Question 5

Process average or mean:                          

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

In the advertising case study, the unexpected “V” shaped pattern in the plot of advertising dollars versus sales indicated what?                                 

Question 8

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 9

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?                                  

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

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 12

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?                                  

Question 13

Process measurements are:                        

Question 14

Sub-optimization occurs when:                            

Question 15

Service processes are different from manufacturing processes in that:                                 

Question 16

Viewing a business as a system is important because:                         

Question 17

We measure, monitor and improve process cycle time because:                                

Question 18

Service and non-manufacturing processes:                                

Question 19

Process complexity is important because complex processes:

Question 20

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 21

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 22

Which type of variation was critical to resolving the realized revenue case study?                                   

Question 23

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 24

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?                               

Question 25

If you are thinking creatively about how to take existing tools and link and sequence them to develop a novel approach to solve important problems, this would be an example of:
