MCT COQ approach

1. Joseph Juran classifies the costs attributable to poor quality into the following categories:

• Failures
• Internal failures
• External failures
• Quality measurement
• Prevention

2. Controlling the costs of obtaining quality allows us, among other things, to:

• Identify and eliminate waste
• Stimulate the continual improvement process
• Set priorities knowingly
• Achieve unsuspected savings
• Search the culprit for the costs

3. Step 3 "Data analysis" of the COQ approach includes:

• The 5 S method
• Seeking the optimum of the COQ
• Classifying the costs by priority
• Updating the indicators

4. The costs of nonconformities over the life of the product cost us the most at stage:

• Design
• Development
• Industrialization
• Production and after sales service

5. The conditions for obtaining the success of the COQ approach include:

• Successful internal communication
• Cost reduction
• Price drop
• COQ procedure applied
• COQ objectives are set
• COQ indicators are measured and followed
