Description

Improvement is needed for an organization to survive because: Understanding variation is important because variation: Which of the following are principles of Statistical Thinking? The standard deviation is: Process improvement activities typically include: 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? Box, Hunter, and Hunter are quoted in this chapter as stating: “Data have no meaning in themselves; they are meaningful only in relation to a conceptual model of the phenomenon studied.” This critical point is related to which of the following principles of statistical thinking? 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? Answer 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? Answer In the advertising case study, the unexpected “V” shaped pattern in the plot of advertising dollars versus sales indicated what? Answer 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? What is tool that can be used to detect the structure variation? Answer Service and non-manufacturing processes: The primary goal of process mapping is to: Improving the quality of process measurements is: Refer to Figure 3.21 and choose the correct statement for the measurements We measure, monitor and improve process cycle time because: Processes are important because: Process complexity is important because complex processes: Use of subject matter knowledge is a key aspect of the Statistical Thinking Strategy discussed in Chapter 2. For which of the following case studies in Chapter 4 was this principle NOT clearly applied? 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? 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? Suppose the Problem Solving Framework were used to attack a problem where the process in question was inherently stable. Which of the following would be a likely result of this effort? Suppose a DMAIC Framework were used to attack a problem where the process in question was inherently stable. Which of the following would be a likely result of this effort? Answer Which of the following are accurate statements about the relationship between the Process Improvement Framework (PIF) and the Problem Solving Framework (PSF)? Why is it so difficult for a person or an organization to improve? Answer Understanding variation is important because variation: Answer Which of the following are principles of Statistical Thinking? Answer The principal drivers of the rapid change in the global economy are: Answer The standard deviation is: Answer The Statistical Thinking Strategy has significant commonality with the scientific method. Which of the following statistical thinking principles is NOT generally associated with the scientific method? Answer In the advertising case study, the unexpected “V” shaped pattern in the plot of advertising dollars versus sales indicated what? Answer What is tool that can be used to detect the structure variation? Answer A manufacturing process has been experiencing problems. The operators charting the process data have identified the cause to be due to an unanticipated change in incoming raw materials. This problem should be considered: Answer 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? Answer In the soccer case study, Coach Hau developed a flowchart of the steps one goes through to properly “head” the ball, and then developed unique drills to develop the team’s skills in each of these steps. This approach is an example of what statistical thinking principle? Answer 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? Answer We measure, monitor and improve process cycle time because: Answer Viewing a business as a system is important because: Answer Service and non-manufacturing processes: Answer Process measurements are: Answer Refer to Figure 3.21 and choose the correct statement for the measurements Answer Improving the quality of process measurements is: Answer The Hidden Factory is: Answer The frameworks discussed in Chapter 4 could be considered more specific examples of: Answer 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? Answer Which type of variation was critical to resolving the realized revenue case study? Answer Suppose a DMAIC Framework were used to attack a problem where the process in question was inherently stable. Which of the following would be a likely result of this effort? Answer 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? Answer Which of the following are accurate statements about the relationship between the Process Improvement Framework (PIF) and the Problem Solving Framework (PSF)? Answer
