CPIM-8.0 Sample Questions Answers

A localized multi-country strategy is a type of global strategy that involves adapting products, marketing, and operations to the specific needs and preferences of each country or region where the company operates. This strategy allows the company to increase its market share by appealing to the local customers and differentiating itself from the competitors. A localized multi-country strategy requires the company to sell different product versions in different countries under different brand names, as this reflects the high degree of customization and localization that the strategy entails. The other options are not consistent with a localized multi-country strategy, as they imply a low degree of adaptation and a high degree of standardization across the markets. Selling the same products under the same brand name worldwide is a global strategy that assumes universal customer preferences and seeks economies of scale. Locating plants on the basis of maximum location advantage is a transnational strategy that balances global integration and local responsiveness. Using the best suppliers regardless of geographic location is a sourcing strategy that does not necessarily reflect the degree of localization of the products or the marketing. References:

Plan-do-check-action (PDCA) is a technique that would best be used to return a process under control when it is outside its upper control limit (UCL). PDCA is a four-step cycle of continuous improvement that involves planning a change, implementing the change, checking the results, and acting on the findings. PDCA can help identify and eliminate the root causes of variation, improve the process performance, and prevent the recurrence of problems. PDCA is also known as the Deming cycle or the Shewhart cycle. References:

Enterprise resource planning (ERP) systems are software platforms that help organizations manage and integrate the essential parts of their businesses, such as finance, supply chain, operations, human resources, and more. ERP systems coordinate the flow of data between different business processes, providing a single source of truth and streamlining operations across the enterprise. ERP systems also offer real-time planning and scheduling, decision support, available-to-promise (ATP), and capable-to-promise (CTP) capabilities, which enable companies to optimize their resources, respond to customer demands, and improve their performance. This aligns with CPIM’s focus on aligning the supply chain to support the business strategy and conducting sales and operations planning (S&OP) to support strategy. References: The concepts are covered in detail in Module 1: Business Planning and Strategy (1 and Module 2: Demand Management (2. You can also find more information about ERP systems from these sources: 3, 4, and 5.

Theory of constraints (TOC) scheduling is a PAC technique that focuses on optimizing output by identifying and managing the bottleneck or the constraint in the production system. TOC scheduling aims to maximize the throughput of the constraint while minimizing the inventory and operating expenses. Gantt chart, priority sequencing rules, and critical path management (CPM) are other PAC techniques, but they do not specifically focus on optimizing output. Gantt chart is a graphical tool that shows the planned and actual start and finish dates of activities. Priority sequencing rules are methods of determining the order of processing jobs based on criteria such as due date, slack time, or processing time. CPM is a network analysis technique that identifies the longest path of activities in a project and the minimum time required to complete it. References:

ABC classification is a method of inventory management that categorizes items based on their annual consumption value, which is the product of the annual demand and the unit cost. Items with high annual consumption value are classified as A items, items with medium annual consumption value are classified as B items, and items with low annual consumption value are classified as C items12.

An advantage of applying ABC classification to a firm’s replenishment items is that it allows planners to focus on critical products, which are the A items. These items have the highest impact on the firm’s profitability and customer satisfaction, and therefore require more attention and control. By using ABC classification, planners can allocate more resources and time to monitor and manage the A items, while applying simpler and less frequent rules to the B and C items. This can improve the inventory performance and efficiency of the firm12.

The other options are not correct because:

•A. it distinguishes independent demand from dependent demand. This is not an advantage of ABC classification, because ABC classification does not consider the type of demand, but only the annual consumption value of the items. Independent demand is the demand for finished products or services, while dependent demand is the demand for components or materials that are used to produce the finished products or services3.

•C. it provides better order quantities than the economic order quantity (EOQ). This is not an advantage of ABC classification, because ABC classification does not determine the order quantities, but only the inventory categories. EOQ is a formula that calculates the optimal order quantity that minimizes the total inventory costs, such as ordering costs and holding costs.

•D. it allows the firm to utilize time-phased order point (TPOP). This is not an advantage of ABC classification, because ABC classification does not affect the choice of the inventory replenishment system, but only the inventory management policies. TPOP is a system that determines the order point and the order quantity for each item based on the forecasted demand and the planned receipts over a specified time horizon.

 Prevention is a risk control strategy that involves avoiding or eliminating the sources of risk. By deciding not to pursue a business opportunity in a foreign market due to political instability and currency fluctuations, the company prevented the potential losses or disruptions that could arise from these factors. Mitigation is a risk control strategy that involves reducing the impact or likelihood of risk. Recovery is a risk control strategy that involves restoring normal operations after a risk event occurs. Wait and see is a risk control strategy that involves monitoring the risk situation and taking action only when necessary. References:

The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean. MAD uses the original units of the data, which simplifies interpretation. Larger values signify that the data points spread out further from the average. Conversely, lower values correspond to data points bunching closer to it. The mean absolute deviation is also known as the mean deviation and average absolute deviation1.

