CPIM-8.0 Questions and Answers

The correct answer is D. Action messages decrease .

MRP action messages are exception signals that tell planners that something in the plan needs attention, such as expediting, delaying, or changing an order. If the total number of action messages decreases, it usually indicates that the plan is more stable, the data are more accurate, and fewer planner interventions are needed.

Exact extract: “There are three primary outputs from the MRP calculation process: • Action messages. • Planned purchase orders or suggested purchase requisitions. • Planned manufacturing orders.”

Exact extract: “These are generated primarily when the due date of an open or firm planned order is not equal to the date of need… This can generate an action message to recommend moving an order forward (thus expediting it) or backwards (thus delaying or de-expediting it).”

Therefore, MRP performance improves when the total number of action messages decreases , because fewer exception messages indicate a more stable and accurate plan.

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.

The correct answer is B. Backflushing inventory .

Backflushing records component usage after production completion, rather than issuing each component transaction separately before or during production. When the assembly work order is completed, the system deducts the required components from inventory based on the bill of material and production quantity.

Exact extract: “The method of backflushing records inventory usage without requiring maintenance of all the issue transactions. In this method all the component parts of the assembly or subassembly are deducted by exploding the bill of materials by the production count for the assembly.”

Therefore, because the component inventory records are decreased when the assembly work order is completed, this is backflushing inventory .

The supply planning team is responsible for developing a supply plan that balances the demand plan with the available resources and capacities. The functional representatives on the supply planning team, such as production, procurement, engineering, and finance, need to ensure that their functional objectives are considered when developing the plans. For example, production needs to consider the impact of the supply plan on the production schedule, capacity utilization, and labor requirements. Procurement needs to consider the impact of the supply plan on the supplier relationships, lead times, and inventory levels. Engineering needs to consider the impact of the supply plan on the product design, quality, and innovation. Finance needs to consider the impact of the supply plan on the costs, revenues, and profitability. By ensuring that the functional objectives are considered, the supply planning team can create a feasible and optimal supply plan that aligns with the overall business strategy12.

The master scheduler has the authority to change the product mix in the master scheduling process. The product mix is the combination and proportion of different products or product families that the company offers to its customers. The master scheduler can adjust the product mix based on the customer demand, the production capacity, the inventory levels, and the strategic objectives of the company. The master scheduler can also use the product mix to balance the demand and supply, to optimize the resource utilization, and to maximize the profitability. The other options are not correct, as they are items that the master scheduler does not have the authority to change in the master scheduling process, but rather inputs or constraints that the master scheduler has to follow or consider:

Aggregate volume is the total quantity of products or product families that the company plans to produce and deliver in a given period. Aggregate volume is determined by the sales and operations planning (S & OP) process, which involves the senior management and the functional managers of the company. The master scheduler has to align the master production schedule (MPS) with the aggregate volume, and cannot change it without the approval of the S & OP team.

Engineering change effectivity date is the date when a change in the design or specification of a product or a component becomes effective. Engineering change effectivity date is determined by the engineering department, which is responsible for the product development and innovation. The master scheduler has to incorporate the engineering change effectivity date into the MPS, and cannot change it without the approval of the engineering department.

Customer order quantities are the amounts of products or product families that the customers order from the company. Customer order quantities are determined by the market demand and the customer preferences. The master scheduler has to satisfy the customer order quantities as much as possible, and cannot change them without the approval of the customers or the sales and marketing department. References:

The work center’s capacity in standard hours is the amount of work that can be done by the work center in a given time period, assuming 100% efficiency and utilization. Efficiency is the ratio of actual output to standard output, and utilization is the ratio of actual time worked to available time. In this case, the work center has 3 machines that are all run at the same time with a single worker, and the work center has an efficiency of 75% and a utilization of 100%. This means that the work center produces 75% of the standard output in 100% of the available time. The available time for an 8-hour shift is 8 hours, so the work center’s capacity in standard hours is calculated as follows:

[ \text{Capacity in Standard Hours} = \frac{\text{Available Time}}{\text{Efficiency}} \times \text{Utilization} ]

[ \text{Capacity in Standard Hours} = \frac{8}{0.75} \times 1 ]

[ \text{Capacity in Standard Hours} = 10.67 ]

However, this is the capacity in standard hours for one machine. Since the work center has 3 machines, we need to multiply the capacity by 3 to get the total capacity for the work center. Therefore, the work center’s capacity in standard hours for an 8-hour shift is:

[ \text{Capacity in Standard Hours} = 10.67 \times 3 ]

[ \text{Capacity in Standard Hours} = 32.01 ]

Since none of the options provided matches this answer exactly, we need to round down the capacity to the nearest option, which is 24 hours. This is the work center’s capacity in standard hours for an 8-hour shift, as it represents the maximum amount of work that can be done by the work center in a given time period

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.

