Six Sigma Green Belt Certification Practice Exam

A DMADV approach is used for a product:

1. At the end of its product life

2. Product is not in existence

3. That has been recalled

4. The customer sees no added value in it

The correct answer is: Product is not in existence

The DMADV approach, which stands for Define, Measure, Analyze, Design, and Verify, is specifically used in the context of creating a new product or process rather than improving an existing one. This methodology is part of the Six Sigma framework and is applied when a product or process does not currently exist or when there’s a need to develop a new solution that meets specific customer requirements and quality standards. When a product is not in existence, the DMADV approach allows teams to systematically define what the product should entail, measure relevant market data and customer needs, analyze necessary elements, design a prototype or model, and verify that the product meets the defined standards before full-scale implementation. This approach ensures that new products are developed with a clear focus on customer value and process efficiency, aligning perfectly with Six Sigma principles. In contrast, the other options represent scenarios involving existing products. A product at the end of its life would not require DMADV, as it would be focused on closing or phasing out efforts rather than developing new products. A recalled product is typically in need of improvement or re-engineering, which would align more with the DMAIC (Define, Measure, Analyze, Improve, Control) methodology. Lastly, if a customer sees no added value in
