Explain. |Time |0 |1 |2 |3 |4 |5 | |Cash Flow |-$100 |-$50 |$80 |$0 |$100 |$100 | They’re normal: there is only one change in cash flows from negative to positive. LG1 2. Derive an accept/reject rule for IRR similar to 13-8 that would make the correct decision on cash flows that are non-normal, but which always have one large positive cash flow at time zero followed by a series of negative cash flows: |Time |0 |1 |2 |3 |4 |5 | |Cash Flow Sign |+ |- |- |- |- |- | With one positive at the beginning and all future cash flows negative, this type of project would be worth more if rates were higher, implying that the NPV profile would be upward-sloping. So the appropriate accept/reject decision rule would look like Accept Project if IRR ≤ Cost of Capital Reject Project if IRR > Cost of Capital LG1 3.

Operations Management Chapter 13

...Operations Management QM 358-740 Summer 2013 Chapter 14 Homework Discussion and Review Questions 6, 8, and 10 1.) (6) Certain Japanese have claimed that Henry Ford’s assembly line provided some of the rationale for lean. What features of assembly lines are common to lean systems? Features of assembly lines that are common to lean systems include: * Muda- waste and inefficiency * Pull system- replacing material or parts based on demand * Kanban- a manual system that signals the need for parts or materials * Heijunka- workload leveling * Kaizen- continuous improvement of the system * Jidoka- quality at the source 2.) (8) Contrast push and pull methods of moving goods and materials through production systems. In a push system work is pushed to the next station as it is completed. Releases are scheduled so output is determined by a set release rate. Since the releases are linked to orders (or forecasts), a push system is controlled by upstream information and is fundamentally make-to-order. In a pull system, a workstation pulls output from the preceding station as it is needed. Releases are authorized. That is, there is an internal signal based on system status that determines whether a release is allowed or not. 3.) (10) What are the benefits and risks of small lot sizes? Lot size directly affects inventory and scheduling. Benefits and risks of small lot sizes include: * Reduced inventory, lower carrying costs...

Peter Drucker Chapter 13

...Why did you select this chapter? What enlightened you? How will you use this in your career? This chapter told me about the emergence of a new order of employees. In the age where there are millions of people constantly competing with each other to get noticed, be heard and land the perfect job opportunity, sometimes one can lose the plot. We often lose perspective of what is actually needed in a bid to be the best. How do we define the best? Have they graduated from the best colleges? Do they have the best internships? Do they about everything? Do they have to know about everything? How does one stay at the top of their game in such cut-throat times? These are questions which have crossed almost every student’s mind and they crossed my mind too. In fact, they consumed me so that my life started revolving around resolving these questions. We start equipping ourselves with skills and knowledge we think will make us viable employees but just having a particular skill is not the end. It is a means to the end, as the author mentioned. He spoke in depth about the knowledge worker and what motivates them to do work. Today, a knowledge worker is a company’s asset. They are the centre when information is processed, assimilated and disseminated in the form of ideas and action plans. They tie their skills, intelligence, and imagination and apply it to real life situations in a way that a computer will not. This just proves that human capital cannot be neglected at the end of...

... the marketing mix? What types of promotional tools are available to companies and what factors influence the choice of tool? How is the promotion plan created? The rest of the chapter answers these questions. Ethics in Marketing Pull Strategy for Prescription Drugs Puts Doctors in the Hot Seat During the diet-drug debacle, doctors wrote millions of prescriptions for the fen-phen drug combination for patients wanting to lose weight, despite little hard scientific evidence. Doctors also prescribed Redux, a drug intended only for the dangerously obese patients, to many patients who wanted to trim ten or twenty pounds. And they wrote some fifteen thousand to twenty thousand prescriptions for the impotency drug Viagra when it first appeared on the market for many men who were not clinically impotent but wanted a boost. Fen-phen and Redux were eventually called off the market, whereas Viagra was found to be potentially dangerous for men with certain types of heart disease. In the fallout, doctors are under attack for prescribing the drugs too much, too readily, and to the wrong patients. Doctors contend it isn’t all their fault. Prodded by an explosion in direct-to-consumer advertising of prescription drugs, patients pressure their physicians for quick treatments. Prozac, the most widely prescribed drug in the world, is often prescribed to patients who are only mildly depressed. Likewise, many patients pressure their family physicians and pediatricians for antibiotics to...

