Quality Assurance is about Process. It describes the proactive method of establishing a process that is capable of producing a product or deliverable that is error or defect free. Expanding on this further, we can see that:
Quality Control is about Products or Deliverables. It describes checking a final product or deliverable to ensure that it is defect or error free and meets specifications.
To summarize, Quality Assurance is focused on the process, is proactive, and prevents defects; while Quality Control is focused on the product or deliverable, is reactive, and detects defects after the fact.