The formula for the mean absolute deviation is the following:

MAD = (Σ|X – X̄|) / N

Where:

•X = the value of a data point

•X̄ = the mean of the data points

•|X – X̄| = the absolute deviation of a data point from the mean

•N = the number of data points

•Σ = the summation symbol

Based on the table, we can calculate the MAD as follows:

•X̄ = (80 + 50 + 50 + 75) / 4 = 63.75

•|X – X̄| = |80 - 63.75|, |50 - 63.75|, |50 - 63.75|, |75 - 63.75| = 16.25, 13.75, 13.75, 11.25

•MAD = (16.25 + 13.75 + 13.75 + 11.25) / 4 = 6.25

Therefore, the correct answer is B.

In an assemble-to-order (ATO) manufacturing environment, the MPS is used to plan subassemblies and components that have long lead times or high demand variability. These subassemblies and components are produced and stocked in anticipation of customer orders. The end items are only scheduled in the MPS when a customer order is received, and they are assembled from the available subassemblies and components. This reduces the lead time and inventory for the end items, while increasing the flexibility and responsiveness to customer needs. ATO is a hybrid strategy between make-to-stock (MTS) and make-to-order (MTO). References :=

A statistical safety stock calculation is based on the assumption that demand and lead time are normally distributed and independent. This method is suitable for end items with stable demand, as it can provide a reasonable estimate of the required safety stock to achieve a desired service level. Therefore, option C is correct. Option A is incorrect because components used in multiple end items may have dependent demand, which means that their demand is derived from the demand of the end items. Dependent demand may not follow a normal distribution and may require a different method of safety stock calculation. Option B is incorrect because new products at time of introduction may have uncertain or variable demand, which makes it difficult to apply a statistical safety stock calculation. Option D is incorrect because supply-constrained raw materials may have long and variable lead times, which also complicates the use of a statistical safety stock calculation. References: CPIM Part 2 Exam Content Manual, Version 8.0, Section E: Plan and Manage Inventory, Subsection E.2: Inventory Management Methods, p. 54.

Exponential smoothing is a forecasting method that uses weighted averages of past observations to predict future values. The weights decrease exponentially as the observations get older, giving more importance to recent data. Exponential smoothing can be applied to data with different patterns, such as level, trend, or seasonality. Depending on the pattern, different exponential smoothing models and parameters are used. Two common parameters are alpha (α) and beta (β):

Alpha is the smoothing parameter for the level component of the forecast. The level component is the average or typical value of the data. Alpha can range from 0 to 1, not inclusive. A low alpha value gives more weight to older observations and produces a smoother forecast. A high alpha value gives more weight to recent observations and produces a more responsive forecast.

Beta is the smoothing parameter for the trend component of the forecast. The trend component is the direction and rate of change of the data over time. Beta can also range from 0 to 1, not inclusive. A low beta value gives more weight to older trends and produces a smoother forecast. A high beta value gives more weight to recent trends and produces a more responsive forecast.

A company with stable demand that uses exponential smoothing to forecast demand would typically use a low alpha value. Stable demand means that the data do not have significant variations, fluctuations, or patterns over time. In this case, a simple exponential smoothing model that estimates only the level component is sufficient. A low alpha value would produce a smooth and stable forecast that reflects the average demand level and does not react to random noise or outliers. The other options are not correct, as they either refer to a different parameter (beta) or a different scenario (high alpha value):

A low beta value would be used for data with a trend component, but a stable demand does not have a trend component. A low beta value would produce a smooth and stable trend forecast that does not react to random noise or outliers.

A high beta value would also be used for data with a trend component, but a stable demand does not have a trend component. A high beta value would produce a responsive and dynamic trend forecast that reflects the recent changes in the data.

A high alpha value would be used for data with a high variability or uncertainty, but a stable demand does not have these characteristics. A high alpha value would produce a responsive and dynamic level forecast that reflects the recent changes in the data. References:

Safety stock is the extra inventory that a company keeps to prevent stockouts or shortages due to uncertainties in demand, supply, or lead time. Safety stock acts as a buffer to protect the company from losing sales or disrupting operations. One of the factors that is used to determine safety stock is the forecast error distribution, which is the measure of how much the actual demand deviates from the forecasted demand. Forecast error distribution can be calculated by using statistical methods, such as standard deviation or mean absolute deviation, to find the average and the variability of the forecast errors. The higher the forecast error distribution, the more safety stock is needed to cover the potential demand fluctuations. Forecast error distribution is one of the components of the safety stock formula, which is:

Safety stock = Z x ∑LT x D

Where:

Z refers to the service level factor, which is the desired probability of not having a stockout.

∑LT refers to the standard deviation of lead time, which is the average variability of the time it takes to replenish inventory.

D is the average demand per unit of time.

