MAT 510 Midterm week 5 • Question 1 W. E. Deming commented “You don’t have to make these changes, survival is not mandatory.” His message is: • Question 2 I... mprovement is needed for an organization to survive because: • Question 3 The principal drivers of the rapid change in the global economy are: • Question 4 A SIPOC map is: • Question 5 Process improvement activities typically include: • Question 6 The Statistical Thinking Strategy illustrated in Figure 2.14 provides a graphic of the overall approach to driving improvement through statistical thinking. Which of the following is a key principle illustrated in this specific graph? • Question 7 Figure 2.16 shows a chart of the Dow Jones Industrial Average from 1990 through 2011. This plot reveals some obvious change points, such as the 2008 financial collapse, and some unexplainable short-term variation. Assuming that these are the only sources of variation in this plot, what source of variation is NOT visible in the plot? • Question 8 Figure 2.15 displays a model of the statistics discipline, showing the relationship between statistical thinking, statistical engineering, and statistical methods and tools. Which of the following is a principle illustrated by this model? • Question 9 The fact that processes tend to be dynamic, rather than static, is a key principle of statistical thinking. Which of the following is a natural consequence of this fact? • Question 10 In Figure 2.11, Coach Hau presented data showing where goals were scored on crosses. This produced unexpected results, in terms of where the goals came from, and helped his team determine an effective strategy on free kicks. This is an example of what principle of statistical thinking? • Question 11 Analysts have noticed that October tends to be a bad month in the collections department – our collections on past due accounts tend to be consistently lower in October. This issue should be considered: • Question 12 In the advertising case study, the unexpected “V” shaped pattern in the plot of advertising dollars versus sales indicated what? • Question 13 The primary goal of process mapping is to: • Question 14 Process complexity is important because complex processes: • Question 15 Improving the quality of process measurements is: • Question 16 Viewing a business as a system is important because: • Question 17 Service and non-manufacturing processes: • Question 18 Refer to Figure 3.21 and choose the correct statement for the measurements • Question 19 Sub-optimization occurs when: • Question 20 We learned in Chapter 3 that the measurement process is always important and worthy of our attention. However, in Chapter 4 we found that measurement can be absolutely critical to solving the problem. For which of the case studies in Chapter 4 was measurement NOT discussed as a critical issue? • Question 21 The Problem Solving Framework begins with a “Document the Problem” phase. The Process Improvement Framework does not begin this way, but rather begins with an “Understand the Process phase.” Which of the following are valid reasons for this difference? • Question 22 We learned in Chapter 2 that most processes are dynamic in nature, and therefore the time dimension is often a critical consideration in process improvement. For which of the case studies in Chapter 4 was plotting data over time NOT critical to success? • Question 23 The frameworks discussed in Chapter 4 could be considered more specific examples of: • Question 24 Which of the following are valid statements about the DMAIC framework? • Question 25 Which of the following are accurate statements about the relationship between the Process Improvement Framework (PIF) and the Problem Solving Framework (PSF)?