... 13 and a half hours daily from 7:30AM up to 9:00PM seven days a week. Overtime was obligatory, and missing a shift resulted in two or three days pay docked. Including mandatory overtime, workers earned from $211-$268 a month. Most Jordanians won’t work in garment factories, so tens of thousands of guest workers are recruited. They endure illegal abuses, but put up with them to support their families at home. (5) Failure to communicate The plant manager is Palestinian. Supervisors are Bangladeshi. They earn four times worker rates, and are told to drive them as hard as possible as well as spy on and control them. One incident was over worker complaints about lack of water. Supervisor Mr. Rezaul mocked them, saying he’d cut of their penises if they kept complaining. Around the same time, supervisor Mr. Mosharraf slapped a woman very hard in the face for not meeting her quota. Anger was building for months. A work stoppage followed, after which 10-12 policemen entered the factory, threatened the workers and said either work or be handcuffed and imprisoned. The incident continued for days, including more threats and beatings, finally getting about 50 police to charge the dorm, arrest and imprison 24 workers, including 10 men and 14 women. Six were held for over a week, then forcibly deported without their personal belongings. The others were released. While in prison, they were beaten, had no mattresses, no pillows, little food, and unsafe drinking water. The six deported...

Chapter 13

...Chapter 13 Questions 2. If you were an advertising manager for a magazine aimed at senior citizens, what advantages would you cite to potential advertisers? The first thing I would cite to advertisers is that magazines are great for target audiences. Also, magazines last longer than normal print advertisements. Many times you will find magazines that are several months old in doctors offices, waiting rooms, and even in your own home. I would try to sale the flexibility (pg 406) to the potential advertiser. Flexibility gives a farther reach to clients and they are capable of advertising on a broader scale to their target audience. 3. What is the advantage of magazine advertising to businesses that sell to other businesses? The advantage of this is higher quality advertisements. Also by the type of magazine that is being used for advertisements, you are able to better recognize the target audience. Chapter 14 Questions 4. In what ways is cable TV’s selectivity a strength? A drawback? The selectivity of cable TV allows the advertisers to target a specific group of people. A drawback is that the advertisers have to advertise at many different times and on several different channels, making the cost of the advertisement much more expensive. 7. How can radio be best used in an IMC program? Radio reaches a larger audience because many people feel that they are more involved in radio broadcast. Most radio stations and certain...

Explain the cash flow effects of common types of transactions and describe how they are reported in the cash flow statement. Explain how decision makers analyze cash sources and uses listed in the cash flow statement, and describe ratios often used in analyzing cash flows. 494 Chapter 13 The Cash Flow Statement and Decisions UNDERSTANDING THE STATEMENT OF CASH FLOWS Information for Decisions The statement of cash flows reports sources and uses of cash for an entity. This information is used by decision makers when assessing the adequacy of an entity’s cash for future needs and in projecting future cash inflows and outflows. It helps financial statement users answer questions such as these: Is the company generating enough cash from normal operations to continue operating and to make required payments to creditors? Will the company generate sufficient cash for future expansion? Is the company generating sufficient cash to pay future dividends? A statement of cash flows is required by generally accepted accounting principles to be included in a complete set of financial statements. A cash flow statement must be included for each year for which an income or operating statement is included. Thus, the annual reports of most organizations include cash flow statements for either two or three years for comparative purposes. The purpose of the cash flow statement is to report how......

Occasionally the yarn breaks during the spinning process, and an operator ties it back together. Some number of breaks is considered normal; however, too many breaks might mean that the yarn is of poor quality. In order to monitor this process, the quality-control manager randomly selects a spinning machine each hour and checks the number of breaks during a 15-minute period...
