COQ is like the unseen superhero behind the scenes, guaranteeing that your purchases are worth every cent and fulfill your and other customers’ requirements. It’s all about delivering quality with a capital Q!

Cost of Quality (COQ) has divided into four main parts – 

  1. Prevention Costs
  2. Appraisal Costs
  3. Internal Failure Costs
  4. External Failure Costs


1. Prevention Costs

These are the costs you put in place to prevent issues from cropping up in the first place. Imagine it as the superhero cape that prevents problems from showing up. These costs are all about stopping defects and issues before they happen. The following things fall under this category.

  • Training employees
  • Improving processes
  • Creating detailed product specifications


2. Appraisal Costs

This is where “Testing” comes in! Appraisal costs are all about checking the quality of the product. It’s like giving the goods a full checkup to make sure it meets the standards. Inspections, tests, quality audits – these are all part of the appraisal costs gang. So, when you see a product being tested rigorously before it’s packed and sent out, that’s because of appraisal costs.


3. Internal Failure Costs

This occurs when things don’t work out as expected. These are the costs that happen when a defect is discovered before the product reaches the customer. It’s like catching a mistake early on, fixing it, and making sure the customer never even knows about it. These costs include rework, scrap, and all the behind-the-scenes efforts to resolve the situation.


4. External Failure Costs

This is the not-so-pleasant part. These costs happen when the defect is found after the product is out there in the world. Think of it as a product hiccup that reaches the customer. Not great, right? This category includes things like warranties, recalls, customer complaints – all the things we want to avoid but sometimes have to deal with.
