Cost of Quality vs. Cost of Poor Quality: Why the Distinction Matters

In the world of quality management, we often talk about improving processes, reducing risks, and enhancing customer satisfaction. But behind all these efforts lies a critical question: How much does quality truly cost?

Let’s break this into two components:

1. Cost of Quality (CoQ):

This is the investment made to ensure products and services meet customer expectations and compliance standards. It is further divided into:

Prevention Costs: Efforts to avoid defects (e.g., training, process improvement).

Appraisal Costs: Evaluating products/services to confirm quality (e.g., inspections, audits).

2. Cost of Poor Quality (CoPQ):

These are the expenses incurred when quality requirements aren’t met. They include:

Internal Failures: Costs from defects found before delivery (e.g., rework, scrap).

External Failures: Costs from defects found after delivery (e.g., warranty claims, lost customers).

The Key Insight:

While cost of quality is an investment, cost of poor quality is a liability. Many organizations focus solely on minimizing the visible costs of poor quality but overlook the hidden costs, such as reputational damage and lost opportunities.

Why It’s Worth the Investment:

Studies consistently show that prevention is cheaper than correction. A strong quality management system—aligned with ISO 9001 or other frameworks—helps shift resources toward prevention and appraisal, ultimately reducing failure costs.
