MAT 510 WEEK 5 MIDTERM EXAM • Question 1 Lean manufacturing, Six Sigma, Total Quality Management are some of the new systems for managing and improving an organization. What is a common them e running through these approaches? • Question 2 Which of the following are principles of Statistical Thinking? • Question 3 Improvement is needed for an organization to survive because: • Question 4 Process improvement activities typically include: • Question 5 The principal drivers of the rapid change in the global economy are: • 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 It is, unfortunately, common in business for managers to demand an explanation for variation that is, based on statistics, typical and expected variation, i.e., common cause variation. Alternatively, there may be obvious special causes in the data that may be shrugged off as “typical business fluctuations”. Which of the following statements about interpretation of variation are true? • Question 8 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 9 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 10 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? • Question 11 What is tool that can be used to detect the structure variation? • Question 12 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 13 Sub-optimization occurs when: • Question 14 Process measurements are: • Question 15 Viewing a business as a system is important because: • Question 16 The primary goal of process mapping is to: • Question 17 Service and non-manufacturing processes: • Question 18 The SIPOC model for a business helps everyone in the company see the business from an overall perspective by: I. Keeping a focus on customer needs II. Identifying inputs and outputs for each step of the process III. Displaying cross-function activities in simple terms IV. Helping maintain the big business picture • Question 19 Service processes are different from manufacturing processes in that: • Question 20 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? • Question 21 The frameworks discussed in Chapter 4 could be considered more specific examples of: • Question 22 Suppose the Process Improvement Framework were used to attack a problem where the process in question was inherently unstable. Which of the following would be a likely result of this effort? • Question 23 Which type of variation was critical to resolving the realized revenue case study? • Question 24 Which of the following are valid statements about the DMAIC framework? • Question 25 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?
