How annoyed you be if you bought a smartphone only to find it doesn't work as expected?
Probably pretty annoyed right?
This is where quality control and quality assurance come into play, ensuring products meet customer expectations.

Quality Control: Identifying and Fixing Defects

Definition

Quality control

Quality control involves inspecting products at various stages of production to identify and fix defects.

How It Works

Inspection Points: Products are checked at critical stages, raw materials, during production, and before shipment.
Defect Identification: Any issues are identified and corrected before the product reaches the customer.
Feedback Loop: Data from inspections is used to improve processes and reduce future defects.

Example

A car manufacturer might inspect vehicles for paint quality, engine performance, and safety features at different stages of assembly.

Benefits of Quality Control

Prevents Defective Products: Ensures only high-quality products reach customers.
Reduces Waste: Identifies issues early, minimizing costly rework or scrap.
