1. A job with a 70 percent learning curve required 20 hours for the tenth unit. The twentieth unit should require approximately how many hours, if we consider a learning curve of 70%?
2. Once you have defined the problem in a convincing statement, with facts regarding the problem and its impact on the organization, you proceed to collect data needed to identify the possible root cause. Which of the following is a tool that you will use at this stage of the problem solving process?
3.A radar monitoring job with a 70 percent learning curve required 20 hours for the initial unit. The fourth unit should require approximately how many hours?
4. After Defining the quality problem and collecting the appropriate data needed to identify the possible root cause, you are now ready to begin the Analysis of the problem. Here, you need to identify the specific issues that you can address. In order to do this, you need a quality tool that will help you identify a few of the areas that are causing most of your issues. Identify the tool that will help you do this
5.The number of runs with respect to the sample median is (assume median is 12.5). Observation/# of defects follow: Observation 1 had 10 defects, Observation 2 had 18 defects, Observation 3 had 13 defects, Observation 4 had 15 defects, Observation 5 had 9 defects, and Observation 6 had 12 defects. Answer A) 3 B) 4 C) 5 D) 6 None of these
6.At this point in your problem solving process you have defined the problem, collected and analyzed data. It is time now to identify the possible root causes of the problem and to do this, you will use the following tools needed to identify all the possible root causes
7. The type of process that is used for complex jobs with unique sets of activities, in a limited timeframe is:
8.You are assigned by executives to solve a quality problem and you start by defining the problem. Which of the following items must be part of your problem definition?
9. If you were interested in seeing how data is distributed once you ve collected and organized it, you would use which of the following quality tools?
10. Which area of an organization has no responsibility for quality?
11. Once production is underway and the learning curve effect is occurring, successive changes made to the production process will cause the time per unit to:
12. Using the Learning Curve of 85%, determine what is the expected time required to produce the 40th unit, if we know that the 10th unit took 6.1 hours?
13.A company is preparing a bid on a private contract for 50 projects of software applications. The operations manager of the bidding company estimates the project time required for the third and sixth projects to be 150 hours and 112.5 hours respectively. Using this information and the Learning Curve Rule, determine the appropriate learning curve?
14. The Chair of the Operations Management Department at Quality University wants to construct a control chart for determining whether the four instructors teaching the basic OM course are under control with regard to the number of students who fail the course. Accordingly, he sampled 100 final grades from last year for each instructor, with the following results. From this sample, an average of 10 students failed the course. What are the 2 sigma upper and lower control limits for the chart?
15.What is the appropriate Cycle Time for eight hours of operating time per day and a desired output rate of 960 units per day?