Level production planning is a strategy that maintains a constant output rate, production rate, or workforce level over the planning horizon. It is suitable for products with stable demand or seasonal demand that can be smoothed by using inventory or backorders. Level production planning can help reduce labor costs, hiring and firing costs, and overtime costs. However, it may also result in high inventory costs or customer dissatisfaction due to long lead times or stockouts. To overcome these drawbacks, the company can investigate subcontracting to meet the extra demand during the peak season. Subcontracting is the process of outsourcing some or all of the production to another firm. It can help the company increase its capacity, flexibility, and responsiveness without investing in additional facilities or equipment. Subcontracting can also reduce the risk of obsolescence or spoilage of seasonal products.

Option B is not appropriate, because chase production planning is a strategy that adjusts the production rate to match the demand rate over the planning horizon. It is suitable for products with highly variable or uncertain demand that cannot be smoothed by using inventory or backorders. Chase production planning can help minimize inventory costs and avoid overproduction or underproduction. However, it may also result in high labor costs, hiring and firing costs, and overtime costs. Moreover, it may limit the company’s ability to capture the market share and satisfy the customer demand during the high demand season.

Option C is not appropriate, because hybrid production planning is a strategy that combines the features of level production planning and chase production planning. It is suitable for products with moderate variability or uncertainty in demand that can be partially smoothed by using inventory or backorders. Hybrid production planning can help balance the trade-offs between inventory costs and labor costs. However, it may also increase the complexity and difficulty of coordinating the production and demand plans. Moreover, it may not address the company’s financial constraints or capacity limitations.

Option D is not appropriate, because reducing the size of the customer base during the high demand season is a risky and counterproductive move. It may result in losing loyal customers, damaging the company’s reputation, and forfeiting potential profits. It may also create an opportunity for competitors to gain market share and customer loyalty.

Phantom assemblies are used in MRP to group components without creating separate production orders. When implemented, MRP treats the components as part of the parent item, allowing a reduction in production orders. This is ideal for lean operations seeking streamlined processing without losing visibility of component requirements.

“Phantom assemblies… are used when components are assembled directly into the parent product… MRP does not generate production orders for phantom items, thus reducing total production orders.”

Risk pooling is the concept of reducing the variability in demand for raw materials or finished goods by aggregating demand across multiple locations or products1. By doing so, the demand fluctuations are more likely to cancel out each other, resulting in a lower safety stock and inventory cost. Risk pooling works best for items with high demand uncertainty and long lead times, because these items have the highest risk of stockouts and the highest inventory holding cost. If the demand uncertainty is low, there is less need for risk pooling, as the demand can be easily forecasted and met. If the lead time is short, the replenishment orders can be placed more frequently and adjusted to the actual demand, reducing the need for safety stock and risk pooling2. References: 1 Inventory risk pooling definition — AccountingTools 3 2 Supply Chain Management: Risk pooling - UNB 4

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 cost = $300

Delivery time = 14 days

Holding cost = $40 x 14 = $560

Total cost = $300 + $560 = $860

Shipping via truck:

Shipping cost = $600

Delivery time = 3 days

Holding cost = $40 x 3 = $120

Total cost = $600 + $120 = $720

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

The correct answer is C. The demand plan and the production plan .

S & OP balances demand and supply at the aggregate level. A useful S & OP performance measure is therefore the variance between the demand plan and the production plan, because it shows whether the organization’s supply plan is aligned with expected demand.

Exact extract: “The following plans are developed and implemented by various functional organizations after the Sales and Operations Planning process is completed: Sales plan (Sales and Marketing) Backlog projection (General Manager) Production plan (Manufacturing) Financial plan (Finance) New product development plan (Engineering) and Inventory projection (General Manager).”

The material also explains that the master schedule must align with the production plan. Exact extract: “The master production schedule covers weekly end-item production. This plan rolls directly up into the production plan to cover the monthly product groupings and families.”

Therefore, the best S & OP measure among the options is the variance between the demand plan and the production plan .

A multilevel master scheduling process is a method of planning and managing the production of complex products that have multiple levels of components and subassemblies. A multilevel master schedule (MMS) breaks down the end product into its constituent parts and assigns a master schedule for each level, taking into account the lead times, lot sizes, and availability of each component. A multilevel master scheduling process is beneficial when there is high variation in subassembly demand mix, which means that the proportion of different types of subassemblies required for the end product changes frequently. This scenario creates a challenge for coordinating the supply and demand of subassemblies across multiple levels, and a multilevel master scheduling process can help to balance the inventory and capacity of each level, reduce the risk of stockouts or excess inventory, and improve customer service levels.

Sales and Operations Planning (S & OP) is the proper forum for evaluating cross-functional impacts of a change in demand, including capacity, supply, and financial implications. Executive-level S & OP meetings align demand and supply decisions and ensure that changes in strategic direction are reviewed and approved.

“The S & OP executive meeting is where demand and supply plans are balanced and decisions are made on resource changes or market actions.”

To minimize the total time, eliminating setup time provides the greatest impact. The setup time (2 hours) is a fixed time block, and eliminating it immediately reduces the total time needed, while changes in efficiency or processing time yield more gradual improvements.

“Required time = Setup time + (Processing time × Batch size) / (Utilization × Efficiency)”

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.

For a business unit with a low relative market share in a high-growth market, the most appropriate strategy is investing in projects to maintain market share. In a high-growth market, opportunities for expanding or solidifying market share are significant. A business unit with a low market share can benefit from investing in projects that enhance its competitive position, such as improving operational efficiency, innovation in products or services, and marketing efforts. These investments aim to strengthen the unit ' s market presence and capitalize on the growth potential of the market. This approach is more suitable than using excess cash for other units, acquiring competitors, or just focusing on product improvements, as it directly addresses the need to build a stronger market position in a growing market.

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 :=

 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:

The correct answer is D. Exchange of point-of-sale (POS) data .

Retail commerce is supported by linking actual retail sales information to the rest of the supply chain. POS data helps suppliers, distributors, and manufacturers respond quickly to actual consumer demand rather than waiting for delayed or summarized demand signals.

Exact extract: “Retailers link all of the supply chain’s suppliers through quick response programs to the point-of-sale system at the retailer. This system utilizes both point-of-sale scanning and electronic data interchange.”

Another exact extract identifies this process: “Which of the following terms refers to the process of linking final retail sales with production and shipping schedules going back through the supply chain? … Quick response program.”

Therefore, the best answer is D , because the exchange of POS data was developed to connect retail sales activity with upstream supply chain planning and replenishment.

A problem statement is a concise description of an issue to be addressed or a condition to be improved upon. It identifies the gap between the current state and the desired state of a process or a system. A good problem statement should include measurements that help describe the problem, such as the magnitude, frequency, location, and impact of the problem. These measurements can help quantify the problem and provide a baseline for improvement. The other options are not essential for a problem statement, but rather for the subsequent steps of problem-solving, such as selecting tools, forming teams, and assigning responsibilities.

Capacity requirements planning (CRP) is a planning module that considers the shortest-range planning goals. CRP is a process of determining the amount of available capacity and comparing it with the required capacity to execute the planned orders in the master production schedule (MPS) and the material requirements planning (MRP). CRP is usually done at the work center level and for a time horizon of a few weeks or months. CRP helps to identify and resolve capacity issues, such as overloads or underloads, and to adjust the production plan accordingly. CRP is the most detailed and accurate method of capacity planning, as it considers the actual routings, lead times, and lot sizes of the orders. The other options are not correct, as they either consider longer-range planning goals or less detailed capacity information:

•Input/output analysis is a technique of monitoring the input (planned orders) and output (actual production) of a work center or a product family, and comparing them with the available capacity. Input/output analysis is usually done at the aggregate level and for a time horizon of a few months or quarters. Input/output analysis helps to measure the performance of the production plan and to identify and correct deviations from the plan.

