1. What is Cost of Quality (COQ) Analysis?

Cost of Quality (COQ) Analysis is a structured method to measure how much your organisation is spending because of poor quality — and how much it spends to prevent it.

It divides quality-related costs into four categories:

Prevention Costs – Training, process control, quality planning
Appraisal Costs – Inspection, testing, audits
Internal Failure Costs – Rework, scrap, defects before delivery
External Failure Costs – Warranty claims, returns, customer complaints

In simple terms, COQ Analysis answers:

How much profit are we losing due to poor quality?
And how much can we save by improving processes?

2. How COQ Analysis Helps Your Organisation

Cost of Quality Analysis improves:

Profit margins by reducing rework and warranty costs
Operational efficiency through process standardisation
Customer satisfaction and retention
Brand reputation
Cost visibility in quality management
Decision-making regarding quality investments

It shifts focus from “detecting defects” to “preventing defects.”

Well-managed quality systems reduce total cost and increase long-term profitability.

3. Who Should Opt for COQ Analysis?

This service is ideal for:

Manufacturing companies facing high rejection or scrap rates
Businesses with frequent customer complaints
Companies offering warranty or guarantee support
Process-driven industries (automobile, pharma, FMCG, engineering)
Service organisations with high rework or error correction cost
Businesses aiming for ISO or quality certification

If your quality-related costs are rising but not clearly measured, COQ Analysis is highly relevant.

4. Frequently Asked Questions (FAQs)

What is the objective of COQ Analysis?

To measure and reduce the total cost associated with poor quality.

Is COQ Analysis only for manufacturing companies?

No. Service organisations also incur quality costs in the form of rework, delays and client dissatisfaction.

Does improving quality increase cost?

Not necessarily. Increasing prevention cost often reduces costly failures and improves overall profitability.

How long does a COQ Analysis project take?

Typically 4 to 8 weeks depending on data availability and process complexity.

What results can be expected?

Lower defect rates, reduced rework cost, improved margins and stronger customer trust.
