## 1. What does the Taguchi Method primarily focus on in the context of quality control? - [x] Design and development to minimize waste and defects - [ ] Post-production inspection and corrections - [ ] Increasing production speed at any cost - [ ] Random testing of finished products > **Explanation:** The Taguchi Method emphasizes designing products to prevent defects rather than catching them after production. ## 2. Who is the creator of the Taguchi Method? - [x] Genichi Taguchi - [ ] W. Edwards Deming - [ ] Philip Crosby - [ ] Joseph Juran > **Explanation:** Genichi Taguchi is the founder of the method and made significant contributions to quality engineering and statistics. ## 3. Which of these companies has implemented the Taguchi Method? - [ ] McDonald's - [x] Toyota - [ ] Starbucks - [ ] KFC > **Explanation:** Toyota is well-known for applying the Taguchi Method to enhance the quality of its vehicles. ## 4. What is a key feature of the Taguchi Method? - [x] Prevention of manufacturing variances - [ ] Detection of errors post-production - [ ] Judging quality by customer feedback - [ ] Randomized controlled trials > **Explanation:** A core feature of the Taguchi Method is to prevent variances before they can lead to defects. ## 5. Which of these statements best describes "robust design"? - [ ] It only refers to cosmetic changes in a product. - [x] It makes a product less sensitive to variations in the environment. - [ ] It requires extensive testing after the product is made. - [ ] It's just a flashy marketing term. > **Explanation:** Robust design aims for performance stability despite changes in variables affecting the product. ## 6. Which outcome does the Taguchi Method strive for? - [x] High-quality products at a lower cost - [ ] Increased hiring of quality inspectors - [ ] More complex manufacturing processes - [ ] Guaranteed perfection with no testing > **Explanation:** The method aims for high-quality production efficiency, leading to cost savings without depending solely on inspection. ## 7. Which industry is particularly known for adopting the Taguchi Method effectively? - [x] Automotive - [ ] Retail - [ ] Entertainment - [ ] Hospitality > **Explanation:** The automotive industry, particularly Toyota, has greatly benefited from implementing the Taguchi Method. ## 8. What is the advantage of focusing on quality by design in the Taguchi Method? - [ ] It ensures timeless products - [ ] It makes marketing easier - [x] It reduces the costs of production errors - [ ] It increases the complexity of the production process > **Explanation:** By focusing on quality by design, overall production costs are reduced due to fewer defects. ## 9. The Taguchi Method mainly utilizes what type of approach to eliminate defects? - [ ] Reactive - [x] Preventative - [ ] Experimental - [ ] Budget > **Explanation:** The Taguchi Method is preventative as it works at the design stage to eliminate the potential for defects before production starts. ## 10. Which of the following reflects a property of robust design? - [ ] It always makes things more complicated. - [x] It focuses on reliability under conditions of variation. - [ ] It guarantees absolutely no defects will occur. - [ ] It requires a large number of detailed documents. > **Explanation:** Robust design ensures that products work reliably despite environmental and operational variations.
