Supply Chain Management ExerciseTrue or False1. A supply chain includes only the organizations directly involved in supplying components needed for manufacturing.Answer: FalseDifficulty: Moderate2. A supply chain consists of all parties involved, directly or indirectly, in fulfilling a customer request.Answer: TrueDifficulty: Moderate3. A supply chain could be more accurately described as a supply network or supply web.Answer: TrueDifficulty: Moderate4. The objective of every supply chain is to maximize the overall value generated.Answer: TrueDifficulty: Easy5. The objective of every supply chain is to maximize the value generated for the manufacturing component of the supply chain.Answer: FalseDifficulty: Moderate6. All supply chain activities within a firm belong to one of three macro processes CRM, ISCM and SRM.Answer: TrueDifficulty: Easy7. There is a close connection between the design and management of supply chain flows and the success of a supply chain.Answer: TrueDifficulty: Easy8. A companys competitive strategy defines the set of customer needs that it seeks to satisfy through its products and services.Answer: TrueDifficulty: Easy9. The value chain emphasizes the close relationship between all the functional strategies within a company.Answer: TrueDifficulty: Moderate10. A companys product development strategy defines the set of customer needs that it seeks to satisfy through its products and services.Answer: FalseDifficulty: Moderate11. A companys product development strategy specifies the portfolio of new products that it will try to develop.Answer: TrueDifficulty: Easy12. A companys supply chain strategy specifies how the market will be segmented and how the product will be positioned, priced, and promoted.Answer: FalseDifficulty: Easy13. A companys supply chain strategy determines the nature of procurement and transportation of materials as well as the manufacture and distribution of the product.Answer: TrueDifficulty: Easy14. The degree of supply chain responsiveness should be consistent with the implied uncertainty.Answer: TrueDifficulty: Easy15. The degree of supply chain responsiveness does not need to be consistent with the implied uncertainty.Answer: FalseDifficulty: Moderate16. The two major types of facilities are distribution sites and storage sites.Answer: FalseDifficulty: Moderate17. Inventory is an important supply chain driver because changing inventory policies can dramatically alter the supply chains efficiency and responsiveness.Answer: TrueDifficulty: Moderate18. Information is potentially the biggest driver of performance in the supply chain as it directly affects each of the other drivers.Answer: TrueDifficulty: Easy19. The high utilization facility will have no more difficulty responding to demand fluctuations than one with a lot of unused capacity.Answer: False Difficulty: Easy20. Stock keeping unit (SKU) storage is the warehousing methodology that uses a traditional warehouse to store all of one type of product together.Answer: TrueDifficulty: Moderate21. Warehouse unit storage is the warehousing methodology that uses a traditional warehouse to store all of one type of product together.Answer: FalseDifficulty: Moderate22. Distribution occurs between every pair of stages in the supply chain.Answer: TrueDifficulty: Moderate23. Distribution only occurs between manufacturing and consumers in the supply chain.Answer: FalseDifficulty: Moderate24. Companies in the same industry often select very different distribution networks, because the choice of the distribution network can be used to achieve a variety of supply chain objectives ranging from low cost to high responsiveness.Answer: TrueDifficulty: Moderate25. The main advantage of a distribution network with local storage is that it can lower the delivery cost and provide a faster response than other networks.Answer: TrueDifficulty: Moderate26. When designing supply chain networks, companies must build appropriate flexibility to help counter fluctuations in exchange rates and demand across different countries.Answer: TrueDifficulty: Moderate27. Inventory and facility costs increase as the number of facilities in a supply chain increase. Answer: TrueDifficulty: Moderate28. Transportation costs increase as the number of facilities is increased.Answer: FalseDifficulty: Moderate29. When faced with a network design decision, the goal of a manager is to design a network that minimizes the firms costs while satisfying customer needs in terms of demand and responsiveness.Answer: FalseDifficulty: Hard30. The supply chain network is designed to maximize total profits, taking into account the expected margin and demand in each market, various logistics and facility costs, and the taxes and tariffs at each location.Answer: TrueDifficulty: Easy31. Decisions made during the supply chain design phase regarding significant investments in the supply chain, such as the number and size of plants to build, the number of trucks to purchase or lease, and whether to build or lease warehouse space, cannot be altered in the short term.Answer: TrueDifficulty: Moderate32. Decisions made during the supply chain design phase regarding significant investments in the supply chain, such as the number and size of plants to build, the number of trucks to purchase or lease, and whether to build or lease warehouse space, rarely remain in place for several years.Answer: FalseDifficulty: Moderate33. Decisions made during the supply chain design phase regarding significant investments in the supply chain, such as the number and size of plants to build, the number of trucks to purchase or lease, and whether to build or lease warehouse space, define the boundaries within which the supply chain must compete.Answer: TrueDifficulty: Moderate34. Long-term contracts for both warehousing and transportation requirements will be more effective if the demand and price of warehousing do not change in the future or if the price of warehousing goes up.Answer: TrueDifficulty: Easy35. Long-term contracts for both warehousing and transportation requirements will be more effective if either demand or the price of warehousing drops in the future.Answer: FalseDifficulty: Moderate36.