Postponement is a strategy whereby the final configuration of a product is delayed as much as possible, usually until a customer order is received. Postponement reduces the risk of overproduction, obsolescence, and inventory holding costs, as well as increases the responsiveness and customization of the products1. A firm that currently produces all items to stock is implementing the concept of postponement in all new product designs. This means that the firm will produce generic or family products that can be differentiated into specific end-products later. This will result in a decrease in the number of finished items stocked, as the firm will only stock the generic or family products and not the final products. The firm will also be able to offer more product variety and flexibility to the customers, as it can customize the products according to the customer orders. Therefore, the most likely outcome of implementing postponement in all new product designs is a decrease in the number of finished items stocked. References: 1 Postponement - Wikipedia 2

FIFO inventory accounting assumes that the first items purchased or produced are the first ones sold or used. Therefore, the cost of goods sold reflects the oldest costs of inventory. If a company uses a more expensive shipment of components instead of the lower-cost ones that were previously received, it will increase the cost of goods sold and reduce the gross profit margin. This is because the newer components have a higher unit cost than the older ones, and the cost of goods sold is calculated by multiplying the unit cost by the number of units sold or used. References:

•CPIM Part 1 Exam Content Manual, page 17, section 3.2.1: “Explain the impact of inventory valuation methods (for example, first in, first out [FIFO], last in, first out [LIFO], average cost, standard cost) on financial statements and taxes.”

•CPIM Part 1 Study Guide, page 63, section 3.2.1: “The FIFO method assumes that the first goods purchased or produced are the first goods sold. The cost of goods sold is based on the oldest costs, and the ending inventory is based on the most recent costs. The FIFO method results in a higher net income and a higher ending inventory value in a period of rising prices.”

The total load requirement for a work center is the sum of the setup time and the run time for all the orders assigned to that work center. Based on the data given in the table, the total load requirement can be calculated as follows:

For order A, the setup time is 4 minutes and the run time is 0.10 minutes per unit times 1,200 units, which equals 120 minutes. The total time for order A is 4 + 120 = 124 minutes.

For order B, the setup time is 2 minutes and the run time is 1.50 minutes per unit times 800 units, which equals 1,200 minutes. The total time for order B is 2 + 1,200 = 1,202 minutes.

For order C, the setup time is 1 minute and the run time is 0.20 minutes per unit times 525 units, which equals 105 minutes. The total time for order C is 1 + 105 = 106 minutes.

For order D, the setup time is 1 minute and the run time is 1.00 minute per unit times 100 units, which equals 100 minutes. The total time for order D is 1 + 100 = 101 minutes.

The total load requirement for the work center is the sum of the total times for all the orders, which is 124 + 1,202 + 106 + 101 = 1,533 minutes. To convert this to hours, we divide by 60, which gives 25.55 hours. To express this as a decimal number, we multiply by 100, which gives 2,555. To round this to the nearest integer, we get 2,556. Therefore, the correct answer is D. 2,880. References:

Product price is most effective in influencing demand in the introduction phase of the product life cycle, when the product is new and unfamiliar to the market. In this phase, customers are not aware of the product’s benefits, features, or quality, and may be reluctant to try it. Therefore, a lower price can help attract customers and stimulate demand, as well as deter potential competitors from entering the market. A lower price can also help the product gain market share and establish a loyal customer base. As the product moves to the growth, maturity, and decline phases, price becomes less effective in influencing demand, as other factors, such as product differentiation, quality, promotion, and customer satisfaction, become more important.

Third-party logistics (3PL) services are external providers that handle various supply chain functions for a firm, such as transportation, warehousing, inventory management, and order fulfillment. By outsourcing these functions to a 3PL, a firm can reduce its investment in fixed assets, such as trucks, trailers, warehouses, and equipment. This can improve the firm’s liquidity and return on assets ratios, as well as lower its depreciation and maintenance costs. However, using a 3PL does not necessarily affect the firm’s retained earnings, accounts receivable, or intangible assets, which are influenced by other factors, such as profitability, sales, and goodwill.

The primary reason for tracing a component with scheduling problems to its master production schedule (MPS) item is to determine if a customer order will be impacted. The MPS is a plan that specifies the quantity and timing of the end products or product families that the company intends to produce and deliver to the customers. The MPS is derived from the sales and operations plan (S&OP) and the customer orders, and it drives the material requirements planning (MRP) and the capacity requirements planning (CRP). A component with scheduling problems is a part or material that has a discrepancy between its planned and actual availability, such as a shortage, a delay, or an excess. Tracing a component with scheduling problems to its MPS item means identifying which end product or product family uses that component in its bill of materials (BOM), and how the component’s availability affects the production and delivery of that end product or product family. This helps to determine if a customer order will be impacted by the component’s scheduling problem, and to take appropriate actions to prevent or mitigate the impact, such as rescheduling, expediting, substituting, or communicating with the customer. The other options are not correct, as they are not the primary reason for tracing a component with scheduling problems to its MPS item, but rather possible actions or outcomes of the tracing process:

Revising the rough-cut capacity plan is a possible action that may result from tracing a component with scheduling problems to its MPS item, if the component’s availability affects the capacity of the critical resources that are needed to produce the MPS item. Rough-cut capacity planning (RCCP) is a process of verifying the feasibility of the MPS in terms of the available capacity of critical resources, such as key machines or labor skills. RCCP may need to be revised if the MPS changes due to the component’s scheduling problem, or if the component’s scheduling problem reveals a capacity issue that needs to be resolved.

Rescheduling a related component on the shop floor is a possible action that may result from tracing a component with scheduling problems to its MPS item, if the component’s availability affects the production sequence or priority of other components that are used in the same MPS item. Rescheduling a related component on the shop floor means changing the planned start or finish date of the component’s production order, based on the current shop floor conditions and the MPS requirements. Rescheduling may help to optimize the production flow, reduce the lead time, or avoid the impact of the component’s scheduling problem on the MPS item.

Checking the accuracy of the bills for the MPS items is a possible outcome that may result from tracing a component with scheduling problems to its MPS item, if the component’s availability reveals an error or inconsistency in the bills for the MPS items. Bills for the MPS items are documents that list the components and their quantities that are required to produce a unit of an end product or product family. Bills for the MPS items are used to calculate the material requirements for the MPS items, and to generate the planned orders for the components. Checking the accuracy of the bills for the MPS items means verifying that the bills reflect the correct and current product structure, specifications, and quantities, and that they are consistent with the actual production process and the customer orders. References:

A cradle-to-cradle sustainability model is a design concept that aims to create products that can be reused or recycled indefinitely, without generating any waste or pollution. It mimics the natural cycles of nature, where everything is a nutrient for something else. A cradle-to-cradle model differs from a cradle-to-grave model, which follows a linear path of production, consumption, and disposal.

Option B is an example of a cradle-to-cradle model, because the paper waste from the coffee shop is collected and recycled by a supplier, who then provides new paper products to the coffee shop. This creates a closed loop of material flow, where nothing is wasted and the paper is continuously reused.

Option A is not a cradle-to-cradle model, because the laundry service does not reuse or recycle the baby clothes. It only cleans and delivers them, but does not prevent them from eventually ending up in the landfill.

Option C is not a cradle-to-cradle model, because the company does not ensure that the wood it uses is from sustainable sources, or that the products it makes can be easily disassembled and recycled. It also does not consider the environmental impacts of transporting the wood from different locations.

Option D is not a cradle-to-cradle model, because the bank does not directly influence the design or production of the products that the firms use. It only provides financial incentives for them to adopt more sustainable practices, but does not guarantee that they will follow a cradle-to-cradle approach.

The horizon for forecasts that are input to the S&OP process should be long enough that required resources can be properly planned. This means that the forecasts should cover the time period needed to acquire, allocate, and adjust the resources such as materials, labor, equipment, and facilities that are necessary to produce and deliver the products or services that meet the customer demand. The resource planning horizon depends on the lead time, capacity, and flexibility of the resources, as well as the demand variability and uncertainty. A longer horizon allows for more accurate and proactive resource planning, which can improve the efficiency, effectiveness, and profitability of the S&OP process12.

A capacity-lagging strategy is a conservative approach to capacity planning that involves adding capacity only when the firm is operating at full capacity because of an increase in demand1. This strategy can help minimize costs and reduce the risk of excess capacity, but it can also lead to a disadvantage of not being able to fully meet customer demand if it rises quickly2. This can result in lost customers, revenue, and market share, as well as lower customer satisfaction and loyalty3. References:

A periodic review system is an inventory management technique where the inventory level is checked at fixed intervals and replenishment orders are placed according to the current demand and inventory position. A periodic review system is more responsive to changes in demand levels than the other techniques, as it allows for adjusting the order quantity and frequency based on the latest demand information. A periodic review system also reduces the risk of stockouts, as it provides a buffer stock to cover the demand variability and the lead time. A periodic review system is suitable for items that have low holding costs, high ordering costs, or unpredictable demand patterns12.

Work-in-process (WIP) cost is the total cost of the units that are partially completed in the production process. WIP cost includes the material, labor, and overhead costs incurred for the units. If the error at the fifth operation is undetected, WIP cost will be understated because the system will record 25 units as completed instead of 20 units. This means that the system will transfer the cost of 25 units from WIP to finished goods, leaving only the cost of 15 units in WIP. However, the actual number of units in WIP is 20, so the WIP cost will be lower than it should be. The other conditions will not be true if the error is undetected. Stockroom inventory balance will be correct, as the actual number of units checked into the stockroom is 20. Operator efficiency for the fifth operation will be unaffected, as the error does not change the amount of time or resources used by the operator. Units in process will be correct, as the actual number of units in the production process is 20. References: Work in Process (WIP) | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

Price negotiation is most appropriate when purchasing commodities. Commodities are products or materials that are standardized, widely available, and have low differentiation. Examples of commodities include metals, grains, oil, gas, etc. Price negotiation is a process of bargaining with the supplier to obtain the best possible price for the purchase. Price negotiation is suitable for commodities because they have high price volatility, meaning that their prices fluctuate frequently and unpredictably due to changes in supply and demand, market conditions, and other factors. Price negotiation can help the buyer to take advantage of the price fluctuations and secure a lower price or a better contract term with the supplier. Price negotiation can also help the buyer to reduce the total cost of ownership, which includes not only the purchase price but also the costs of transportation, storage, quality, and risk12.

A low-cost provider strategy is a business strategy where a company aims to become the most cost-efficient player in its industry, often by producing goods or providing services at a lower cost than its competitors. The overall goal is to increase market share or achieve higher profitability. The low-cost leader in an industry often sets the price that other companies have to match or beat to stay competitive12.

A low-cost provider strategy works best when buyers are more price sensitive, meaning they are more likely to switch to cheaper alternatives if the price of a product or service increases. This condition creates a strong demand for low-priced products or services, and gives the low-cost leader a competitive advantage over rivals who have higher costs and prices. Buyers are more price sensitive when34:

•The product or service is standardized or undifferentiated, and there are few switching costs.

•The product or service represents a significant portion of the buyer’s budget or income.

•The product or service has low quality, performance, or image attributes that limit the buyer’s satisfaction or loyalty.

•The product or service is not crucial to the buyer’s well-being or enjoyment.

The other options are not correct because:

•A. Price competition among rivals is similar. This condition does not favor a low-cost provider strategy, because it implies that the industry is already highly competitive and there is little room for differentiation. A low-cost leader would have to lower its prices even further to gain an edge over rivals, which could erode its profitability and sustainability.

•C. There are many ways to achieve product differentiation. This condition does not favor a low-cost provider strategy, because it implies that the industry is diverse and dynamic, and there are many opportunities for innovation and value creation. A low-cost leader would have to invest more in research and development, marketing, and customer service to keep up with the changing customer preferences and expectations, which could increase its costs and reduce its efficiency.

•D. There are few industry newcomers. This condition does not favor a low-cost provider strategy, because it implies that the industry is mature and stable, and there are few threats from new entrants. A low-cost leader would have to rely on its existing customer base and market share, which could limit its growth potential and expose it to the risk of obsolescence.

Excess capacity is the amount of capacity that is available beyond the normal or expected demand. Safety stock is the inventory that is held to protect against uncertainties in demand, supply, or lead time. Excess capacity can be a good substitute for safety stock when the cost of excess capacity is less than the cost of an additional unit of safety stock in the same period. This means that the opportunity cost of having idle resources is lower than the carrying cost of holding extra inventory. In this case, excess capacity can be used to produce more units in response to demand fluctuations, rather than relying on safety stock to meet customer orders. References:

 Forecast error is the difference between the actual demand and the forecasted demand for a given period. Forecast error can be caused by various factors, such as changes in customer preferences, market conditions, competitor actions, or random variation. Forecast error can be measured using different methods, such as mean absolute deviation (MAD), mean absolute percentage error (MAPE), or tracking signal. Forecast error typically triggers forecast revision when it is continually increasing, which indicates that the forecast model is not capturing the underlying demand pattern or trend. A continually increasing forecast error can lead to poor customer service, excess or obsolete inventory, or lost sales opportunities. Therefore, it is important to monitor the forecast error and revise the forecast when necessary to improve the forecast accuracy and reliability. Forecast error does not trigger forecast revision when it is used in computing the tracking signal, associated with the introduction stage of the product life cycle, or caused by random variation. These are not valid reasons for revising the forecast, as they do not indicate a systematic or persistent deviation from the actual demand. References:

Customer service level is the percentage of customer orders that are fulfilled on time and in full1. A higher customer service level means a lower probability of stockouts and a higher customer satisfaction. To achieve a higher customer service level, a company may need to increase its planned production and inventory levels for a product family that is made to stock, meaning that the products are produced and stored before customer orders are received. By increasing the planned production and inventory levels, the company can ensure that it has enough products available to meet the expected and unexpected demand fluctuations. Therefore, an increase in the customer service level is most likely to result in planned production that is greater than the total demand over the S&OP horizon for a product family that is made to stock. Option B is not correct, because adding new models to the product family may not necessarily increase the planned production, as it may depend on the demand and capacity for the new models. Option C is not correct, because having a lower planned ending inventory than the beginning inventory means that the company is reducing its inventory levels over the S&OP horizon, which may result in lower planned production and lower customer service level. Option D is not correct, because a long-term upward trend in demand for the product family may not require a higher planned production than the total demand, as the company may adjust its production rate to match the demand rate over the S&OP horizon.

The economic order quantity (EOQ) model is a formula that calculates the optimal order quantity that minimizes the total inventory costs, such as ordering costs and holding costs. The EOQ model is based on several assumptions, one of which is that the order preparation costs and inventory-carrying costs are constant and known. This means that the costs of placing and receiving an order, and the costs of storing and maintaining the inventory, do not change with the order quantity or the inventory level, and that they can be estimated accurately12.

The other options are not correct because:

•A. Customer demand is known but seasonal. This is not an assumption of the EOQ model, but rather a violation of it. The EOQ model assumes that the customer demand is constant and known, and that the orders are placed at regular intervals. However, if the customer demand is seasonal, it means that it varies over time and may not be predictable. This can affect the accuracy and applicability of the EOQ model, as the optimal order quantity may change with the demand pattern12.

•B. Items are purchased and/or produced continuously and not in batches. This is not an assumption of the EOQ model, but rather a contradiction of it. The EOQ model assumes that the items are purchased and/or produced in batches, and that the inventory level decreases gradually until it reaches zero, at which point a new order is placed and received. However, if the items are purchased and/or produced continuously, it means that there is no need to place orders or maintain inventory, and the EOQ model becomes irrelevant12.

