| Focus on | QA’s goal is to prevent defects with a focus on the processes used to make the product. Therefore, it is a Proactive quality process. | QC’s goal is to identify and correct defects in the final product. Therefore, it is a Reactive process. |
| How | To build a good quality management system and the assessment of its adequacy. Periodic conformance audits [System, Process, and Product audit] of the operations of the system. | Everyone on the team i.e. all functions/departments, are involved in developing the product is responsible for QA. |

| Statistical Techniques | When statistical tools and techniques applied to the finished product [process output], they are called Statistical Quality Control-SQC and comes under QC | When statistical tools and techniques applied to finished product [process output], they are called Statistical Quality Control-SQC and comes under QC |
| Orientation | Quality Assurance is Process-oriented | Quality Control is Product-oriented |
| Example | Verification/Audit is an example of QA | Validation/Software Testing is an example of QC |
