Cost of Quality: A Comprehensive Guide

What is Cost of Quality?
Cost of Quality (CoQ) refers to the total costs incurred in maintaining quality in products or services. This includes costs associated with prevention, detection, and rectification of defects. CoQ is a crucial aspect in any business as it allows monitoring and managing of expenses associated with quality controls.

Why is it Important?
Understanding the Cost of Quality is paramount because it allows businesses to measure the financial impact of defects and the direct benefits of improving quality. CoQ assists in identifying areas of waste, inefficiencies and opportunities for improvement. It aids businesses in making strategic decisions regarding quality management.

How Does It Work?
Cost of Quality works by quantifying the total costs associated with the prevention, appraisal, internal failures, and external failures. Prevention costs are spent to avoid defects, appraisal costs are incurred in detecting defects, while internal and external failure costs are due to defects themselves. Reducing these costs means a direct increase in profit margin.