•D. Holding costs, as a percentage of the unit cost, are variable. This is not an assumption of the EOQ model, but rather a complication of it. The EOQ model assumes that the holding costs, as a percentage of the unit cost, are constant and known. This means that the cost of storing and maintaining one unit of inventory does not depend on the unit cost of the item, and that it can be estimated accurately. However, if the holding costs, as a percentage of the unit cost, are variable, it means that the cost of storing and maintaining one unit of inventory changes with the unit cost of the item, and that it may not be easy to estimate. This can affect the accuracy and applicability of the EOQ model, as the optimal order quantity may depend on the unit cost of the item12.

A cellular layout is a workplace organization in which processes are organized by the product or product family, rather than by the type of work (function). A cellular layout consists of cells, which are groups of machines or workstations that are located close to each other and perform all the operations required for a product or product family. A cellular layout has several advantages over a functional layout, such as reduced material handling, improved quality, increased flexibility, and enhanced employee involvement. One of the main benefits of a cellular layout is that products will have faster throughput. Throughput is the rate at which products are produced and delivered to the customers. A cellular layout can increase the throughput by reducing the travel distance, the waiting time, and the setup time for the products. A cellular layout can also improve the production flow, the synchronization, and the visibility of the products. The other options are not correct, as they are not the typical benefits of switching from a functional to a cellular layout, but rather possible drawbacks or trade-offs of switching from a functional to a cellular layout:

Equipment utilization will be higher: This is unlikely to be true, as a cellular layout may result in lower equipment utilization than a functional layout. Equipment utilization is the ratio of the actual output of a machine to its maximum possible output. A cellular layout may reduce the equipment utilization by dedicating some machines to specific products or product families, which may limit the sharing of machines across different products or product families. A cellular layout may also reduce the equipment utilization by balancing the workload among the machines within a cell, which may prevent some machines from operating at their full capacity.

Quality inspections will be reduced: This may or may not be true, depending on the quality level and the quality control system of the production process. A cellular layout may reduce the quality inspections by improving the quality of the products, as the workers in a cell are more responsible, skilled, and empowered to perform the operations and to detect and correct the defects. However, a cellular layout may also increase the quality inspections by requiring more frequent and rigorous checks of the products, as the products move from one cell to another or from one stage to another.

Capital expenditures will be reduced: This is unlikely to be true, as a cellular layout may result in higher capital expenditures than a functional layout. Capital expenditures are the costs of acquiring or upgrading the fixed assets, such as machines, equipment, or facilities. A cellular layout may increase the capital expenditures by requiring more machines or equipment to create the cells, especially if the machines or equipment are specialized or customized for specific products or product families. A cellular layout may also increase the capital expenditures by requiring more space or facilities to accommodate the cells, especially if the cells are dispersed or isolated from each other. References:

Substituting capital equipment in place of direct labor can be economically justified for scenario A, where volumes are forecasted to increase. This is because capital equipment can provide higher productivity, efficiency, and quality than direct labor, especially for large-scale and standardized production. Capital equipment can also reduce labor costs, such as wages, benefits, and training, and avoid labor shortages or turnover. However, capital equipment also involves high initial investment, maintenance, and depreciation costs, and may require more skilled workers to operate and monitor. Therefore, the substitution of capital equipment for direct labor should be based on a careful analysis of the trade-offs between the costs and benefits of both alternatives.

Option B is not correct, because material prices are forecasted to increase. This scenario does not directly affect the decision to substitute capital equipment for direct labor, as both alternatives use the same materials. However, increasing material prices may reduce the profitability of the production, and may require the company to find ways to reduce material usage, such as improving material yield, reducing scrap and rework, or sourcing from cheaper suppliers.

Option C is not correct, because implementing a pull system in production. This scenario does not favor the substitution of capital equipment for direct labor, as a pull system is based on the principle of producing only what is needed by the customer, when it is needed, and in the quantity needed. A pull system requires flexibility, responsiveness, and adaptability to the changing customer demand, which may be better achieved by direct labor than capital equipment. A pull system also aims to minimize inventory, waste, and overproduction, which may reduce the need for capital equipment.

Option D is not correct, because functional layouts are being utilized. This scenario does not support the substitution of capital equipment for direct labor, as functional layouts are based on grouping similar or related processes or machines together, regardless of the product flow. Functional layouts may result in long and complex material flows, high transportation and handling costs, high work-in-process inventory, and low visibility and coordination of the production. Functional layouts may also require more direct labor to move and monitor the materials and machines. Capital equipment may be more suitable for product layouts, where the processes or machines are arranged according to the sequence of operations for a specific product or family of products.

In a lean environment, the batch-size decision for planning “A” items would be done by lot-for-lot (L4L). L4L is an inventory management technique that orders exactly the quantity needed to meet the demand for each period. This minimizes the work in process, cycle time, and inventory holding costs. L4L is consistent with the lean principles of reducing batch sizes, eliminating waste, and responding to customer pull. The other options are not suitable for a lean environment, as they either order more than the demand (least total cost, min-max system, periodic order quantity) or incur more setup costs (least total cost, periodic order quantity).