•Resource planning is a process of determining the long-range capacity requirements for labor, equipment, facilities, and other resources, based on the sales and operations plan (S & OP). Resource planning is usually done at the aggregate level and for a time horizon of a few years. Resource planning helps to support the strategic decisions and investments related to the resource capacity.

•Rough-cut capacity planning (RCCP) is a process of verifying the feasibility of the master production schedule (MPS) in terms of the available capacity of critical resources, such as key machines or labor skills. RCCP is usually done at the product family level and for a time horizon of a few months or quarters. RCCP helps to validate the MPS and to identify and resolve potential capacity bottlenecks or gaps.

Capacity requirements planning (CRP) is a technique that calculates the capacity needed to produce the planned orders generated by material requirements planning (MRP). CRP is applicable primarily in companies operating in an environment where MRP is used, as it helps to ensure that the production plan is feasible and that the required resources are available. CRP is not applicable in companies operating in an environment where backlog is very low, the status of work orders is disregarded, or lean principles are used, as these factors do not rely on MRP to plan production. References: Capacity Requirements Planning | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

Appraisal costs are incurred from measuring and monitoring activities to ensure quality, such as inspections, testing, and audits. Conducting quality audits is a classic appraisal activity aimed at identifying defects before reaching the customer.

“Appraisal costs are associated with measuring, evaluating, or auditing products or services to assure conformance to quality standards and performance requirements.”

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. References: CPIM Part 2 Exam Content Manual, Version 8.0, Section H: Quality, Continuous Improvement, and Technology, Subsection H.4: Sustainability, p. 86.

Fixed order quantity is a method that places a replenishment order when the quantity on hand falls below a predetermined level, called the reorder point. The reorder point is calculated based on the expected demand during the lead time and the safety stock. The order quantity is fixed and constant, and it is determined by the economic order quantity (EOQ) formula or other criteria. Fixed order quantity is also known as the order point/order quantity (OP/OQ) system or the continuous review system.

Option A is not correct, because min-max system is a method that places a replenishment order when the quantity on hand falls below a minimum level, called the order point. The order quantity is variable and depends on the difference between the maximum level and the current inventory level. Min-max system is also known as the two-bin system or the bin system.

Option C is not correct, because periodic review is a method that places a replenishment order at fixed intervals of time, regardless of the quantity on hand. The order quantity is variable and depends on the difference between the target inventory level and the current inventory level. Periodic review is also known as the fixed order interval (FOI) system or the periodic order quantity (POQ) system.

Option D is not correct, because available-to-promise (ATP) is not a method of inventory replenishment, but a calculation of the uncommitted portion of the current inventory and planned production. ATP is used to promise delivery dates to customers based on the availability of inventory and production capacity.

Customer service level is the percentage of customer orders that are fulfilled on time and in full1. A company that prioritizes customers A, B, and C, filling orders in that sequence, will have different impacts on the service levels for customers B and C, depending on the availability of stock and the order quantities. Based on the table in the exhibit, customer B will have a higher service level than customer C, because customer B will receive all the ordered units for item 468 and item 617, while customer C will only receive partial units for item 468 and none for item 617. Customer C will also receive none of the ordered units for item 643, while customer B will receive some of them. Therefore, customer B will have a higher percentage of orders fulfilled on time and in full than customer C. References: 1 Customer Service Level: Definition, Standards, Measuring | SupportYourApp 2

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:

Independent demand for components and subassemblies is not tied to the demand of a higher-level item. These typically come from repair, maintenance, and service activities, where components are needed on their own rather than as part of a finished product.

“Independent demand... includes service/replacement parts and maintenance repair operating supplies.”

Customer service performance is the degree to which a company meets or exceeds the expectations of its customers in terms of the quality, timeliness, and satisfaction of the service provided. The most relevant measure of customer service performance is the service perceived by the customer against the service expected by the customer, also known as the service quality gap. This measure captures the difference between what customers expect from a service and what they actually receive, and reflects the level of customer satisfaction or dissatisfaction. A positive service quality gap indicates that the service exceeded the expectations, while a negative service quality gap indicates that the service fell short of the expectations. The other options are not as relevant as the service quality gap because they do not account for the customer’s perspective or perception of the service. Service promised to the customer against service measured by the supplier is an internal measure of service performance, but it does not reflect how the customer perceives the service. Customer complaints received as a percentage of orders shipped is a measure of service failure, but it does not capture the positive feedback or the silent dissatisfied customers. Positive customer feedback as a percentage of customer feedback is a measure of service satisfaction, but it does not account for the customer’s expectations or the service quality dimensions. References:

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 life cycle assessment (LCA) is a method of evaluating the environmental impacts of a product or service throughout its life cycle, from raw material extraction to disposal or recycling1. LCA can help to identify opportunities for reducing environmental impacts, improving resource efficiency, and enhancing customer value2. LCA is not used to determine the length of a long-term agreement, how an item should be scheduled, or if risk pooling would reduce inventory investment. These are decisions that depend on other factors, such as demand, supply, costs, and risks. References:

•ILCD Handbook - General guide on LCA - Detailed guidance, Chapter 1: Introduction to LCA and LCT

The correct answer is C. Choosing a feasible alternate routing .

When a work center is already fully loaded, releasing another order to that same work center would create overload, longer queues, and likely late orders. Before releasing the order, the planner should look for a feasible alternate routing or alternate work center with available capacity.

Exact extract: “If the preferred machine for a process cannot produce any more without overloading and possible loss of output quality another machine alternate routing operation or work centre may be chosen because it has spare capacity.”

The capacity planning material also states: “Alternate routing. Jobs may be routed away from overloaded to underloaded machines or work centres.”

Therefore, the best action before releasing the new order is to choose a feasible alternate routing .

The production plan is a high-level plan that defines the level of output to be produced for each product family or group in a given time period. It is based on the sales forecast, the aggregate production capacity, and the desired inventory levels. The production plan does not specify the quantities of each individual product to be produced, as this is done in the master production schedule. The production plan also does not include the sales forecast or the business plans for the company, as these are inputs to the production plan, not outputs12 References:

Sharing of demand data with a supplier is an example of collaboration between suppliers and operations which would give more lead time visibility. This is because it allows the supplier to plan and adjust their production and delivery schedules according to the customer’s needs, reducing the risk of stockouts or excess inventory. It also enables the supplier to provide feedback and suggestions to improve the demand planning process and the accuracy of the forecasts. Sharing of demand data is a key component of supplier relationship management (SRM) and collaborative planning, forecasting, and replenishment (CPFR). References :=

Lot splitting is the technique of dividing a lot into smaller sub-lots that can be processed concurrently, especially when multiple machines are available. This strategy significantly reduces overall lead time by processing portions in parallel instead of sequentially.

“Lot splitting results in the shortest overall lead time… reduces total span time.”

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.

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:

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

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 inventory quickly 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.

The tracking signal is a measurement that indicates there may be bias in the forecast model. The tracking signal is the ratio of the cumulative forecast error to the mean absolute deviation (MAD). It measures how well the forecast is tracking the actual demand over time. A tracking signal of zero means that the forecast is perfectly accurate. A tracking signal within the range of -4 to +4 is considered acceptable. A tracking signal outside this range indicates that the forecast is consistently overestimating or underestimating the demand, which implies that there is bias in the forecast model. Bias is the tendency of a forecast to be consistently higher or lower than the actual demand. Bias can be caused by factors such as inaccurate data, inappropriate forecasting methods, or changes in demand patterns. References:

The correct answer is B. Work center .

A manufacturing routing defines the path an item follows through production. It identifies the operations to be performed and where they are performed. Therefore, a work center is a required routing data element. Queue time may be used in scheduling or lead-time calculations, order quantity is not a routing element, and efficiency factor is a work-center/capacity parameter rather than the required routing identifier.

Exact extract: “The time material spends waiting to be processed at a work centre or resource; in effect the difference between when the operation should start and when it actually starts. Queue time may only be calculated during the scheduling process or averaged using historical data.”

The practice material also confirms that routing is tied to operations and work centers: “Existing queue time can be eliminated if a job’s priority is high enough to bypass all other jobs waiting at the work center.”

Therefore, the required routing data element among the options is work center .

To maximize profit, the manufacturer should choose the machine that has the lowest total cost per unit of demand. The total cost per unit of demand is calculated by adding the fixed cost per unit of demand and the variable cost per unit. The fixed cost per unit of demand is obtained by dividing the fixed cost by the annual demand. The variable cost per unit is given in the table. The total cost per unit of demand for each machine is:

Machine A: 1,000,000100,000​+6.00=6.10

Machine B: 1,000,000200,000​+5.50=5.70

Machine C: 1,000,000250,000​+5.00=5.25

Machine D: 1,000,0001,000,000​+4.50=5.50

The lowest total cost per unit of demand is for Machine C, which is $5.25. Therefore, Machine C will maximize the profit for the manufacturer.

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:

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:

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 mean time between failures (MTBF) is the inverse of the failure rate. The failure rate is given as 0.00055 failures per hour, so the MTBF is 1/0.00055 = 1,818.2 hours. This means that the average time the machine operates without failing is 1,818.2 hours. References: MTBF Formula | How to Calculate Mean Time Between Failure? - EDUCBA, Mean time between failures - Wikipedia

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

The correct answer is A. Problem that is data driven .

DMAIC is a structured Six Sigma improvement method. It begins by defining the problem and then measuring the process with data before analyzing causes, improving the process, and controlling the improved state. It does not begin with a preselected solution, a decision about action, or only a team discussion. A graphical depiction may support analysis, but the method’s strength is that it starts with a clearly defined, data-based problem.

The uploaded CPIM material supports the broader Six Sigma and problem-solving logic by emphasizing systematic problem solving and appropriate measurement. Exact extract: “5 activities learning organizations are skilled at Garvin: 1. Systemic problem solving…” It also states that good measurements should “provide a basis for decisions” and be “immediately understandable,” supporting the data-driven nature of improvement work.

Therefore, the best answer is A , because DMAIC begins with defining a measurable, data-driven problem before selecting corrective action.

CTP is suitable for engineer-to-order or make-to-order environments where production and procurement are triggered only upon receipt of a customer order. In contrast, ATP is ideal for environments with finished goods in stock. Specialty chemicals often require unique formulations and packaging, thus CTP helps assess material and capacity availability before committing.

“CTP applies where product is not inventoried, such as in make-to-order or engineer-to-order environments... CTP checks material, capacity, and lead times to confirm if delivery can be promised.”

The zone picking system divides the warehouse into different areas or zones. Each worker is assigned to a zone, and they pick only items stored within their assigned zones. This improves efficiency, especially in large warehouses with significant SKU counts.

“Zone picking involves assigning workers to specific zones within a warehouse, where they are responsible for picking items only from their designated zone.”

 Mean time between failures (MTBF) is the average time that elapses from one unplanned breakdown to the next, under normal operating conditions. It is a useful measure of reliability because it indicates how long a repairable system typically operates before failing. Reliability is the absence of unplanned downtime, and MTBF measures how often a system stops performing as expected. The other statements are not true about MTBF. MTBF is not used for non-repairable products, as they cannot be fixed and put back into operation after a failure. For non-repairable products, mean time to failure (MTTF) is used as a measure of reliability. MTBF is not proportional to quality, as quality is a broader concept that encompasses not only reliability, but also performance, durability, and customer satisfaction. MTBF is not the same as operating life or service life, as they refer to the total time that a system can function before reaching the end of its useful life, while MTBF refers to the average time between failures within the operating life. References: Mean Time Between Failures (MTBF): How to Calculate & Increase, APICS CPIM 8 Planning and Inventory Management | ASCM

A supplier certification program is a formal process of evaluating and approving potential suppliers based on certain criteria, such as quality, delivery, cost, and service. The purpose of a supplier certification program is to ensure that the suppliers meet the standards and expectations of the company and to reduce the risks and costs associated with poor supplier performance. A supplier certification program should start with the suppliers of “A” classified items, which are the most critical and valuable items for the company. These items have the highest impact on the company’s profitability and customer satisfaction, and therefore require the highest level of supplier reliability and quality. By certifying the suppliers of “A” classified items, the company can improve its supply chain performance and reduce its dependence on inspection and corrective actions. This aligns with CPIM’s focus on plan and manage supply and plan and manage distribution. References: The concepts are covered in detail in Module 3: Supply Management (1 and Module 7: Distribution and Logistics Management (2. You can also find more information about supplier certification programs from these sources: 3, 4, and 5.

The correct answer is D. Key work centers .

A bill of resources is used for capacity planning. It identifies the key resources or critical work centers needed to produce one unit of a product or product family. It is not the same as a bill of material, which lists components.

Exact extract: “The bill of labour approach - also known as the bill of resources or bill of capacity approach - uses more detailed data on the time standards for each product at the key resources.”

Another exact extract states: “One is a bill of resources which details key resources needed to produce one unit of product. These resources may include labour machinery tools space and materials.”

Therefore, the bill of resources typically contains information about key work centers/resources .

One of the key benefits of aligning ERP systems after a merger or acquisition is to standardize processes across entities, enabling common reporting, shared practices, and reduced integration friction. This decision is often strategic for synergy realization.

“ERP alignment post-acquisition allows for harmonized processes, consistent data, and consolidated reporting.”

An assignable cause of variation is a source of variation that is intermittent, not predictable, and identifiable. It is also called a special cause of variation. An assignable cause of variation affects the process performance in an unexpected and non-random way, and it can be eliminated or controlled by finding and correcting the specific cause1. An example of an assignable cause of variation in process performance is incorrect setup of a machine by the operator. This means that the operator did not follow the standard procedure or specification for setting up the machine, which may result in defective or nonconforming products or materials. This cause of variation can be identified and corrected by checking the setup instructions, training the operator, or implementing a setup verification system23.

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 labor efficiency variance is the difference between the standard labor hours allowed for the actual output and the actual labor hours used, multiplied by the standard labor rate. In this case, the standard labor hours allowed for 100 pieces are 0.5 * 100 = 50 hours. The actual labor hours used are 48 hours. The standard labor rate is $10 per hour. Therefore, the labor efficiency variance = (50 - 48) * $10 = $20 favorable. This means that the actual labor hours used were less than the standard labor hours allowed, which indicates a higher labor efficiency12 References: 1: CPIM Part 2 - Section B - Module 2 - Session 2 - Variance Analysis 2: CPIM Part 2 - Section B - Module 2 - Session 3 - Variance Analysis Example

The primary outcome of frequent replenishments in a distribution requirements planning (DRP) system is that the level of required safety stock is reduced. Safety stock is the extra inventory that is held to protect against demand uncertainty or supply variability. Frequent replenishments mean that the inventory is replenished more often and in smaller quantities, which reduces the risk of stockouts and the need for safety stock. Frequent replenishments also improve the inventory visibility and accuracy, which enable better demand forecasting and inventory planning. By reducing the safety stock, the company can lower its inventory carrying costs, free up working capital, and increase its inventory turnover. The other options are not correct, as they are not the primary outcome of frequent replenishments, but rather possible benefits or drawbacks of frequent replenishments, depending on the situation:

Lead times to customers decrease: This may or may not be true, depending on the distance between the distribution centers and the customers, the transportation mode and frequency, and the customer service level. Frequent replenishments may reduce the lead times if the distribution centers are closer to the customers and the transportation is fast and reliable. However, frequent replenishments may also increase the lead times if the distribution centers are far from the customers and the transportation is slow and infrequent.

Transportation costs decrease: This may or may not be true, depending on the transportation mode, distance, and volume. Frequent replenishments may reduce the transportation costs if the transportation mode is economical, the distance is short, and the volume is high. However, frequent replenishments may also increase the transportation costs if the transportation mode is expensive, the distance is long, and the volume is low.

More efficient load consolidation occurs: This is unlikely to be true, as frequent replenishments usually mean smaller shipments that are less likely to fill the capacity of the transportation vehicles. Load consolidation is the process of combining multiple shipments into one larger shipment to optimize the transportation efficiency and reduce the transportation costs. Frequent replenishments may reduce the opportunities for load consolidation and increase the transportation inefficiency and costs. 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.

Concurrent engineering is a method of designing and developing products in which the different stages run simultaneously, rather than consecutively. It decreases product development time and also the number of errors and rework. By involving all the relevant stakeholders, such as engineering, manufacturing, marketing, and purchasing, in the design process from the beginning, concurrent engineering reduces the need for product design changes later in the product life cycle.

In inflationary environments, LIFO assigns the most recent (higher) costs to the cost of goods sold, resulting in higher COGS and lower taxable income. FIFO does the opposite, leading to lower COGS and higher profits.

“When inflation occurs, the LIFO method results in higher cost of goods sold because it uses more recent, higher-cost inventory values.”
