Quality Control is the process of ensuring products meet defined standards. It focuses on preventing defects rather than just finding them.

The key steps are:

1. Set Standards: Define clear, measurable specifications for what makes a product pass or fail.
2. Inspect: Check products at three critical stages:
   • Incoming Inspection: Examine raw materials and components.
   • In-Process Inspection: Monitor production for real-time correction.
   • Final Inspection: Verify finished goods before shipment.
3. Test: Perform functional, safety, and durability tests.
4. Record & Analyze: Document findings to identify trends and root causes of defects.
5. Act: Remove defective items and implement corrective actions to prevent future issues.

The goal is to consistently deliver high-quality products to customers through a continuous cycle of checking and improving.
