4. Answer Key & Explanations
| # | Correct Answer | Explanation |
|---|---|---|
| 1 | B | Six Sigma targets 3.4 defects per million opportunities (DPMO), a statistical benchmark. Which means |
| 2 | C | Bill Smith at Motorola introduced Six Sigma in the 1980s. |
| 3 | False | Correct sequence: Design, Measure, Analyze, Improve, Control. |
| 4 | B | Flowcharts map the step‑by‑step flow of a process. |
| 5 | C | Control charts detect shifts or trends in a stable process. In practice, |
| 6 | B | An opportunity is any chance for a defect to occur. So |
| 7 | B | Pareto charts rank causes by frequency, highlighting the “vital few. Think about it: ” |
| 8 | B | 5‑Whys iteratively asks “why? Worth adding: ” until the root cause surfaces. Because of that, |
| 9 | B | The mean (average) summarizes a set of numbers. |
| 10 | C | Yellow Belts support projects, often executing small, quick wins. |
| 11 | D | Master Black Belts have the deepest expertise and lead strategic initiatives. Plus, |
| 12 | B | Yellow Belts are typically frontline employees with process knowledge. But |
| 13 | B | A charter defines scope, goals, stakeholders, and success metrics. |
| 14 | B | Engaged stakeholders secure resources and reduce resistance. Day to day, |
| 15 | B | Projects with high cost savings justify the investment in improvement. This leads to |
| 16 | A | Kaizen is the Japanese philosophy of continuous, incremental improvement. |
| 17 | True | PDCA is a cyclical model for systematic problem solving. Plus, |
| 18 | B | Lean targets the elimination of waste (non‑value‑added activities). |
| 19 | D | Perfection refers to a state of no defects—an ideal, not a waste. |
| 20 | C | Over‑design is not listed among the traditional Seven Wastes of Lean. |
