Qs 7 Flashcards
XYZ Ltd organises a meeting in order to decide on the safety stock level of a strategic material which is used in XYZ latest product - DMD. To do this, they must forecast the future demand for this new product. In the meeting, external consultants are invited to join with cross-functional team. Each person of the group anonymously replies to questionnaires and subsequently receives feedback in the form of a statistical representation of the “group response,” after which the process repeats itself. The goal is to reduce the range of responses and arrive at something closer to expert consensus. XYZ Ltd is using which forecasting method?
A. Objective forecasting technique
B. Delphi method
C. Holt-Winters seasonal method
D. Time series analysis
Answer(s): B
Explanation:
Delphi method was developed in the 1950s, originally to forecast the impact of technology on warfare. The method entails a group of experts who anonymously reply to questionnaires and subsequently receive feedback in the form of a statistical representation of the “group response,” after which the process repeats itself. The goal is to reduce the range of responses and arrive at something closer to expert consensus. The Delphi Method has been widely adopted and is still in use today. Delphi method is a subjective forecasting technique Holt-Winters forecasting is a way to model and predict the behavior of a sequence of values over time–a time series. Holt-Winters is one of the most popular forecasting techniques for time series.
It’s decades old, but it’s still ubiquitous in many applications, including monitoring, where it’s used for purposes such as anomaly detection and capacity planning. Time series analysis is a statistical technique that deals with time series data, or trend analysis. Time series data means that data is in a series of particular time periods or intervals. Objective forecasting approaches are quantitative in nature and lend themselves well to an abun- dance of data. There are three categories of objective forecasting methods: time series, caus- al/econometric, and artificial intelligence.

XYZ Ltd has been adopting MRP system for years. The system helps the company improve effi-ciency greatly and generates huge cost-savings. However, MRP system is only limited to produc-tion process management and XYZ management team would like to have better insights into re-sources required across the organisation as a whole.
Which software system would help XYZ management team achieve the above objective?
A. MRP II
B. MPS
C. ERP
D. P2P
Answer(s): C
Explanation:
Enterprise resource planning (ERP) is the integrated management of main business processes, often in real time and mediated by software and technology. ERP provides an integrated and con-tinuously updated view of core business processes using common databases maintained by a data-base management system. ERP systems track business resources–cash, raw materials, production capacity–and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across various departments (manufacturing, purchasing, sales, accounting, etc.) that provide the data. ERP facilitates information flow between all business functions and manages connections to outside stakeholders. Manufacturing resource planning (MRP II) is defined as a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning, and has a simulation capability to answer “what-if” questions and extension of closed-loop MRP. This is not exclusively a software function, but the management of people skills, requiring a dedication to database accuracy, and sufficient computer resources. It is a total company management concept for using human and company resources more productively. A master production schedule (MPS) is a plan for individual commodities to be produced in each time period such as production, staffing, inventory, etc. It is usually linked to manufacturing where the plan indicates when and how much of each product will be demanded. This plan quantifies significant processes, parts, and other resources in order to optimize production, to identify bottlenecks, and to anticipate needs and completed goods. Since a MPS drives much factory activity, its accuracy and viability dramatically affect profitability. Procure-to-pay (P2P) is a term used in the software industry to designate a specific subdivision of the procurement process. The procure-to-pay systems enable the integration of the purchasing department with the accounts payable (AP) department. Some of the largest players of the software industry agree on a common definition of procure-to-pay, linking the procurement process and financial department.

Assuming that all other factors are constant except one, the net present value of a capital expenditure increases when…?
A. The initial cost of a project increases
B. The discounted rate increases
C. Net cash flow during a time period increases
D. Cash outflow during a time period increases
Answer(s): C
Explanation:
Net present value (NPV) is the ‘today’ net value that deprives from ‘future’ cash flow of an invest- ment or a capital purchase.
The following formula is used to calculate NPV
Where:
Rt is the net cash flow (cash inflow - cash outflow) during the period t i is the discount rate
t is the number of time periods
As you can conclude from the above formula, the net present value increases when the numerators (net cash flows) increase and/or denominators (1+i) decrease. So the correct answer should be “Net cash flow during a time period increases”
The purpose of this exercise is to help you identify the factors that influence the net present value and how to increase/decrease NPV in real-world scenario.

Explanation:
To improve the security of a warehouse, alarm systems are commonly used.
Which of the following is an important part of these systems?
A. Sensors
B. Fencing
C. CCTV
D. Lighting
Answer(s): A
Explanation:
The most basic alarm consists of one or more sensors to detect intruders, and an alerting device to indicate the intrusion. However, a typical premises security alarm employs the following compo- nents:
- Premises control unit (PCU), Alarm Control Panel (ACP), or simply panel: The “brain” of the system, it reads sensor inputs, tracks arm/disarm status, and signals intrusions. In modern system, this is typically one or more computer circuit boards inside a metal enclosure, along with a power supply.
- Sensors: Devices which detect intrusions. Sensors may be placed at the perimeter of the protected area, within it, or both. Sensors can detect intruders by a variety of methods, such as monitoring doors and windows for opening, or by monitoring unoccupied interiors for motions, sound, vibration, or other disturbances.
- Alerting devices: These indicate an alarm condition. Most commonly, these are bells, sirens, and/or flashing lights. Alerting devices serve the dual purposes of warning occupants of intrusion, and potentially scaring off burglars. These devices may also be used to warn occupants of a fire or smoke condition.
- Keypads: Small devices, typically wall-mounted, which function as the human-machine interface to the system. In addition to buttons, keypads typically feature indicator lights, a small multi-character display, or both.etc.
- Interconnections between components. This may consist of direct wiring to the control unit, or wireless links with local power supplies.
In addition to the system itself, security alarms are often coupled with a monitoring service. In the event of an alarm, the premises control unit contacts a central monitoring station. Operators at the station see the signal and take appropriate action, such as contacting property owners, notifying police, or dispatching private security forces. Such signals may be transmitted via dedicated alarm circuits, telephone lines, or the internet.

Which of the following best describes the term `periodic review’?
A. Items are reviewed and orders placed depending on requirements
B. Items are reviewed when the Kanban is triggered
C. Items are reviewed when the price is at its lowest
D. Items are reviewed as part of an imprest system
Answer(s): D
Explanation:
Fixed-Time Period System (or Periodic Review system) is the inventory management system in which inventory is checked in fixed time periods, T, and the quantity ordered varies.
The imprest system is a form of financial accounting system. The most common imprest system is the petty cash system. The base characteristic of an imprest system is that a fixed amount is re-served, which after a certain period of time or when circumstances require, because money was spent, it will be replenished.
So the correct answer should be “Items are reviewed as part of an imprest system” LO 2, AC 2.3
What is the different between gross material requirements plan (gross MRP) and a net material requirements plan (net MRP)?
A. The gross requirement doesn’t take taxes into account, whereas the net requirement includes the tax considerations
B. The gross MRP includes consideration of available inventory, whereas the net MRP does not
C. The net MRP includes the amount of inventory on hand, whereas the gross MRP does not
D. The gross MRP is mostly paper-based, but the net MRP must be computerised
Answer(s): B
Explanation:
Material requirement planning (MRP) is a production planning and material (inventory) control system used in manufacturing. Objectives of MRP are to ensure materials are available for production while minimising inventory and to plan production and procurement activities. MRP software combines the master production schedule, the bill of materials and the inventory information to work out the net requirements (net MRP) of what to purchase or produce and when.
These net requirements are worked out using the following equation:
Net requirements = Total requirements - Available inventory
Where:
Total requirement = Gross requirements (gross MRP)
Available inventory = Inventory on hand + Units on order In the other words, Gross MRP = Net MRP + Available inventory,
so the answer should be “The gross MRP includes consideration of available inventory, whereas the net MRP does not” LO 2, AC 2.3
The following are examples of scheduled maintenance except…
A. Oil changes and regular servicing
B. Overhauling of machine
C. Repair signage damage from a recent storm
D. Cleaning of tank
Answer(s): C
Explanation:
Scheduled maintenance is any repair and upkeep work performed within a set timeframe. It details when given maintenance tasks are performed and by whom. Scheduled maintenance may occur at repeating intervals or in response to a work request.
“Overhauling of machine” means that the machine is regularly checked and corrupted parts are replaced if needed.
“Cleaning of tank” and “Oil changes” also occur at time intervals as scheduled So the correct answer is “Repair signage damage from a recent storm”

