QA vs. QC: Understanding the Key Difference

Summary

In this video, Charles explains the difference between QA (Quality Assurance) and QC (Quality Control). QA is proactive, focusing on preventing problems by setting up systems and processes, like following a recipe when baking cookies. QC, on the other hand, is reactive, inspecting the final product to identify defects. Both QA and QC are essential for ensuring high-quality products, with QA handling planning and training, while QC focuses on testing and inspection. The video also recommends exploring courses on quality management for deeper insights.
