Chapter 9: Tools for Process Management TRUE OR FALSE 1. Taguchi opposes the use of statistically planned experiments for parameter design. 2. Genichi Taguchi was the originator of experimental design techniques. 3. Controllable and uncontrollable factors are incorporated into the signal to noise ratio. 4. In most industrial processes, the average value is more difficult to control than the variability. 5. The Taguchi Loss Function measures monetary loss as a linear function of the deviation between a product measurement and nominal. 6. According to Taguchi, any deviation from nominal represents a monetary loss. 7. The signal to noise ratio is equal to the reciprocal of the process standard deviation. 8. Taguchi’s approach to experimental design has been criticized for its failure to incorporate some traditional statistical principles. 9. A robust product design is sensitive to external sources of variation to allow the product to satisfy customers in a single market segment. 10. Quality function deployment originated in 1972 as a result of a partnership between Ford, Chrysler, and General Motors.

11. Rework costs would be included as a loss to society under the Taguchi method.

12. The voice of the designer is the primary input to the quality function deployment process. 13. The relationship matrix in QFD shows whether the final technical requirements adequately address the customer requirements. 14. QFD is a customer-driven planning process that guides the design, manufacturing, and marketing of products. 15. An important benefit of QFD is the reduction in product development time. 16. Source inspection in Zero Defect Quality Control focuses on finding defective products after they are produced. 17. The idea behind poka-yoke is to fail-safe a process. 18. Poka-yoke techniques are not applicable to services. 19. According to Juran, money is the preferred language of top management. 20. Crosby recommends establishing an ad hoc committee to communicate and promote the motivational objectives of a zero defects program. 21. The Deming cycle is the basis of most Japanese quality improvement efforts. 22. A histogram provides a graphical representation of the correlation between two variables. 23. Cause-and-effect diagrams are also known as ‘fishbone’ diagrams.

24. Criticism of proposed ideas is actively sought during a brainstorming session. 25. A control chart identifies the root cause of a problem. 26. Poor quality costs do not depend on the actual value of the quality characteristic, as long as it is within the tolerance specified. 27. The loss function for ‘larger is better’ quality characteristics is L(x) = k(1/x 2 ). 28. A challenge of product development is translating customer needs and desires into the company’s technical language. 29. A textbook that is ‘easy to read’ is an example of a technical requirement.