Which of the following are warehouse layouts that allow the cross aisle to meet picking aisle at angles different from 90 degrees?
- ‘Fan’ shaped layout
- Herringbone-shaped layout
- U-shape layout
- L-shape layout
A. 1 and 2 only
B. 3 and 4 only
C. 1 and 3 only
D. 2 and 3 only
Answer(s): A
Explanation:
In a traditional warehouse, storage racks are arranged to create parallel picking aisles, perhaps with one or more cross aisles to allow workers to move quickly between picking aisles. This structure forces workers to travel rectilinear distances (north-south and east-west) to picking locations.
Kevin R. Gue and Russell D. Meller proposed alternative aisle designs:
- The ‘Fan’ shaped layout (or “Flying V”). This layout maintains parallel picking aisles, but al-lows the cross aisle to take on a different shape. If travel begins and ends at the bottom of the V, Gue and Meller expected distance to retrieve a single pallet is 10% less in this warehouse than in an equivalent traditional design.
- The Herringbone-shaped layout (or commonly referred as Fishbone layout) combines the verti-cal picking rows of a traditional warehouse with a second set of horizontal picking rows, divided by a V- shaped diagonal alley crossing the entire warehouse. This simple modification to the typical warehouse design allows employees (e.g. a forklift driver) to increase travel speed between picking locations. Efficiency gains achieved through a layout reconfiguration would reduce picking cost up to 23% compared to an equivalent warehouse using a traditional configuration.

A major investment bank is planning to purchase a complex banking system that will interface with multiple applications at varying times of the day. Before deploying the system, there are various levels of testing that must be performed through joint testing between the in-house team and off- shore testing consultants. The testing will be performed in a resource-constrained shared environment and managed by the on-shore development team. The costs for testing are generally classified as…?
A. Insurance
B. Maintenance costs
C. Acquisition costs
D. Purchase prices
Answer(s): C
Explanation:
In the scenario, the buying organisation (investment bank) must conduct various types of testing before the deployment of the software system. These tests can be functional testing, factory ac- ceptance testing and/or user acceptance testing. The costs for all these types of testing are classified as acquisition costs with regards of total cost of ownership.

ANTA Logistics is looking for a place to build a new, integrated cold chain facility, “Chill Hub”, to its customers.
Which of the following need to be considered when selecting the location of the new facility? Select TWO that apply.
A. Availability of the building
B. Ease of objective forecasting on inventory level
C. Volume of obsolescent stock
D. Accessibility to roads and highways
E. Availability of product coding system
Answer(s): A,D
Explanation:
There are many different factors that must be considered when assessing warehouse and stock locations:
- Operating cost of the location or area
- Availability and suitability of warehouses
- Availability of manpower or labour
- Proximity to suppliers and customers
- Access to transport infrastructure (domestic and international) - The political and security environment of the location LO 1, AC 1.1
The ABC approach involves classifying inventory items by unit cost, with expensive items classi-fied as A' items and low cost items classified as
C’ items. Is this statement true?
A. Yes, ‘A’ items represent approximately 20% of total unit prices
B. Yes, ‘C’ items with the lowest unit prices are the tail spends
C. No, ABC analysis considers the usage of each inventory item
D. No, ABC analysis considers the supply risks associated with an inventory item
Answer(s): C
Explanation:
ABC analysis is an approach for classifying inventory items based on the items’ consumption val-ues. Consumption value is the total value of an item consumed over a specified time period, for example a year. The approach is based on the Pareto principle to help manage what matters and is applied in this context:
- A items are goods where annual consumption value is the highest. Applying the Pareto principle (also referred to as the 80/20 rule where 80 percent of the output is determined by 20 percent of the input), they comprise a relatively small number of items but have a relatively high consumption value. So it’s logical that analysis and control of this class is relatively intense, since there is the greatest potential to reduce costs or losses.
- B items are interclass items. Their consumption values are lower than A items but higher than C items. A key point of having this interclass group is to watch items close to A item and C item classes that would alter their stock management policies if they drift closer to class A or class C. Stock management is itself a cost. So there needs to be a balance between controls to protect the asset class and the value at risk of loss, or the cost of analysis and the potential value returned by reducing class costs. So, the scope of this class and the inventory management policies are determined by the estimated cost-benefit of class cost reduction, and loss control systems and processes.
- C items have the lowest consumption value. This class has a relatively high proportion of the total number of lines but with relatively low consumption values. Logically, it’s not usually cost-effective to deploy tight inventory controls, as the value at risk of significant loss is relatively low and the cost of analysis would typically yield relatively low returns.

Which of the following costs does the EOQ minimise?
A. Total cost of safety stock
B. Total cost of ordering inventory
C. Total cost of annual inventory cost
D. Total cost of carrying stock
Answer(s): C
Explanation:
Economic order quantity (EOQ) was developed in 1913 by Ford W. Harris and has been refined over time. The formula assumes that demand, ordering, and holding costs all remain constant. The EOQ minimizes the total annual inventory cost.
EOQ formula is as follow:

What is the stock turn for a store holding products to the value of £250,000 with annual sales of these products amounting to £1,000,000?
A. 10
B. 4
C. 0.25
D. 0.4
Answer(s): B
Explanation:
Calculating Inventory Turnover (Stock Turn)
As with a typical turnover ratio, inventory turnover details how much inventory is sold over a period. To calculate the inventory turnover ratio, cost of goods (COGS) is divided by the average inventory for the same period.1
Cost of Goods Sold ÷ Average Inventory or Sales ÷ Inventory
In this exercise, the stock turn equal to sales divided by inventory, or 1,000,000:250,000 = 4.

Which of the following is essential to effective implementation of just-in-time?
A. Regular machine changeovers
B. Larger warehouse for larger amount of inventory
C. No need for smoothing production
D. Strong links between the suppliers and the buying organisation
Answer(s): D
Explanation:
For JIT manufacturing to succeed, companies must have steady production, high-quality workmanship, glitch-free plant machinery, and reliable suppliers. JIT production systems cut inventory costs because manufacturers do not have to pay storage costs. Manufacturers are also not left with unwanted inventory if an order is canceled or not fulfilled.

The amount of inventory available at the start of an accounting period is known as…?
A. Buffer stock
B. Work-in-progress
C. Opening stock
D. Closing stock
Answer(s): C
Explanation:
Opening stock is the starting amount of inventory that a business has at a fixed moment in time. This could be the start of a financial year, another reporting period or ad hoc stocktake. The concept of opening stock mush not be confused with raw materials
Closing stock is the inventory held at the end of the period under consideration. Thus, the closing stock of one period is automatically the opening stock for the next. Work in progress is the stock part-way through a manufacturing process; in the service sectors the term is also used for anything between order and delivery. Buffer stock (safety stock) is the stock held as a contingency or insurance against disruption or unexpected demand.

Which of the following are most likely to be the purposes of packing and packaging?
1. To bring the product cost down
2. To protect the product
3. To improve the product recognition
4. To test the product durability
A. 1 and 2 only
B. 3 and 4 only
C. 2 and 3 only
D. 1 and 4 only
Answer(s): C
Explanation:
It would be really convenient if we could just hand our products directly to the customers, but that’s not possible. Packaging needs to be done for several reasons. Here are some of the most prominent ones:
1. Safety: Packaging is used to keep your product safe from external factors. It also prevents human tampering. If you want to sell fruit juice, you just can’t hand it over to customers. It should be packaged in something, like a stand up pouch.
2. Brand visibility: You provide the best product in your category and you want your customers to remember that. How else will you do that without using the right kind of creative food packaging?
3. Bundling it together: If you want to sell an ounce of something, you need to create a packet so that the right amount is bundled together.
4. Theft prevention: If you sell your product loose, there are chances that the retailer doesn’t give the right amount to the customer and saves some part for himself. There are other cases too where theft can be done in the absence of packaging.
Apart from these four, there are many other reasons why you should package your products.

Which of the following are features of product codes?
1. Product codes link to products’ characteristics
2. A product code must comply with international standards
3. Many internal processes use the product codes as facilitators
4. There are no duplicate product codes
A. 2 and 4 only
B. 3 and 4 only
C. 1 and 3 only
D. 1 and 2 only
Answer(s): C
Explanation:
The product code is often the key to obtaining documentation relating to products.
Product codes are often use to link to internal processes. Some computerised inventory systems trigger alerts when specific items or volume are ordered - this could be an out-of-stock warning or potential volume errors.
In many cases, an organisation will use its own product code system. The organisation constructs a code that is effective and fits with its software and the variety of items covered. So these codes may or may not comply with any international standards (such as GS1 specifications, ISO standards, etc.). As organisations make up the code themselves, the codes may look identical to others. For example, SKU414675 reveals that it is used for many items, including the following:
- A UK wholesaler’s six-pack of branded cola
- An Australian snack food
- UK flower seeds
- An Italian desk sold in Japan
- A Brazilian light fitting

