What is the difference between Quality Assurance and Quality Control? Quality Assurance prevents defects in a product, so it is a proactive quality process. Quality Control detects and corrects defects in an already finished product, so it is a reactive quality process.


Quality Assurance and Quality Control are vital for structures and components that can develop flaws, defects, and cracks that will negatively affect performance. Nondestructive testing is frequently used in both Quality Assurance and Quality Control.
