None of the above is true 4. A new machine is available that will decrease the time for step D to 10 minutes. If the firm’s goal is to make the process as short as possible (least time) should the firm consider buying the machine? . Yes, because D is not on the critical path Yes, because D lies on the critical path % , No, because D is not on the critical path /d./ No, because D lies on the critical path 2197c: Wrong {2.6070 ugba-1O Module 4 2 Q Auto-pedestrian accidents have been a serious problem in Oakland; if you were asked to advise the Mayor on policy steps to fix the problem, you would begin by noting that probably: a. 80 percent of accidents are caused by 20 percent of all pedestrians ’ V 80 percent of accidents occur on only 20 percent of the city’s streets 20 percent of the accidents occur on 20 percent of the streets 91? 80 percent of accidents occur on 80 percent of the streets 6. You are constructing a Pareto chart, and note that the category “All Other” is, in fact, the largest group of causes of error. You should: a. Reanalyze the data without the “all other” category /b.‘ Throw out the data, and collect it again Reanalyze the data to group items in “allother” into specific categories . Add the remaining categories into “all other” 7. While you are working on a Total Quality Management project, your manager says: “Well, if nothing else, we should ‘pick the low-hanging fruit’.” In this context the manager means: /a./ Tackle the most serious problems first /h{ Tackle only those problems that are related to equipment breakdowns Fix the problems for which an easy, inexpensive solution is available, even if they are not they are not the cause of the most numerous errors /d./ Fix the problems that relate to personnel 8. Why do we use a fishbone diagram? To group problems logically by groups of causes so they can be assigned to teams of staff for analysis and resolution ' /b./flr To measure the size of each cause of poor quality To group together all the consequences ’of a bad decision /d./ To calculate the Upper and Lower Control Limits (UCL, LCL)? 9. Total Quality Management (TQM) has now been embraced by almost all US firms. Which of the following is true? /' TQM is largelya European invention b. Most TQM initiatives are modeled on Japanese practices @ Most of the techniques used to achieve Total Quality Management were developed in the US before World War II, but were largely ignored d. Quality Management initiatives were largely the result of efforts to increase production in the US in World War II 3 ugba-1O Module 4 10. At times, US factories have tolerated high failure rates for their products because companies subscribed to the View: Consumers won’t pay for high quality @ Since the marginal cost of production of replacement units is small, it’s cheaper to offer a replacement if something fails than to make it right in the first place c. High quality is more or less impossible to achieve in production line systems d. Customers willingly bear the costs of failure as long as the original price paid for goods is low enough. 11. Most American families are quite small, with just one or two children; most have just one washer and drier. Suppose you were living in a large family— say with nine children. You have one washer and one drier and realize you need more laundry caacity, which is true? You should buy a second drier first, because the dry cycle is much longer k than the wash cycle /b./ You should buy a second washer first, because the wash cycle is shorter than the dry cycle c Buying just one appliance won’t help; since all clothes need to be both washed and dried, you must by washers and driers in pairs and you’d need two new appliances d. You cannot solve the problem by outsourcing the laundry function. 12. All modem companies consider “outsourcing” a large number of business processes.

Your company is moving to adopt Just In Time manufacturing; you call a conference of your suppliers and warn them that theywill be required: To send deliveries more often To send smaller quantities in each delivery To send deliveries less often 1 E“. A and B are correct e. B and C are correct 15. 16. 17. 365070 wrong) 18. ugba-1O Module 4 4 We are managing a project using a Gantt chart. Every Monday morning, we have a review a. C. d. meeting and see whether we have achieved certain: Rate limiting steps Milestones Bottlenecks Constraints A factory has dozens of different machine processes, each feeding one into the . other. We are attempting to achieve maximum efficiency (units produced / hour). Under fl: fl, what circumstances would there be no bottleneck? There are no manual steps, everything is done by automated machines _ When we have sufficient warehouse space at the end of the process to accommodate all the production from a shift All of the processes operate at exactly the same rate (units / hour) When there is only one machine that is slower than the others Many call center jobs have been outsourced to India and the Philippines, because: «‘ a. J b. JC. @ The cost of telecommunications is dramatically lower than it was 15 years ago Workers in these countries are prepared to work for lower wages than workers at similar jobs in the US There are many university—trained workers in India All of the above are true ManyUS firms are reluctant to locate offices and facilities in Mississippi and Texas, rwh a. ,/ . g/ at reason, according to lecture? Legal environment unfriendly to business Very low unemployment rates, so there are few workers available No natural resources in these states Poor transportation infrastructure Waits add no value, so Service Operations managers seek to eliminate waits.

Unlike factories, services have to plan for the same amount of production per unit time 21. mpowenng workers requires which essential step, according to lecture? Training front line workers . ”’ Making sure f /nt line workers check their decisions with managers /c’." Instituting a h nus program with cash rewards first Firing one or two workers each quarter to keep everyone “on their toes.” 22. Queuing theory provide service managers with a set of equations that would enable them to predict the effect of all except which one of the following: The average number of people in line The effect of adding more servers / . . . The effect of paying the servers a bonus to manage their hnes better d: The e ected wait time fora ical customer ./ XP 23. Service mana ers ident' each customer’s re uests as “routine” or an “exce tion”, 3 q P I dthen: ' They set up processes to handle “exceptions” in a routine manner /b< ,,,, _, They eliminate exceptions ,zef/ They learn to treat all routines as if they were exceptions and take them off- line < d: As customers who are askin for “exce tions” to read and understand the / g P companys policies before returning 24. The last textbook we used proposed a fifth type of Utility: Infonnation Utility. (The proposition was that customers might prefer Charles Schwab’s website to, say, Ameritrade, if Schwab provided more Information, even though both firms could trade stock.)

A and B are true e. A and C are true 27. You are manufacturing dishwashing liquid, and have a new product that cleans grease from dishes very well. You marketing group comes back to the product development staff and asks if they can’t make the liquid thicker (more viscous).

One of the following does not mean the same as the others. Which is the odd one out? a. Ishikawa diagram V b. Cause and effect diagram @ Pareto chart (1. Fishbone diagram 29. In the 1970s, Japanese car manufacturers such as Toyota, developed a system of manufacturing, based on minimal inventories, called “Just-in—time” GIT). (They got the idea from observing how US super- markets were restocked every night, and how US stores did not have large warehouses attached.) JIT is the opposite of a style of manufacturing preferred by Henry Ford that emphasized control over all the factors of production, including sourcing raw materials within the firm. Which term best fits Henry Ford’s approach? a. Outsourcing No b. Horizontal integration exceptions c. Virtual corporation @ Vertical integration 30.