Which of the following statements is true?
A. All indirect supplies are independent demand items
B. Number of independent demand items may be derived from the forecast
C. Dependent demand items are not directly correlated with production rate
D. Car engine is an example of independent demand items in a car assembly plant
Answer(s): B
Explanation:
Dependent demand is the requirement for stock item which is directly related to and therefore de- pendent upon the rate of production (examples are: raw materials, components, energy). Independent demand is the requirement for stock item which is not directly related to, and is therefore independent of rate of production.
‘Number of independent demand items may be derived from the forecast’: Although independent demand is called thus, it can still be influenced by economic factors external to the demand-supply model such as general consumer sentiment and consumers’ available disposal income. However, businesses that need to predict the number of products with independent demand needed to sate their customers have it easier than businesses that must calculate the demand for products with dependent demand because there are fewer factors to consider. ‘Dependent demand items are not directly correlated with production rate’: As mentioned above, dependent demand items are directly correlated with production rate. ‘All indirect supplies are independent demand items’: Though most indirect supplier are inde- pendent demand, some are determined by the production rate, i.e. energy consumption of a major machinery.
‘Car engine is an example of independent demand items in a car assembly plant’: Car engine is a component in car which is the finished good of a car assembly plant, it is a dependent demand item.

Which of the following should be considered when an organisation plans for disposing obsolescent and redundant stock? Select TWO that apply.
A. Financial costs
B. Economic order quantity
C. ABC analysis
D. Takt time
E. Environmental issues
Answer(s): A,E
Explanation:
If the planning and mitigation measures fail and redundant or obsolete stock is identified, it needs to be removed from the current inventory location as quickly as possible. There are some methods to deal with these types of stock. The worst case scenario is disposal to landfill, which is inadvisable if it can be avoided, both from environment point of view and the financial costs of such disposal. For example, the problem of obsolete pesticides remains extremely serious and urgent. Many of the stocks identified continue to deteriorate thereby giving rise to an ever escalating source of severe pollution and posing a threat to human health, the environment and development in particular. To reduce the impact of obsolete pesticides on environment, FAO initiated a project in Yemen in which a total of 262 tonnes of obsolete pesticides were removed from 20 different sites and successfully disposed of between March and June 1996. The major field operation was completed in six weeks during which period almost all obsolete pesticides were brought to a central location and subsequently shipped to the United Kingdom for incineration.

Which of the following are the different types of inventory that a manufacturing company usually has?
1. Work in progress
2. Economic order quantity
3. Raw materials
4. Finished goods
A. 1, 3 and 4
B. 1, 2 and 4
C. 2, 3 and 4
D. 2, 3 and 4
Answer(s): A
Explanation:
The normal breakdown in a manufacturing organisation would be raw materials, components, work in progress and finished goods.
Following are the different types of inventory:
Raw materials are the basic materials that a manufacturing company buys from its suppliers, and that is used by the former to convert them into the final products by applying a set of manufacturing processes. For example, aluminum scrap is the raw material for a company that produces aluminum ingots. Flour is the raw material for a company that produces bread or pizza. Similarly, metal parts and ingots are the raw materials bought by a company that manufactures cars, and crude oil is the raw material for an oil refinery.
Work in progress inventory can also be called semi-finished goods. They are the raw materials that have been taken out of the raw materials store and are now undergoing the process of their conversion into the final products. These are the partly processed raw materials lying on the production floor. And they have also not reached the stage where they have been converted into the final product.
Finished goods are indeed the final products obtained after the application of the manufacturing processes on the raw materials and the semi-finished goods discussed above in the article. They are saleable, and their sale contributes fully to the revenue from the core operations of the company.
Do all types of warehouses require access to daylight to reduce the cost of electricity?
A. No, because only ventilation can help to reduce the humidity in the warehouse
B. No, because some types of stock are sensitive to sunlight
C. Yes, because sunlight sterilises inventories in damp conditions
D. Yes, because organisation’s need for artificial lighting and heating will reduce
Answer(s): B
Explanation:
The design of a building should consider the advantages of natural light as this can reduce the cost of artificial lighting and improve the environmental performance of the building. Daylight entering the building can also help reduce heating costs. Unfortunately some stocks react badly to direct sunlight, and some stock reacts badly to extreme of temperature or may require a specific temperature for storage. Some stock may require a warmer temperature than the ambient temperature and other stocks may require cooler temperature. For example, fabric and garment are sensitive to direct sunlight as ultraviolet light catalyses a reaction between the water present in all fabrics and atmospheric oxygen to create hydrogen peroxide. This is a bleaching agent and breaks down the chemical bonds that give dyes their colour.
