes used to create the software, making sure everything is done the right way from the beginning.
- Quality Control focuses on the finished product, testing it to catch and fix any defects or issues.
Preventive vs. Detective
- Quality Assurance
- Quality Control
- 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.
- Quality Control uses a detective mechanism. It comes after the software is built, focusing on finding and correcting problems that already exist in the product.
Overlap in Testing
- Quality Assurance
- Quality Control
- Testing is about verifying that the development process (like design and code reviews) is working well and follows the plan.
- Testing is about executing the software, finding bugs, and checking if the final product meets the requirements.