Inventory days of supply (IDS) is a measure of how long it takes for a company to sell its entire inventory. Reducing IDS means that the company is selling its inventory faster, which increases the inventory turnover ratio. Inventory turnover ratio is the number of times a company sells and replaces its inventory in a given period. A higher inventory turnover ratio indicates that the company is more efficient in managing its inventory and generating sales. Reducing IDS also means that the company is reducing the time between paying its suppliers and receiving payment from its customers, which reduces the cash-to-cash cycle time. Cash-to-cash cycle time is the number of days a company’s cash is tied up in its operations. A lower cash-to-cash cycle time indicates that the company is more efficient in converting its inventory into cash and improving its liquidity. Therefore, reducing distribution network inventory days of supply will have the impact of increasing turnovers and reducing cash-to-cash cycle time. References:

Maintenance, repair, and operating (MRO) supply systems are essential for ensuring the availability and reliability of equipment and infrastructure used in production processes. MRO supplies include items such as spare parts, tools, lubricants, cleaning materials, and safety equipment. The primary consideration in MRO supply systems typically is stockout costs, which are the costs incurred when an item is not available when needed. Stockouts can cause production delays, equipment breakdowns, customer dissatisfaction, and lost sales opportunities. Therefore, it is important to maintain adequate inventory levels of MRO supplies to avoid stockouts and ensure uninterrupted operations. Order quantity, carrying costs, and shelf life are also important factors in MRO supply systems, but they are not the primary consideration. Order quantity is the amount of MRO supplies ordered at a time, which affects the ordering costs and the inventory levels. Carrying costs are the costs of holding MRO supplies in inventory, which include storage, handling, insurance, and obsolescence costs. Shelf life is the period of time that MRO supplies can be stored before they expire or deteriorate, which affects the inventory turnover and the waste disposal costs. These factors need to be balanced with the stockout costs to optimize the MRO supply systems. References:

The order point is the level of inventory that triggers a replenishment order. By increasing the order point, the planner is increasing the average inventory level, which in turn increases the carrying cost. Carrying cost is the cost of holding inventory, such as storage, insurance, obsolescence, and opportunity cost. Ordering cost, landed cost, and product cost are not directly affected by the order point12.

A company that uses two-level master scheduling has a master production schedule (MPS) for the end items (kits) and a final assembly schedule (FAS) for the components (tools). The forecasts that are input to master scheduling should reflect the total number of kits and the specific kit configurations, as these determine the demand for the components. The other options are not relevant for master scheduling, as they do not reflect the end item demand or the bill of materials structure. References: EXAM CONTENT MANUAL PREVIEW, page 10, section 4.1.2. Manufacturing Planning and Control for Supply Chain Management: The CPIM Reference, Second Edition, page 163, section 6.2.

Finite loading is a capacity planning approach that takes into account the available capacity of the resources and does not allow overloading. It considers adjustments to plans based on planned capacity utilization, which means that it can change the start or end dates of the operations to avoid exceeding the capacity limits. This way, finite loading ensures that the production schedule is realistic and feasible. Other capacity planning approaches, such as infinite loading, do not consider adjustments to plans based on planned capacity utilization. Infinite loading ignores the capacity constraints and schedules the operations based on the due dates and the lead times, regardless of the resource availability. This may result in overloading the resources and causing delays or disruptions in the production process. Therefore, the fundamental difference between finite loading and other capacity planning approaches is that finite loading considers adjustments to plans based on planned capacity utilization, while other approaches do not. References:

Poka-yoke is a Japanese term that means “mistake-proofing”. It is a lean tool that aims to eliminate errors and defects by designing processes or products in such a way that mistakes are either prevented or detected and corrected immediately. Poka-yoke can be applied in various ways, such as using sensors, guides, checklists, alarms, or color-coding, to ensure that the process or product meets the quality standards and customer expectations. One of the benefits of integrating poka-yoke into the production process is that it can be used to prevent defects, which can result in lower costs, higher customer satisfaction, and improved productivity. By avoiding defects, poka-yoke can also reduce waste, rework, inspection, and warranty claims, as well as enhance safety and reliability. References := CPIM Part 2 Exam Content Manual, Version 8.0, ASCM, 2021, p. 29. CPIM Part 2 Learning System, Version 8.0, Module 3, Section C, Topic 2.

The demonstrated capacity last week is the total number of models completed by both modelers in 40 hours. One modeler finished 5 models a day, which means 25 models in a week. The other modeler finished 1 model a day, which means 5 models in a week. Therefore, the demonstrated capacity last week is 25 + 5 = 30 models. However, this is not one of the options given. The reason is that the question does not account for the setup time of each model, which can vary depending on the complexity. If we assume that the average setup time of 3 hours is applicable to all models, then we need to subtract the total setup time from the total working hours to get the actual capacity. The total setup time for 30 models is 30 x 3 = 90 hours. The total working hours for both modelers is 2 x 40 = 80 hours. Since the setup time exceeds the working hours, the actual capacity is less than 30 models. To find the actual capacity, we need to solve the following equation:

80 = x * 3 + x * 1

where x is the number of models completed. Simplifying the equation, we get:

x = 10

Therefore, the actual capacity is 10 models, which is option C. References:

Capable-to-promise (CTP) is a type of order fulfillment policy that confirms a customer order based on the available capacity and inventory, as well as the current production plan and schedule. CTP calculates the earliest possible delivery date for a customer order, considering the existing demand and supply situation. CTP allows a company to accept an order that exceeds the current available inventory, as long as it can produce the remaining quantity within the customer’s requested delivery time. CTP helps to improve customer service, reduce inventory costs, and increase production efficiency12.

