Question 1 Among the guiding principles of six sigma are: (I) Reduction of variation is an important goal. (II) Valid measurement is critical. (III) Outputs determine inputs. (IV) (IV) We should ... focus on those critical few influences on our quality. Question 2 Which of the following raises quality risks? Question 3 Deciding how much to invest in the prevention of defects can be analyzed using: Question 4 The tool that is useful in documenting the current process is a: Question 5 The quality tool which helps focus on the most important problem areas based on the 80-20 rule is: Question 6 A design engineer wants to construct a sample mean chart for controlling the service life of a halogen headlamp his company produces. He knows from numerous previous samples that when this service life is in control it is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. On three recent production batches, he tested service life on random samples of four headlamps, with these results: Sample Service Life (hours) 1 495 500 505 500 2 525 515 505 515 3 470 480 460 470 ________________________________________ What is the mean of the sampling distribution of sample means when the service life is in control? Question 7 The amount of inspection needed depends on __________ and __________. Question 8 Statistical process control charts are not really used to fix quality so much as they are used to: Question 9 A control chart used to monitor the fraction of defectives generated by a process is the: Question 10 The specifications for a product are 6 mm ± 0.1 mm. The process is known to operate at a mean of 6.05 with a standard deviation of 0.01 mm. What is the Cpk for this process? Question 11 Which of the following are typically in play in a circumstance in which yield management is worthwhile? 1. (I) Perishable capacity 2. (II) Ample finished goods storage 3. (III) Demand variability 4. (IV) Low holding costs Question 12 Information for firm ABC: Inventory at the end of April, 2008: 200 units Expected demand during April, 2008: 50 units Production expected during April, 2008: 100 units ________________________________________ What is the expected inventory at the end of April 2008? Question 13 Essentially, the output of aggregate planning is the: Question 14 Simulation to produce an aggregate plan: Question 15 A firm has 43 units of a certain product on hand. Forecasts for the first two planning periods are 20 units each. A production quantity of 80 units is planned to be available in period 3. Customer orders are 22 for period 1 and 17 for period 2. What quantity is available for commitment to new customers in either of the first two periods? Question 16 Which of the following represents an attempt to balance the benefits of stability in the production plan against the benefits of responding quickly to new orders? Question 17 Bunny Helpers, Inc., has just received an order for 100 Deluxe Easter Baskets, which must be ready for delivery at the start of week 6. An MRP planner has prepared the following table showing product structure, lead times (orders are lot-for-lot), and quantities on hand: Deluxe Easter Basket BOM Lead Time On-Hand Deluxe Easter Basket 1 week 10 Dark Chocolate Truffles (2 per) 2 weeks 30 Carved Chocolate Eggs (4 per) 1 week 50 ________________________________________ Each Deluxe Basket contains two dark chocolate truffles and four carved chocolate eggs. When should an order for carved chocolate eggs be released? Question 18 Which of these items would be most likely to have dependent demand? Question 19 In MRP, the gross requirements of a given component part are calculated directly from: Question 20 In many organizations, information flows much more freely within functions than it does across functions. __________ represents an expanded effort to overcome this tendency. Question 21 The PDSA cycle forms the conceptual basis for continuous improvement. Question 22 An x-bar control chart can only be valid if the underlying population it measures is a normal distribution. Question 23 Ultimately the overriding factor in choosing a strategy in aggregate planning is overall cost. Question 24 One reason that accurate bills of material are important is that errors at one level become magnified at lower levels because of the multiplication process used by MRP. Question 25 The inventory records contain information on the status of each item by time period. [Show More]