The rate of return k is also referred to as the present value of capital.Answer: FalseDifficulty: Easy38. A negative NPV for an option indicates that the option will lose money for the supply chain.Answer: TrueDifficulty: Moderate39. The decision with the lowest NPV will provide a supply chain with the highest financial return.Answer: FalseDifficulty: Moderate40. In reality, demand and prices are highly uncertain and are likely to fluctuate during the life of any supply chain decision.Answer: TrueDifficulty: Moderate41. The goal of aggregate planning is to satisfy demand in a way that minimizes profit.Answer: FalseDifficulty: Easy42. Aggregate planning is a process by which a company determines levels of capacity, production, subcontracting, inventory, stockouts, and even pricing over a specified time horizon.Answer: TrueDifficulty: Moderate43. Aggregate planning solves problems involving aggregate decisions rather than stock keeping unit (SKU) level decisions.Answer: TrueDifficulty: Easy44. Forecasting errors are dealt with in aggregate plans using either safety backlog or safety capacity.Answer: FalseDifficulty: Moderate45. Safety inventory is defined as inventory held to satisfy demand that is higher than forecasted.Answer: TrueDifficulty: Easy46. Safety capacity is defined as capacity used to satisfy demand that is lower than forecasted.Answer: FalseDifficulty: Easy47. Companies should work with downstream partners to produce forecasts and with upstream partners to determine constraints when doing aggregate planning.Answer: TrueDifficulty: Easy48. The aggregate plan should be viewed primarily as an in-house tool that does not need to be communicated to supply chain partners.Answer: FalseDifficulty: Easy49. Given that forecasts are always wrong to some degree, the aggregate plan needs to have some flexibility built into it if it is to be useful.Answer: TrueDifficulty: Moderate50. With supply and demand management decisions being made independently, it is easier to coordinate the supply chain, thereby increasing profit.Answer: FalseDifficulty: Moderate51. A firm can vary supply of product by controlling production capacity and inventory.Answer: TrueDifficulty: Easy52. A firm that uses flexible work hours from the workforce to manage capacity to better meet demand is using a seasonal workforce.Answer: FalseDifficulty: Moderate53. Offering a promotion during a peak period that has significant forward buying creates even more variable demand than before the promotion.Answer: TrueDifficulty: Easy54. Average inventory decreases if a promotion is run during the peak period and increases if the promotion is run during the off-peak period.Answer: FalseDifficulty: Easy55. Promoting during a peak demand month may decrease overall profitability if a significant fraction of the demand increase results from a forward buy.Answer: TrueDifficulty: Hard56. As forward buying becomes a smaller fraction of the demand increase from a promotion, it is less profitable to promote during the peak period.Answer: FalseDifficulty: Hard57. As the product margin declines, promoting during the peak demand period becomes less profitable.Answer: TrueDifficulty: Easy58. Cycle inventory exists because producing or purchasing in large lots allows a stage of the supply chain to exploit economies of scale and increase cost.Answer: FalseDifficulty: Moderate59. A lot or batch size is the quantity that a stage of the supply chain either produces or purchases at a given time.Answer: TrueDifficulty: Moderate60. Cycle inventory is the physical inventory in the supply chain due to either production or purchases demanded by the customer.Answer: TrueDifficulty: Moderate61. The inventory profile is a plot depicting the level of inventory over time.Answer: TrueDifficulty: Easy62. A discount is volume-based if the pricing schedule offers discounts based on the quantity ordered in a single lot.Answer: FalseDifficulty: Hard63. A discount is volume-based if the discount is based on the total quantity purchased over a given period, regardless of the number of lots purchased over that period.Answer: TrueDifficulty: Easy64. Pricing schedules with all unit quantity discounts encourage retailers to increase the size of their lots, which reduces the average inventory and flow time in a supply chain.Answer: FalseDifficulty: Moderate65. Safety inventory is inventory carried for the purpose of satisfying demand that exceeds the amount forecasted for a given period.Answer: TrueDifficulty: Moderate66. Safety inventory is carried because demand forecasts are accurate and a product shortage may result if the forecast demand exceeds the actual demand.Answer: FalseDifficulty: Moderate67. Raising the level of safety inventory increases product availability and thus the margin captured from customer purchases.Answer: TrueDifficulty: Moderate68. Raising the level of safety inventory increases inventory holding costs.Answer: TrueDifficulty: Easy69. Carrying excessive inventory can help counter demand volatility when new products come on the market.Answer: FalseDifficulty: Moderate70. The appropriate level of safety inventory is determined by the uncertainty of both demand and supply and the desired level of cycle inventory.Answer: FalseDifficulty: Moderate71. As the uncertainty of supply or demand grows, the required level of safety inventories increases.Answer: TrueDifficulty: Moderate72. As the desired level of product availability increases, the required level of safety inventory decreases.Answer: FalseDifficulty: Easy 73. Lead time is the gap between when an order is placed and when it is received.Answer: TrueDifficulty: Easy74. Periodic review policies require more safety inventory than continuous review policies for the same level of product availability.Answer: TrueDifficulty: Easy75. When using a continuous review policy, a manager has to account for the uncertainty of demand during the lead time and the review interval.Answer: FalseDifficulty: EasyMultiply Choice1.