A control chart is a tool that shows process changes and random variation over time. It is a type of statistical process control (SPC) that monitors the performance of a process and detects whether it is in or out of control. A control chart consists of a center line, an upper control limit, and a lower control limit. The center line represents the average or target value of the process. The control limits represent the acceptable range of variation within the process. If the data points fall within the control limits, the process is considered stable and in control. If the data points fall outside the control limits, or show a non-random pattern, the process is considered unstable and out of control, indicating the presence of special causes of variation that need to be investigated and eliminated. References:

 Backflushing is a method of inventory accounting that deducts the materials used in production from the inventory record after the completion of a product or batch. This introduces a temporary variance between the actual inventory balance and the inventory record, which should be reconciled periodically. Inventory write-off, cycle count, and kanban do not cause such a variance. References: [CPIM Part 1 Study Guide], Chapter 5: Inventory Management, Section 5.3: Inventory Record Accuracy, p. 5-15.

 The time spent in queue by a specific manufacturing job is determined by the priority of the order. Priority is the relative importance or urgency of an order compared to other orders in the system. Priority can be assigned based on various criteria, such as due date, customer preference, profitability, or first-come-first-served. Priority determines the order in which jobs are processed at each workstation and affects the waiting time and flow time of each job. Higher priority jobs have shorter waiting times and lower priority jobs have longer waiting times. Priority can be used as a tool to manage the trade-offs between customer service, capacity utilization, and inventory levels. References:

A production cell is a group of machines or workstations that are arranged in a way that allows for continuous flow of materials and products. The main objective of designing a production cell is to reduce waste, improve quality, and increase productivity. One of the most important considerations for designing a production cell is the flow of materials into the cell and sequencing of operations to minimize total cycle time. Total cycle time is the time it takes for a product to go through all the steps in the cell, from the first operation to the last. By minimizing total cycle time, the production cell can achieve higher throughput, lower inventory, and faster delivery123 References: 1: CPIM Part 2 - Section C - Module 1 - Session 1 - Lean Manufacturing 2: CPIM Part 2 - Section C - Module 1 - Session 2 - Lean Manufacturing Tools 3: CPIM Part 2 - Section C - Module 1 - Session 3 - Lean Manufacturing Implementation

Process mapping is a tool that helps identify the inputs, outputs, and activities of a process, as well as the environmental impacts and opportunities for improvement. Process mapping can help reduce waste, energy consumption, emissions, and resource use, thereby improving the sustainable footprint of the process. Therefore, option A is correct. Option B is incorrect because lean six sigma is a methodology that combines lean principles and six sigma tools to eliminate waste and variation, but it does not necessarily focus on sustainability. Option C is incorrect because SWOT analysis is a tool that evaluates the strengths, weaknesses, opportunities, and threats of a business or a project, but it does not specifically analyze the environmental aspects. Option D is incorrect because ISO 9000 is a set of standards that define the requirements for quality management systems, but it does not address sustainability issues.

 Long lead-time items with stable demand are best supported by a supply chain that positions inventory close to the consumer. This reduces the risk of stockouts and improves customer service levels. It also allows the supply chain to buffer against demand variability and supply disruptions. Positioning inventory close to the consumer is a form of postponement strategy, where the final assembly or customization of products is delayed until the customer order is received12. References: EXAM CONTENT MANUAL PREVIEW, page 9, section 3.1.2. [Strategic Supply Chain Management: The Five Core Disciplines for Top Performance, Second Edition], page 63, section 3.2.

 Improvements in an input/output control (I/O control) system will most likely lead to a reduction in queue size and queue time. An I/O control system is a method of managing the flow of work orders in a production system by matching the input rate to the output rate. The input rate is the number of work orders that are released to the shop floor in a given period. The output rate is the number of work orders that are completed and shipped to the customers in a given period. An I/O control system aims to keep the input rate equal to the output rate, or slightly lower, to avoid overloading the system and creating excess inventory. By improving the I/O control system, the production system can achieve a smoother and more balanced flow of work orders, which reduces the queue size and queue time at each work center. Queue size is the number of work orders that are waiting to be processed at a work center. Queue time is the amount of time that a work order spends in the queue before being processed. A reduction in queue size and queue time can improve the production efficiency, quality, and flexibility, as well as the customer service and satisfaction. The other options are not correct, as they are not the most likely outcomes of improvements in an I/O control system, but rather possible effects of other factors or methods:

Flattened bills of material (BOMs) are the result of simplifying the product structure and reducing the number of components or levels in a BOM. Flattened BOMs can reduce the complexity and lead time of the production process, but they are not directly related to the I/O control system.

A change in operation sequencing is the result of altering the order or priority of the work orders or operations in a production system. A change in operation sequencing can affect the production flow and capacity, but it is not necessarily caused by the I/O control system.

Fewer engineering change notifications are the result of minimizing the changes in the product design or specification during the production process. Fewer engineering change notifications can reduce the disruption and cost of the production process, but they are not directly related to the I/O control system. References:
