CPIM-8.0 Certified in Planning and Inventory Management (CPIM 8.0) Questions and Answers

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.

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.

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.

An effective approach to projecting requirements for materials with long lead times is to initiate a multilevel master schedule. A multilevel master schedule is a detailed plan that shows the quantities and timing of the end items and all of their components at each level of the bill of materials (BOM). By using a multilevel master schedule, a planner can determine the requirements for materials with long lead times and place orders in advance to avoid shortages or delays. A phantom bill of materials (BOM) is a temporary grouping of components that are used in the production of a parent item, but do not exist as a separate item in inventory. A phantom BOM is not an effective approach to projecting requirements for materials with long lead times, as it does not reflect the actual demand for the components. Increasing the level of safety stock is a way of mitigating the risk of uncertainty in demand or supply, but it is not an effective approach to projecting requirements for materials with long lead times, as it increases the inventory carrying costs and does not address the root cause of the problem. Decreasing the planning horizon is the opposite of an effective approach to projecting requirements for materials with long lead times, as it reduces the visibility and accuracy of the forecast and increases the likelihood of stockouts or excess inventory. 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

Reducing replenishment lead times will result in lower inventory levels because it means that the time between placing an order and receiving the goods is shorter. This reduces the need to hold excess inventory to cover the uncertainty and variability of demand and supply. Reducing replenishment lead times can also improve customer service levels, as orders can be fulfilled faster and more reliably. Level loading the master production schedule (MPS), increasing customer service level, and decentralizing inventory locations are all actions that will increase inventory levels, as they require more inventory to buffer against fluctuations in demand and supply, and to ensure availability at multiple locations. References: Inventory Management: Lead Time Reduction, APICS CPIM 8 Planning and Inventory Management | ASCM

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).

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 indetail in Module 1: Business Planning and Strategy (1 and Module 2: Demand Management (2.

Given the bill of material (BOM) information, we can calculate the weekly gross requirement of component F by considering the independent requirements of Component A and B. For Component A, there is no direct requirement for Component F. For Component B, which has an independent requirement of 20 pcs per week, each requires 4 pcs of Component F according to its BOM. So, thetotal weekly gross requirement for Component F due to Component B is 204 = 80 pcs. Additionally, each piece of Component A requires 2 pieces of Component C according to its BOM and has an independent requirement of 10 pcs per week; hence requiring a total of 20 pieces of component C per week. Each piece of component C in turn requires 4 pieces of component F according to its BOM; hence requiring a total weekly gross requirement for component F due to component A is: 204 =80 pcs. Adding both gives us a total weekly gross requirement for component F as:80+80=160pcs. References:

Available-to-promise (ATP) is the uncommitted portion of a company’s inventory and planned production maintained in the master schedule to support customer-order promising. ATP is calculated by subtracting the customer orders and forecast from the projected on-hand inventory. The projected on-hand inventory is calculated by adding the beginning inventory and the master production schedule (MPS) and subtracting the customer orders.The largest customer order that could be accepted for delivery at the end of week 3 without making changes to the MPS is the ATP at the end of week 3. To calculate the ATP, we need to fill in the projected on-hand inventory for each week using the given information:

Table

The ATP at the end of week 3 is 54, which means that the company can promise 54 units of inventory to customers without changing the MPS. However, the question asks for the largest customer order that could be accepted, which means that we need to consider the existing customer orders as well. The customer orders for week 3 are 10, which means that the company has already committed 10 units of inventory to customers. Therefore, the largest customer order that could be accepted for delivery at the end of week 3 is 54 + 10 = 64 units. However, this is not one of the options given in the question. The closest option that is less than or equal to 64 is 61, which is option C12 References: 1: CPIM Part 1 - Section A - Module 1 - Session 4 - Master Scheduling 2: CPIM Part 1 - Section A - Module 1 - Session 5 - Available to Promise

 The production supervisor is the most appropriate person to send the information about the overage in actual run time for one operation. The production supervisor is responsible for overseeing the execution of the production plan and ensuring that the operations are performed efficiently and effectively. The production supervisor can review the actual run time data and compare it with the planned run time, identify the possible causes of the overage, and take corrective actions if needed. The production supervisor can also explain the overage to the cost accountant and other stakeholders, such as the product manager, the quality manager, and the engineering manager, and provide feedback for improving the planning and routing of the operation. References:

The probability of stocking out is the likelihood that the demand for an item will exceed the available inventory during a given period. It is one of the criteria used to determine safety stock in a distribution center (DC), as safety stock is inventory that is carried to protect against forecast errors and fluctuations in demand or supply. The higher the probability of stocking out, the more safety stock is needed to avoid customer dissatisfaction and lost sales. The other criteria are not directly related to safety stock. Economic order quantity (EOQ) is the order quantity that minimizes the total inventory holding and ordering costs. Seasonal index value is a measure of how demand varies according to different seasons or periods. Alpha factor level is a parameter used in exponential smoothing to adjust the forecast based on the error between the actual and forecasted demand. References: Safety Stock: A Contingency Plan to Keep Supply Chains Flying High, APICS CPIM 8 Planning and Inventory Management | ASCM

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.

A push system is a production system that relies on forecasts and schedules to plan the production and distribution of goods and services. A pull system is a production system that responds to actual customer demand and signals to trigger the production and distribution of goods and services. A transition from a push system to a pull system requires a change in the mindset and the processes of the organization, as well as the adoption of new tools and techniques to enable a demand-driven production system12.

One of the tools that is commonly used in a pull system is kanban, which is a visual signal that indicates the need for replenishment of materials or products. Kanban cards are attached to standardized containers that hold a fixed amount of inventory. When a container is empty, the kanban card is sent back to the upstream process as a signal to produce more. This way, the inventory level is controlled by the actual consumption of the downstream process, and the production is synchronized with the demand13.

One of the actions that hinders the transition from a push system to a pull system is using work orders as a backup. Work orders are documents that authorize the production of a certain quantity of a product or a service, based on a forecast or a schedule. Work orders are typical of a push system, as they are not triggered by the actual customer demand, but by the planned production. Using work orders as a backup means that the organization is not fully committed to the pull system, and still relies on the push system to ensure the availability of inventory. This can create confusion, inconsistency, and inefficiency in the production system, as well as increase the inventory holding costs and the risk of obsolescence1 .

Therefore, using work orders as a backup is the correct answer, as it is an action that hinders the transition from a push system to a pull system. The other options are actions that support the transition, as they are aligned with the principles and practices of a pull system.

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.

A reduction in purchased lot sizes means ordering smaller quantities of materials more frequently. This reduces the average inventory level and the carrying cost of inventory. However, it also increases the frequency of orders and the ordering cost. The reorder point (ROP) is the level of inventory that triggers a new order, and it depends on the demand rate, the lead time, and the safety stock. The ROP is not affected by the lot size, unless the demand or the lead time changes. The setup time is the time required to prepare a machine or a process for production, and it is not related to the purchased lot size. References: EXAM CONTENT MANUAL PREVIEW, page 14, section 6.1.2. Manufacturing Planning and Control for Supply Chain Management: The CPIM Reference, Second Edition, page 433, section 12.4.

A level production strategy is a manufacturing strategy where a company produces a fixed number of products at a fixed rate1. This strategy helps to avoid the high costs of hiring and firing skilled employees, and to maintain a stable workforce and inventory level. However, a level production strategy may face challenges when there is a capacity constraint due to an upgrade or maintenance of a resource. In this situation, the company may need to adjust its production plan to ensure that it can meet the customer demand and maintain the gross margin. One possible action is to increase the planned production for the next three periods before the upgrade, which will result in a higher inventory level. This inventory buffer can be used to compensate for the reduced production capacity during the upgrade period, and to avoid stockouts or backorders. This action will help to maintain the current levels of customer service and gross margin, as the company can still fulfill the customer orders on time and in full, and avoid the costs of lost sales or expedited deliveries. Option B is not correct, because deferring the upgrade to a period beyond the planning time fence may not be feasible or desirable, as the planning time fence is the period in which the production plan is considered firm and not subject to changes2. The upgrade may be necessary or urgent, and postponing it may cause more problems or risks in the future. Option C is not correct, because increasing the planned production from the fifth period on may not help to maintain the current levels of customer service and gross margin, as the company may still face a shortage of inventory during the upgrade period. Increasing the production after the upgrade may also result in excess inventory or overproduction, which may increase the inventory carrying costs or waste. Option D is not correct, because deferring the upgrade to the period in which the highest stock level is planned may not be optimal, as the highest stock level may not be sufficient to cover the demand during the upgrade period. Moreover, deferring the upgrade may also have the same drawbacks as option B. References: 1 Guide to Level Production Strategy - Welp Magazine 3 2 Planning Time Fence | SAP Help Portal 4

Mixed-model scheduling is a technique that allows multiple products to be produced on the same assembly line without changeovers, and then sequences those products in a way that smoothes the demand for upstream components12. In this case, the company is using mixed-model scheduling to produce three different products (A, B, and C) on the same line, and then alternating them in a pattern that minimizes the variation in the workload and the inventory levels. The other options are not correct because:

•Matrix scheduling is a technique that assigns tasks to workers based on their skills and availability3.

•Synchronized scheduling is a technique that coordinates the production and delivery of materials and components to match the demand of the final assembly4.

•Line balancing is a technique that distributes the workload evenly among the workers or machines on a production line5.

Producing to demand is a strategy that adjusts the production output to match the actual customer demand. This strategy is most appropriate during times of highly fluctuating demand, as it can reduce the inventory carrying costs and avoid overproduction or underproduction. Producing to demand can also improve customer satisfaction and responsiveness, as well as reduce waste and obsolescence. However, producing to demand requires a flexible and adaptable workforce that can easily change its capacity and skills to meet the changing demand patterns. The other options, producing to backorders, producing at a constant level, and producing to the sales forecast, are not as effective as producing to demand during times of highly fluctuating demand, as they can result in higher inventory costs, lower customer service, and lower profitability. References:

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.”

Demonstrated capacity is the actual output achieved by a resource or a system over a period of time, such as a day, a week, or a month. It is determined from actual results, such as production records, time studies, or historical data. Demonstrated capacity reflects the past performance, not the future load, of a resource or a system. It may be lower or higher than the rated capacity, which is the theoretical or design capacity of a resource or a system. Demonstrated capacity considers utilization and efficiency factors, such as machine availability, operator skills, product mix, quality issues, or maintenance schedules, that affect the actual output. References:

 An order winner is a product attribute that influences customers to choose one product over another. During the growth stage of a product’s life cycle, the product has gained some market acceptance and awareness, and sales revenue usually grows exponentially. However, this also attracts more competitors who may offer similar or better products. Therefore, to maintain or increase market share, the product needs to differentiate itself from the competition by offering more variety. Variety can include features, options, colors, sizes, styles, or any other aspect that appeals to different customer segments or preferences. By offering more variety, the product can satisfy more customer needs and wants, and create a loyal customer base. Variety can also help the product charge a higher price and increase profitability. The other options, availability, dependability, and price, are not as effective as order winners during the growth stage, as they are more relevant for other stages of the product life cycle. Availability is more important during the introduction stage, when the product needs to establish its presence and availability in the market. Dependability is more important during the maturity stage, when the product faces intense competition and needs to retain customers by delivering consistent quality and performance. Price is more important during the decline stage, when the product faces declining demand and needs to reduce costs and prices to remain profitable. References:

The sales and operations plan (S&OP) is the most appropriate level to adjust when a major new customer is received from sales. The S&OP is a cross-functional process that aligns the demand and supply plans with the business strategy and financial goals. It also provides the basis for the masterproduction schedule (MPS), which is a more detailed and disaggregated plan for specific products or families. Adjusting the production volume or the forecast would not be sufficient to account for the impact of the new customer on the overall business objectives and resources. References:

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:

Increasing safety stock to improve customer fill rate would result in a decrease in inventory turns. Inventory turns, or inventory turnover, is a metric measuring how fast the inventory is replaced over time. It is calculated as the cost of goods sold divided by the average value of inventory during the period covered1. A higher inventory turnover ratio indicates that the company sells its inventoryquickly and efficiently, while a lower ratio implies that the company holds too much inventory or has difficulty selling it. Safety stock is an extra quantity of a product stored in the warehouse to prevent an out-of-stock situation. It serves as insurance against fluctuations in demand, longer lead times, and price fluctuations2. Increasing safety stock means increasing the average value of inventory, which lowers the inventory turnover ratio. This also increases the inventory carrying costs, such as storage, insurance, taxes, and obsolescence. Therefore, there is a trade-off between increasing safety stock to improve customer fill rate and decreasing inventory turns to reduce inventory costs3.

Changing the due dates of open orders is a common practice to cope with demand fluctuations, capacity constraints, or material shortages. However, it can have a negative effect on the stability and reliability of the schedule, causing “nervousness”. Nervousness is the tendency of the schedule to change frequently and significantly due to minor changes in inputs or parameters. Nervousness can result in increased costs, reduced efficiency, lower quality, and lower customer satisfaction. To avoid or reduce nervousness, some strategies are: using time fences, freezing the schedule, aggregating the demand, and using safety stock or safety time. References :=

Total productive maintenance (TPM) is a holistic approach to equipment maintenance that strives to achieve perfect production: no breakdowns, no small stops or slow running, no defects, and no accidents. TPM emphasizes proactive and preventative maintenance to maximize the operational efficiency of equipment. It blurs the distinction between the roles of production and maintenance by placing a strong emphasis on empowering operators to help maintain their equipment. The implementation of a TPM program creates a shared responsibility for equipment that encourages greater involvement by plant floor workers. In the right environment, this can be very effective in improving productivity and quality12. One of the eight pillars of TPM is planned maintenance, which aims to reduce the frequency of breakdowns and minimize the impact of failures on production. Planned maintenance involves scheduling maintenance activities based on the actual condition of the equipment, rather than on a fixed time interval. This reduces the risk of over-maintenance or under-maintenance, and optimizes the use of resources. Planned maintenance also involves improving the maintainability and reliability of the equipment, by identifying and eliminating the root causes of failures, and implementing design changes or modifications34.

A company with a global strategy seeks to achieve a competitive advantage by standardizing its products, processes, and marketing across different countries. It leverages economies of scale and scope, as well as global brand recognition, to gain market share and profitability. It does not adapt to local preferences or conditions, but rather imposes a uniform approach to all markets. References: EXAM CONTENT MANUAL PREVIEW, page 6, section 1.1.2. Strategic Supply Chain Management: The Five Core Disciplines for Top Performance, Second Edition, page 19, section 1.2.

 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:

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.

An X-bar chart is a type of control chart that is used to determine the average value of a group of units. It is also known as a mean chart. It plots the sample means of subgroups of units over time and compares them with the center line and the control limits. An X-bar chart is useful for monitoring the central tendency of a process and detecting any shifts or trends in the process mean. It is often used in conjunction with an R-chart, which measures the subgroup variation. 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.

Proximity to suppliers would be classified as a cost factor in preparing for a facility location decision. Cost factors are the expenses associated with operating a facility in a specific location, such as labor, materials, utilities, taxes, and transportation. Proximity to suppliers can affect the cost of inbound transportation, inventory holding, and quality control. Choosing a location that is close to suppliers can reduce these costs and improve the efficiency and reliability of the supply chain. References:

The cost to deliver the order consists of two components: the shipping cost and the holding cost. The shipping cost is the amount paid to the transportation mode for moving the order from the origin to the destination. The holding cost is the amount incurred for storing the order until it is delivered to the customer. The holding cost depends on the delivery time, which is the number of days it takes for the order to reach the customer. The longer the delivery time, the higher the holding cost. The shipping cost and the holding cost for each transportation mode are calculated as follows:

• Shipping via rail:
• Shipping via truck:

Therefore, the cost to deliver the order via rail is $860, and the cost to deliver the order via truck is $720. References: Transportation Costing | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

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.

Substitute products are components of an organization’s immediate industry and competitive environment. They are products or services that can satisfy the same customer needs or wants as the organization’s offerings, but are provided by different industries or markets. Substitute products can affect the demand, price, and profitability of the organization’s products, and require the organization to monitor and respond to the changes in customer preferences and competitive pressures. Political factors, interest rates, and sociocultural forces are examples of macroenvironmental factors, which are broader and more general forces that affect the organization and its industry, but are not directly related to its competitors or customers. References :=

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:

A bill of resources is a tool that lists the capacity requirements for each work center or resource group based on the planned production quantities. It is used to evaluate the impact that a production plan has on capacity by comparing the available capacity with the required capacity. A bill of resources can also help identify capacity bottlenecks, excess capacity, and alternative resources. A demand time fence(DTF) is a tool that defines the period of time in which the master production schedule (MPS) is frozen and cannot be changed by customer orders. A product routing is a tool that defines the sequence of operations and work centers required to produce a product. A safety capacity is a tool that provides a buffer against demand and supply uncertainty by adding extra capacity to the planned capacity. These tools are not directly used to evaluate the impact that a production plan has on capacity, although they may affect the capacity planning process. References: Bill of Resources | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

The total landed cost is the sum of all the costs associated with buying a quantity larger than immediately needed, including the cost of the product, the custom fees, the freight, and the warehouse rent. Based on the table, the total landed cost can be calculated as follows:

Landed cost = material cost + custom fees + freight + warehouse rent Landed cost = $500 + $125 + $700 + $200 Landed cost = $1,525

Therefore, the correct answer is D. $1,525. The other options are not correct, as they either omit some of the costs or use incorrect values. The total landed cost reflects the direct costs only to move the product from the factory floor to the customer. It is an important supply chain KPI in inventory management, as it helps to determine the optimal order quantity, pricing, and profitability of the products12. References:

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.

Process engineers are responsible for designing, implementing, controlling, and optimizing industrial processes, especially continuous ones such as the production of petrochemicals1. One of the decisions that process engineers would most likely make is the routing sequence, which is the order of operations or activities that are performed on a product or material as it moves through the production process2. The routing sequence affects the process performance, efficiency, quality, and cost, and it requires careful planning and analysis by the process engineers. Option A is not correct, because lead times are the time intervals between the initiation and completion of a process or a project3. Lead times are influenced by many factors, such as demand, capacity, inventory, scheduling, and supply chain management, and they are not solely determined by the process engineers. Option B is not correct, because production capacity is the maximum amount of output that a process or a system can produce within a given period of time4. Production capacity depends on the availability and utilization of resources, such as materials, labor, equipment, and facilities, and it is not only decided by the process engineers. Option C is not correct, because product reliability is the probability that a product will perform its intended function without failure for a specified period of time under specified conditions5. Product reliability is affected by many aspects, such as product design, quality control, testing, maintenance, and customer feedback, and it is not the sole responsibility of the process engineers.

In a rapidly changing business environment, a primary advantage of an effective customer relationship management (CRM) program is earlier identification of shifts in customer preferences. CRM is a strategy that focuses on building and maintaining long-term relationships with customers by understanding their needs, preferences, and behaviors. CRM enables organizations to anticipate and respond to changes in customer demand, improve customer satisfaction and loyalty, and increase profitability and competitiveness. CRM also helps organizations to segment and target customers based on their value and potential, and to customize products and services accordingly. CRM involves the use of various tools and techniques, such as data collection and analysis, communication channels, feedback mechanisms, and loyalty programs. References:
