Which quality management tool displays connections between customer needs and various product features?

1. Parameter (P) Diagram

2. Quality Function Deployment

3. Cause and effect Diagram

4. Relationship Matrix

The correct answer is: Quality Function Deployment

The correct choice is Quality Function Deployment, commonly referred to as QFD. This tool is specifically designed to translate customer needs, or "whats," into engineering characteristics, or "hows," for a product or service. QFD helps in identifying the relationships between what customers desire and the necessary features that will fulfill those desires. By organizing and prioritizing these connections visually, QFD assists teams in ensuring that the final product aligns closely with customer expectations. It enhances communication among stakeholders by clearly presenting how technical attributes correlate with customer requirements, leading to design optimization and increased customer satisfaction. While the other options may serve different purposes in quality management, they do not specifically focus on the relationship between customer needs and product features in the way that QFD does. For instance, a Parameter Diagram may outline specifications, but it wouldn’t inherently connect these with customer desires as effectively as QFD does.
