CPIM-Part-2 Certified in Planning and Inventory Management(Part 2) Questions and Answers

Available-to-promise (ATP) is a business function that provides a response to customer order inquiries, based on resource availability1. It generates available quantities of the requested product, and delivery due dates. Therefore, ATP supports order promising and fulfillment, aiming to manage demand and match it to production plans1.

The most appropriate course of action when the customer requests an order of 100 units in Period 1, but the ATP is only 85 units, is to promise the 85 units in Period 1 and the remaining 15 units in the next possible ATP period. This way, the customer can receive a partial fulfillment of their order as soon as possible, and the rest of their order when more inventory becomes available. This approach also avoids overpromising or underdelivering, which can damage customer relationships and satisfaction.

The other options are not appropriate, because they either violate the master schedule, ignore the component availability, or disadvantage another customer. Increasing the MPS quantity in Period 1 by 15 units may not be feasible or desirable, because it may disrupt the production plan, increase costs, or create capacity issues. Promising the 100 units, and then checking on component availability may result in a failure to deliver, if the components are not available or sufficient. Promising the 100 units by removing 15 units from another customer’s order with a smaller revenue value may be unethical or unfair, and may also cause dissatisfaction or complaints from the other customer.

Shop backlogs are the amount of work that has been ordered but not yet completed by a production facility1. Shop backlogs remain constant when the work input, which is the rate of incoming orders, equals the work output, which is the rate of finished products2. This means that the production facility is able to match the demand and supply of its products, and maintain a steady level of backlog. This can indicate that the production facility is operating efficiently and effectively, and has a stable market position.

The other options are not correct. Forecasts are updated on the basis of the longest lead time item means that the production facility uses the item that takes the longest time to produce as a reference for planning its future production3. This may help the production facility to avoid underestimating its capacity or overcommitting its resources, but it does not guarantee that the shop backlogs will remain constant, as it depends on the actual demand and supply of its products. Capacity is assumed to be infinite means that the production facility does not consider anylimitations or constraints on its ability to produce its products. This may help the production facility to simplify its production planning and scheduling, but it does not reflect the reality of its operations, and may lead to unrealistic expectations or poor performance. Shop orders are released at a steady rate means that the production facility releases a fixed number of orders to its shop floor at regular intervals. This may help the production facility to smooth out its production flow and reduce variability, but it does not ensure that the shop backlogs will remain constant, as it depends on the actual work input and output.

An effective process to create meaningful change begins with identifying and discussing a past crisis, a potential crisis, or major opportunities. This step is important because it helps to create a sense of urgency and motivation for the change, as well as to clarify the vision and goals of the change1. A past crisis can be used as a learning opportunity to analyze what went wrong and how to prevent it from happening again. A potential crisis can be used as a warning signal to anticipate and prepare for the possible challenges and risks. A major opportunity can be used as a catalyst to seize the competitive advantage and create value for the organization and its stakeholders2.

The other options are not the best ways to start an effective process to create meaningful change. Reviewing financial outcomes and metrics over the last 4 quarters year-over-year may provide some insights into the performance and profitability of the organization, but it may not reveal the underlying causes or drivers of the change, or the future trends and scenarios that may affect the organization3. Refreshing corporate strategy to align with current marketplace realities for your industry may be a necessary step in the change process, but it may not be sufficient to generate buy-in and commitment from the people who are involved in or affected by the change4. Using consultants to provide in-depth analysis of current management opportunities may be a helpful way to obtain external perspectives and expertise, but it may not ensure that the change is aligned with the organization’s culture, values, and capabilities5.

The priority rule that is most consistent with the objective of meeting due dates is slack time per operation. Slack time per operation is a priority rule that assigns a priority index to each job based on the ratio of the remaining slack time to the remaining number of operations. Slack time is the difference between the due date and the expected completion time of a job. A lower ratio means a higher priority, as it indicates that the job has less slack time per operation and is more likely to be late. Slack time per operation is a dynamic priority rule, as it updates the priority index after each operation is completed. Slack time per operation can help minimize the number of tardy jobs and the average tardiness of jobs, as it gives preference to the jobs that are closer to their due dates and have more operations left.

First-come-first-served (FCFS) is not a priority rule that is consistent with the objective of meeting due dates. FCFS is a priority rule that processes jobs in the order of their arrival or release times. FCFS is a simple and fair rule, but it ignores the processing times and due dates of jobs. FCFS can result in poor due date performance, as it can delay urgent or short jobs behind long or non-urgent jobs.

Shortest processing time (SPT) is not a priority rule that is consistent with the objective of meeting due dates. SPT is a priority rule that processes jobs in ascending order of their processing times. SPT is an effective rule for minimizing the average flow time and work-in-process inventory of jobs, as it clears out small jobs quickly and reduces congestion in the system. However, SPT does not consider the due dates of jobs, and it can make long or urgent jobs late.

Fewest operations remaining is not a priority rule that is consistent with the objective of meeting due dates. Fewest operations remaining is a priority rule that processes jobs in ascending order of their remaining number of operations. Fewest operations remaining is a rule that can reduce the variability and complexity of jobs, as it tends to complete jobs faster and reduce their flow times. However, fewest operations remaining does not take into account the slack times or due dates of jobs, and it can make urgent or short jobs late.

A priority control technique is a method of determining the sequence and timing of production orders in a manufacturing system. A priority control technique can be either push or pull, depending on whether the production orders are initiated by the upstream or downstream processes. A cellular production system is a process of manufacturing that organizes the machines and workers into self-contained cells that can produce different products efficiently and flexibly. A cellular production system is usually based on the principles of lean manufacturing and group technology, which aim to eliminate waste and improve quality.

A pull production activity control (PAC) is a priority control technique that is most appropriate for a firm using a cellular production system. A pull PAC is a method of controlling the flow of materials and work-in-progress in a manufacturing system by using signals from the downstream processes to trigger the release of production orders from the upstream processes. A pull PAC helps to reduce inventory, lead time, and overproduction, as well as to synchronize the production with the customer demand. A pull PAC can be implemented using various techniques, such as kanban cards, containers, or electronic signals.

A shortest processing time (SPT) rule is a priority control technique that assigns the highest priority to the production order that has the shortest processing time at each workstation. An SPT rule helps to minimize the average waiting time and flow time of the production orders, as well as to increase the utilization of the machines and workers. However, an SPT rule does not consider the due dates or the customer demand of the production orders, and may result in poor customer service or low delivery performance.

A distribution requirements planning (DRP) is a priority control technique that determines the quantity and timing of finished goods to be delivered to various distribution centers or customers. A DRP is based on the forecasted demand, the inventory status, and the transportation lead time of the finished goods. A DRP helps to optimize the inventory level, reduce stockouts, and improve customer service. However, a DRP is not suitable for a cellular production system, as it does not control the flow of materials and work-in-progress within the manufacturing system.

A push production activity control (PAC) is a priority control technique that initiates the production orders based on the master production schedule or the forecasted demand from the upstream processes. A push PAC releases the production orders in batches or lots, regardless of the capacity or status of the downstream processes. A push PAC may result in high inventory, long lead time, and overproduction, as well as low flexibility and responsiveness to customer demand. A push PAC is not compatible with a cellular production system, as it contradicts the principles of lean manufacturing and group technology. References: CPIM Exam Content Manual Version 7.0, Domain 6: Plan, Manage, and Execute Detailed Schedules, Section 6.1: Detailed Scheduling Concepts, p. 36; Cellular manufacturing; [Production Activity Control].

 A bill of distribution is a document that specifies the planned channels of inventory disbursement from one or more sources to field warehouses. A bill of distribution is similar to a bill of materials, but it applies to the distribution stage rather than the production stage. A bill of distribution helps to optimize the inventory level, reduce transportation costs, and improve customer service. A bill of distribution considers the factors such as demand patterns, lead times, costs, and capacities of the sources and warehouses.

The other options are not documents that specify the planned channels of inventory disbursement from one or more sources to field warehouses. A supply chain community is a network of organizations that collaborate and coordinate their activities to deliver products or services to customers. A supply chain community includes suppliers, manufacturers, distributors, retailers, and customers. A supply chain community helps to improve the visibility, efficiency, and responsiveness of the supply chain. Interplant demand is the demand for a product or component that is generated by another plant within the same organization. Interplant demand is usually transferred through internal orders or shipments. Interplant demand helps to balance the capacity and resources among different plants. Logistics data interchange (LDI) is a system that enables the exchange of information and documents among different parties involved in the logistics process. LDI uses electronic data interchange (EDI) or other technologies to transmit data such as orders, invoices, shipment notices, and tracking information. LDI helps to improve the accuracy, speed, and security of the logistics transactions. References: CPIM Exam Content Manual Version 7.0, Domain 7: Plan and Manage Distribution, Section 7.1: Distribution Planning Concepts, p. 40; Bill of Distribution; Supply Chain Community.

Third-party logistics (3PL) services are services that involve outsourcing some or all of the logistics functions of a firm, such as transportation, warehousing, distribution, or order fulfillment, to an external provider1. By using 3PL services, a firm can reduce its need to own and operate its own logistics assets, such as trucks, trailers, warehouses, or inventory management systems. These assets are classified as fixed assets on the balance sheet, because they are long-term and tangible assets that are used in the normal course of business2. Therefore, increased use of 3PL services is likely to have the effect of decreasing the fixed assets on a firm’s balance sheet.

The other options are not likely effects of increased use of 3PL services on a firm’s balance sheet. Retained earnings are the accumulated net income of a firm that is not distributed to shareholders as dividends3. Retained earnings are not directly affected by the use of 3PL services, unless the firm’s net income changes as a result of cost savings or revenue growth from outsourcing logistics functions. Accounts receivable are the amounts owed to a firm by its customers for goods or services delivered on credit4. Accounts receivable are not directly affected by the use of 3PL services, unless the firm’s sales volume or credit terms change as a result of improved customer service or delivery performance from outsourcing logistics functions. Intangible assets are non-physical assets that have value based on their intellectual or legal rights, such as patents, trademarks, goodwill, or brand names5. Intangible assets are not directly affected by the use of 3PL services, unless the firm’s reputation or market position changes as a result of enhanced quality or innovation from outsourcing logistics functions. References:

A chase operational strategy is one that adjusts production to match the demand pattern. This means that the inventory level is kept low, as the output is synchronized with the demand. This reduces the inventory cost, as there is less need for holding, ordering, and carrying inventory. A chase strategy also minimizes the risk of obsolescence, spoilage, or excess inventory.

A level operational strategy is one that maintains a constant output rate, production rate, or workforce level. This means that the inventory level fluctuates, as the output may not match the demand. This increases the inventory cost, as there is more need for holding, ordering, and carrying inventory. A level strategy also increases the risk of stockouts, overstocking, or waste.

A mixed-model operational strategy is one that produces several products with the same resources. This means that the inventory level varies, as the output depends on the product mix and the demand. This may increase or decrease the inventory cost, depending on the product characteristics, demand variability, and resource utilization. A mixed-model strategy also requires more flexibility and coordination in production planning and scheduling.

A hybrid operational strategy is one that combines elements of chase and level strategies. This means that the inventory level is balanced, as the output is partly adjusted to the demand and partly kept constant. This may increase or decrease theinventory cost, depending on the degree of adjustment and constancy. A hybrid strategy also requires more trade-offs and compromises in production decision making.

 Customer service performance is the degree to which a product or service meets or exceeds customer expectations. The most relevant measure of customer service performance is how the customer perceives the service compared to what they expected. This measure reflects the customer’s satisfaction and loyalty, which are key factors for business success. Other measures, such as service promised versus measured, customer complaints, or positive feedback, are more related to the supplier’s perspective and may not capture the customer’s true perception of service quality. References : CPIM Part 2 Exam Content Manual, Domain 3: Plan and Manage Demand, Section A: Demand Management, Subsection 4: Customer Service Management, Page 11.

The output of the equipment on Day 6 can be calculated by multiplying the demonstrated capacity, the utilization, and the efficiency. The demonstrated capacity is given as $1,200 per day. The utilization is the ratio of the actual time that the equipment is used to the available time that it could be used. Since the utilization is reduced by 25% on Day 6, it means that the equipment is used for 75% of the available time. Therefore, the utilization is 0.75. The efficiency is the ratio of the actual output to the standard output. It is given as 110%, which means that the equipment produces 10% more than the standard output. Therefore, the efficiency is 1.1. The output on Day 6 can be found by multiplying these three factors:

Output = Demonstrated capacity x Utilization x Efficiency Output = $1,200 x 0.75 x 1.1 Output = $990

Therefore, the output on Day 6 is $990. References: CPIM Part 2 Exam Content Manual, Version 7.0, Domain 6: Plan, Manage, and Execute Detailed Schedules, Section A: Detailed Capacity Planning and Scheduling, Subsection 2: Capacity Management Concepts and Calculations, p. 37-38.

Standardized work is a method of organizing work processes to improve efficiency, quality, and safety1. One of the benefits of standardized work is consistent cycle time, which is the time it takes to complete a task or a process. By standardizing the work sequence, the takt time, and the standard inventory, standardized work reduces the variability and unpredictability of the work flow, and ensures that each task or process is performed in a consistent and optimal manner2. Consistent cycle time can lead to other benefits, such as improved customer satisfaction, reduced waste, increased productivity, and enhanced quality3. References:

External sustainability reporting and verification is an opportunity for a company to communicate its performance in terms of environmental, social, and governance (ESG) aspects. ESG performance refers to how a company manages its impacts and risks on the natural environment, the society, and its own governance structure. By reporting and verifying its ESG performance, a company can demonstrate its commitment to sustainability, transparency, and accountability to its stakeholders, such as investors, customers, employees, regulators, and the public. External sustainability reporting and verification can also provide a company with various benefits, such as improved reputation, enhanced stakeholder trust, increased operational efficiency, reduced costs, and better decision making123.

Offering digital downloads only may result in an increased possibility of loss of intellectual property, as this exposes the online retailer to the risk of cyber theft and piracy. Digital downloads are easier to copy, distribute, and modify without authorization than hard copy books, and the online retailer may lose control over its IP rights and revenues. Cyber thieves may hack into the online retailer’s network and steal its IP assets, such as the content, design, and format of the books. Pirates may also offer illegal copies of the books to consumers at lower prices or for free, undermining the online retailer’s market share and profitability. According to Deloitte Insights, IP cyber theft has largely remained in the shadows compared with more familiar cybercrimes such as the theft of credit card, consumer health, and other personally identifiable information1. However, IP cyber theft can have serious consequences for a company’s future, as IP is the heart of the 21st-century company, an essential motor driving innovation, competitiveness, and the growth of businesses and the economy as a whole1. The WIPO Magazine also notes that digital technology has made IP theft easier, as Bad Actors use technology to flood the online market with pirated and counterfeit goods2. The impact of IP theft on the economy can be significant, as it can result in loss of legitimate sales, reduced tax revenues, lower employment opportunities, and diminished incentives for innovation3. Therefore, an online retailer that moves from delivering hard copy books to offering digital downloads only should take appropriate measures to protect its IP from cyber theft and piracy. This may include using encryption, digital rights management, watermarking, authentication, and monitoring technologies, as well as educating consumers about the value and benefits of legal downloads

Providing a realistic basis for setting internal performance targets can be accomplished through benchmarking. Benchmarking is a process of comparing one’s own performance, processes, or practices with those of other organizations that are recognized as leaders or best in class in a specific area. Benchmarking can help identify gaps, strengths, weaknesses, opportunities, and threats in one’s own performance, as well as learn from the experiences and successes of others. Benchmarking can also help set realistic, achievable, and challenging goals and targets for improvement, based on external standards or benchmarks. Benchmarking can be done internally(within the same organization), externally (with other organizations in the same industry or sector), or functionally (with other organizations that perform similar functions or processes).

Beta testing is not a way of providing a realistic basis for setting internal performance targets. Beta testing is a stage of product development where a sample of potential users or customers test a product or service before it is released to the general public. Beta testing can help identify and fix any bugs, errors, or issues in the product or service, as well as collect feedback and suggestions for improvement. Beta testing can also help evaluate the usability, functionality, and quality of the product or service, as well as measure customer satisfaction and loyalty. Beta testing is not related to setting internal performance targets, as it is focused on the product or service, not the organization.

Breakthrough innovation is not a way of providing a realistic basis for setting internal performance targets. Breakthrough innovation is a type of innovation that creates significant value for customers and markets by introducing new products, services, or business models that are radically different from existing ones. Breakthrough innovation can help create competitive advantage, disrupt existing markets, or create new markets. Breakthrough innovation is not related to setting internal performance targets, as it is focused on the outcome, not the process.

Best practices are not a way of providing a realistic basis for setting internal performance targets. Best practices are methods or techniques that have been proven to be effective and efficient in achieving desired results or outcomes. Best practices can be derived from one’s own experience, research, or benchmarking. Best practices can help improve performance, quality, or productivity by adopting proven solutions or standards. Best practices are not related to setting internal performance targets, as they are focused on the implementation, not the measurement.

The horizon for forecasts that are input to the sales and operations planning (S&OP) process should be long enough that required resources can be properly planned. The S&OP process is a cross-functional process that aligns the demand and supply plans of an organization. The S&OP process consists of several steps, such as data gathering, demand planning, supply planning, pre-S&OP meeting, executive S&OP meeting, and S&OP implementation. The output of the S&OP process is the production plan, which is a statement of the resources needed to meet the aggregate demand plan over a medium-term horizon. The production plan can be stated in different units of measure depending on the type of manufacturing environment, such as hours, units, tons, or dollars. The horizon for forecasts that are input to the S&OP process should be long enough that required resources can be properly planned, meaning that the organization can anticipate and allocate the necessary capacity, materials, labor, equipment, and facilities to meet the expected demand. The horizon for forecasts should also match the lead time for acquiring or changing the resources, as well as the planning cycle for updating the production plan.

Finished goods inventory is a type of inventory that consists of the final products that are ready for sale to the customers. Finished goods inventory investment is the value of the finished goods inventory held by the company. Service level is a measure of customer satisfaction that indicates the percentage of customer orders that can be fulfilled from the available inventory. Service level typically will increase when finished goods inventory investment is increased, because more inventory means more ability to meet the customer demand. However, the relationship between service level and finished goods inventory investment is not linear, but rather asymptotic. This means that service level will increase at a decreasing rate as finished goods inventory investment increases. In other words, the marginal benefit of increasing finished goods inventory investment will diminish as the service level approaches 100%. This is because there is a limit to how much inventory can improve the service level, and beyond a certain point, the additional inventory will not have a significant impact on customer satisfaction.

A 5S environment is a type of workplace organization method that uses a list of five Japanese words: seiri (sort), seiton (set in order), seiso (shine), seiketsu (standardize), and shitsuke (sustain). The goal of 5S is to create a clean, uncluttered, safe, and well organized workplace that helps reduce waste and optimize productivity. A 5S environment should be maintained for the following reason:

• To support standard work: Standard work is a set of documented procedures that define the best way to perform a task or process. Standard work helps to ensure quality, efficiency, safety, and consistency. A 5S environment supports standard work by providing a clear and visible layout of the work area, tools, materials, and instructions. A 5S environment also helps to maintain the condition and performance of the equipment and facilities. A 5S environment enables workers to follow standard work easily and effectively.

Return on investment (ROI) is a financial ratio that measures the profitability of an investment relative to its cost. ROI is calculated by dividing the net income (or profit) generated by the investment by the total cost of the investment. ROI is decreased by any activity that reduces the net income or increases the cost of the investment. Increasing cost of sales is an activity that decreases ROI because it reduces the net income generated by the sales revenue. Cost of sales (or cost of goods sold) is the direct cost of producing or purchasing the goods or services sold by an organization. Cost of sales includes materials, labor, and overhead costs. Increasing cost of sales means that the organization spends more money to produce or acquire the same amount of goods or services, which lowers its profit margin and ROI.

Multiple sourcing is an outsourcing approach in which products or services are contracted to various suppliers needed to conduct the business instead of using traditional single sourcing1. One of the potential advantages of multiple sourcing is that it can lower the price of the products or services, as it creates competition among the suppliers and gives the buyer more bargaining power2. Another potential advantage of multiple sourcing is that it can reduce the risk of supply disruptions, as it diversifies the supply chain and makes the buyer less dependent on any single supplier3. If one supplier fails to deliver due to unforeseen circumstances, such as natural disasters, political instability, or quality issues, the buyer can switch to another supplier or use a combination of suppliers to meet the demand4. Therefore, multiple sourcing can provide lower price and reduced risk as potential advantages in the supplier selection process.

 Long lead-time items are items that take a long time to procure, produce, or deliver. Stable demand means that the demand for these items is predictable and does not fluctuate much over time. A supply chain that supports long lead-time items with stable demand would best be designed to position inventory close to the consumer, because this would reduce the delivery time and improve the customer service level. Positioning inventory close to the consumer also reduces the transportation costs and risks associated with long-distance shipments. A supply chain that uses a pull system, which is based on actual customer orders rather than forecasts, may not be suitable for long lead-time items, because it may not be able to meet the customer demand in a timely manner. A supply chain that is linked through an enterprise resources planning (ERP) system, which is a software system that integrates various business functions and processes, may improve the visibility and coordination of the supply chain, but it does not necessarily reduce the lead time or position inventory close to the consumer. A supply chain that is designed to be responsive, which means that it can quickly adapt to changes in demand or other variables, may not be necessary for long lead-time items with stable demand, because these items have low demand uncertainty and variability. References:

 Vendor-managed inventory (VMI) is a type of supply chain collaboration where the supplier takes responsibility for managing the inventory levels and replenishment orders of the buyer. VMI provides a benefit to the buying company in several ways, such as improving service levels, reducing stockouts, increasing visibility, and enhancing trust. One of the specific benefits of VMI is that it reduces administrative expenses for the buying company. Administrative expenses are the costs associated with the general operations and management of the business, such as salaries, rent, utilities, office supplies, and communication. VMI reduces administrative expenses by eliminating or simplifying the tasks related to inventory management, such as forecasting, ordering, invoicing, and payment. VMI also reduces administrative expenses by streamlining the communication and coordination between the buyer and the supplier, and by reducing the errors and disputes that may arise from inventory discrepancies.

The poka-yoke technique of process design is a method for preventing or detecting errors and defects in the manufacturing process. Poka-yoke means “mistake-proofing” in Japanese, and it aims to eliminate human errors by creating systems that either make it impossible for a mistake to occur or make the mistake immediately obvious once it has occurred1. One way to implement poka-yoke is to use part attributes, which are physical features of a part that ensure it can only be assembled or used in the correct way2. For example, a part attribute can define the correct orientation of a part, such as a notch, a hole, a shape, or a color, so that it can only fit into the matching component. This prevents the operator from inserting the part incorrectly or using the wrong part.

The other options do not illustrate the poka-yoke technique of process design. Reducing the number of types of fasteners is an example of standardization, which is a method for simplifying and streamlining the production process by minimizing variation and complexity3. Customized containers that hold mixed sets of parts are an example of kitting, which is a method for organizing and delivering parts or materials to the point of use or consumption in the production process4. An andon is a visual or audible signal that indicates the status of a machine or process, such as normal,abnormal, or emergency5. An andon can be used to alert operators or supervisors of problems or issues, but it does not prevent or detect errors by itself.

The inventory turns ratio is a financial metric that measures how efficiently a company manages its inventory. The inventory turns ratio is calculated by dividing the cost of goods sold (COGS) by the average inventory investment. The cost of goods sold is the direct cost of producing or purchasing the goods sold by the company. The average inventory investment is the average value of the inventory held by the company over a period of time. A higher inventory turns ratio indicates a higher inventory turnover and a lower inventory holding cost.

In this case, the company sold 8,400 units last year, and the unit cost is $207. Therefore, the cost of goods sold is:

COGS = Unit cost x Units sold = 207 x 8,400 = $1,738,800

The average inventory investment was $42,000. Therefore, the inventory turns ratio is:

Inventory turns ratio = COGS / Average inventory investment = 1,738,800 / 42,000 = 41.4

To express the inventory turns ratio as a whole number, we can round it to the nearest integer. Therefore, the inventory turns ratio is 5.

 Failure Mode and Effects Analysis (FMEA) is a systematic, proactive method for identifying and evaluating the potential causes and impacts of failures in a process, product, or service1. It aims to anticipate and prevent failures by assessing the relative effect and risk of different failure modes1.

The use of FMEA would be most appropriate prior to a new product introduction (NPI). During the NPI phase, FMEA can be used to identify potential failure modes in the design of the product and assess their potential effects on the product’s performance and reliability. This allows for proactive measures to be taken to mitigate or eliminate these risks before the product is launched. FMEA is particularly useful in the early stages of design, as it helps in making informed decisions that can improve the quality and safety of the product1.

In contrast, using FMEA after a one-time quality incident investigation (A) or during evaluation of a new market opportunity © may not be as effective, as these situations do not involve the design or development of a product or process. While FMEA can be used during the define phase of a Six Sigma project (B), its most impactful application is during the design phase of a new product, where it can significantly influence the final outcome.

Maintenance, repair, and operating (MRO) supply systems are systems that manage the inventory and procurement of the items that are used to support the production process, but are not part of the final product. MRO items include spare parts, tools, lubricants, cleaning supplies, safetyequipment, and office supplies. The primary consideration in MRO supply systems typically is stockout costs. Stockout costs are the costs associated with the inability to meet the demand for an item due to insufficient inventory. Stockout costs can include lost sales, customer dissatisfaction, production downtime, emergency orders, and reputation damage. Stockout costs can be very high for MRO items, especially if they are critical for the operation and maintenance of the production equipment. Therefore, MRO supply systems should aim to minimize the risk of stockouts by ensuring adequate availability and accessibility of MRO items.

 The capacity requirements plan is used primarily to balance capacity and load at work centers. A work center is a location where one or more resources perform a specific operation or a group of operations. Capacity is the amount of time or output that a work center can offer for production activities. Load is the amount of time or output that a work center is required to produce based on the planned production schedule. Balancing capacity and load means matching the available capacity with the required load, so that there is no excess or shortage of capacity at any work center.

The capacity requirements plan is a report that shows the projected load and capacity of each work center over a planning horizon. It is derived from the master production schedule (MPS), which specifies the quantity and timing of finished goods to be produced, and the bill of materials (BOM), which specifies the components and materials needed for each finished good. The capacity requirements plan also uses the routing file, which specifies the sequence of operations and work centers required for each finished good, and the work center file, which specifies the capacity and availability of each work center. The capacity requirements plan can help to identify any gaps or surpluses in capacity at each work center and to take corrective actions, such as revising the MPS, rescheduling operations, adding or reducing resources, or outsourcing production.

The other options are not the primary uses of the capacity requirements plan. Calculating the level of available capacity is an input to the capacity requirements plan, not an output. The level of available capacity is determined by the work center file, which contains information such as shifts, hours, efficiency, utilization, and maintenance of each work center. Determining the overall product load profile is not a use of the capacity requirements plan, as it does not consider the product mix or demand variability. The overall product load profile is a general estimate of the total production volume or demand over a period of time. Determining the priority of orders is not a use of thecapacity requirements plan, as it does not consider the due dates or urgency of orders. The priority of orders is determined by using priority rules or dispatching methods, such as first-come-first-served (FCFS), shortest processing time (SPT), earliest due date (EDD), or critical ratio (CR).

Difficult to copy is a defensive operational strategy used to sustain the company’s business over time by creating a unique product or service that is hard for competitors to imitate. The proprietary software for web hosting and order management represents this strategy, as it has been recognized as best-in-class and may have some features or functions that are not easily replicated by others. Difficult to substitute is a defensive operational strategy that creates a product or service that has no close substitutes in the market, making it more valuable and desirable for customers. Difficult to relocate is a defensive operational strategy that locates the production or service facilities in a place that has some advantages or benefits that are not available elsewhere, such as low labor costs, favorable tax policies, or access to natural resources. Scarcity is a defensive operational strategy that creates a product or service that has limited supply or availability, making it more exclusive and attractive for customers. References: CPIM Exam Content Manual Version 7.0, Domain 8: Manage Quality, Continuous Improvement, and Technology, Section 8.1: Quality Concepts, p. 44; Defensive Strategy; Competitive Advantage.

The most appropriate production output reporting method for repetitive manufacturing is backflush. Repetitive manufacturing is a production system where the same or similar products are produced in large quantities or in a continuous flow1. Backflush is a method of reporting output and consumption of materials at the end of the production process, rather than at each operation or stage2. Backflush can simplify and streamline the production output reporting process, as it eliminates the need for tracking and recording each individual transaction or movement of materials and components. Backflush can also reduce the paperwork, errors, and costs associated with production output reporting2.

The other options are not as appropriate as backflush for repetitive manufacturing. Operation-by-operation is a method of reporting output and consumption of materials at each operation or stage of the production process3. This method can provide more detailed and accurate information about the production performance and costs, but it can also be more complex and time-consuming, as itrequires tracking and recording each individual transaction or movement of materials and components. Count point is a method of reporting output and consumption of materials at selected points or milestones in the production process4. This method can provide a balance between detail and simplicity, but it can also introduce errors or discrepancies, as it requires estimating or extrapolating the output and consumption of materials between the count points. Job tickets are documents that record the time, materials, and costs associated with a specific job or order5. This method can provide more flexibility and customization, but it can also be more suitable for job shop or batch production systems, where different products are produced in small quantities or on demand.

Customer relationship management (CRM) is a program that uses data and technology to manage the interactions and relationships with customers. CRM helps to understand the needs, preferences, and behaviors of customers, and to provide them with better products, services, and experiences. In a rapidly changing business environment, a primary advantage of an effective CRM program is earlier identification of shifts in customer preferences. This means that CRM can help to detect and anticipate the changes in customer demand, tastes, or expectations, and to respond accordingly. This can help to improve customer satisfaction, loyalty, and retention, as well as to gain a competitive edge in the market. CRM does not necessarily reduce forecast variability, which is the degree of difference between the actual demand and the forecasted demand. CRM does not necessarily reduce customer order changes, which are the modifications or cancellations of orders by customers. CRM does not necessarily reduce customer defections, which are the losses of customers to competitors or other alternatives. References: CPIM Exam Content Manual Version 7.0, Domain 3: Plan and Manage Demand, Section 3.1: Demand Management Concepts, p. 16; Customer relationship management; Customer Relationship Management (CRM) Definition.

The bullwhip effect is a supply chain phenomenon that causes fluctuations in demand to amplify as they move upstream, from the consumer to the retailer, to the distributor and then to the producer1. The bullwhip effect can result in inefficiencies and costs such as excess inventory, lost revenues, superfluous capacity and poor customer service1.

One of the activities that would be effective to mitigate the bullwhip effect is to reduce lead times, which are the time intervals between placing an order and receiving the goods2. Reducing lead times can help to reduce the uncertainty and variability in demand, as well as improve the responsiveness and flexibility of the supply chain2. By reducing lead times, the supply chain partners can order less frequently and in smaller quantities, while still meeting customer demand. This can reduce the need for safety stock, cycle stock and pipeline stock, and thus lower the inventory carrying costs and risks2.

The other options are not effective activities to mitigate the bullwhip effect. Implementing track and trace technology, which is a method for tracking the origin, history, location and status of a product or its parts throughout the supply chain3, may help to improve the visibility and transparency of the supply chain, but it may not reduce the demand fluctuations or inventory imbalances caused by the bullwhip effect. Using a push system, which is a production system where goods are produced based on forecasted demand rather than actual customer orders4, may increase the risk of overproduction or underproduction, as well as create more inventory and waste in the supply chain. Increasing inventory, which is the stock of goods or materials held by a company to meet customer demand5, may increase the inventory carrying costs and risks, as well as tie up cash flow and working capital.

Product price is most effective in influencing demand in the introduction phase of the product life cycle. The product life cycle is a concept that describes the stages that a product goes through fromits development to its decline. The introduction phase is the first stage, when the product is launched into the market and consumers are made aware of its existence and benefits. In this phase, product price can have a significant impact on the demand for the product, depending on the following factors:

• The degree of product innovation: If the product is highly innovative and offers a unique value proposition to customers, it may have a high price elasticity of demand, meaning that customers are willing to pay a high price for it regardless of the availability of substitutes or competitors1. This is often the case for products that create a new market or category, such as the iPhone or the Kindle2. On the other hand, if the product is not very innovative and offers a similar value proposition to existing products, it may have a low price elasticity of demand, meaning that customers are sensitive to price changes and will switch to cheaper alternatives or competitors if the price is too high1. This is often the case for products that enter an existing market or category, such as generic drugs or copycat products3.
• The degree of market competition: If the product faces little or no competition in the market, it may have more pricing power and flexibility, meaning that it can charge a high price and still generate high demand4. This is often the case for products that have a strong brand image, a loyal customer base, or a patent protection5. On the other hand, if the product faces high competition in the market, it may have less pricing power and flexibility, meaning that it has to charge a low price or offer discounts and promotions to attract and retain customers4. This is often the case for products that have a weak brand image, a low customer loyalty, or a short product life cycle.

Therefore, product price can be an effective tool to influence demand in the introduction phase of the product life cycle, depending on how innovative and competitive the product is. A high price can signal quality, exclusivity, and differentiation, while a low price can signal affordability, accessibility, and penetration.

The percentage of defective parts is the proportion of units that do not meet the specification limits. The process capability index (Cpk) is a measure of how well the process can produce within the specification limits. Both the percentage of defective parts and the Cpk depend on the specification range and the process variation1.

If the supplier changes the tolerance range from + 0.3 mm to + 0.5 mm, the specification range becomes wider, which means that more units will fall within the specification limits and fewer units will be defective. Therefore, the percentage of defective parts decreases.

However, if the process variation remains unchanged, the Cpk will decrease, because Cpk is inversely proportional to the specification range2. A wider specification range means a lower Cpk, which indicates a lower process capability. A lower Cpk also implies a higher percentage of defective parts in relation to the process variation3.

Therefore, the correct answer is D. The percentage of defective parts decreases, and the process capability index decreases.

 Safety capacity in lean environments is where take time is greater than cycle time. Take time is the average time between the start of production of one unit and the start of production of the next unit1. Cycle time is the average time it takes to complete one unit of a product or service2. Safety capacity is the amount of capacity that is reserved to deal with unexpected events or fluctuations in demand or supply3.

In lean environments, the goal is to minimize waste and maximize value by producing only what the customer wants, when the customer wants it, and in the exact amount4. This means that the production system should be synchronized with the customer demand, and the take time should match the cycle time. However, in reality, there may be variations or uncertainties in the demand or supply, such as changes in customer preferences, seasonal patterns, quality issues, equipment breakdowns, or supplier delays. These variations or uncertainties can cause disruptions or imbalances in the production system, leading to stockouts, overproduction, waiting, defects, or rework5.

To cope with these variations or uncertainties, lean environments may use safety capacity as a buffer or contingency plan. Safety capacity is where take time is greater than cycle time, meaning that the production system has some extra capacity to produce more than what the customer currently demands. This extra capacity can be used to absorb the variations or uncertainties and maintain a smooth and stable production flow6. However, safety capacity should not be confused with excess capacity, which is where take time is much greater than cycle time, meaning that the production system has a lot of idle or underutilized resources. Excess capacity is a waste that should be eliminated or reduced in lean environments7.

Therefore, safety capacity in lean environments is where take time is greater than cycle time.

Carrying cost is the cost of holding inventory over a period of time. Carrying cost includes the cost of storage, insurance, taxes, obsolescence, spoilage, and opportunity cost of capital. Carrying cost is usually expressed as a percentage of the inventory value per year. An order point is the level of inventory that triggers a replenishment order. An order point is calculated based on the demand rate, the lead time, and the safety stock. An order point is used to maintain a balance between inventory availability and inventory cost. A planner who chooses to increase the order point for a raw material is most likely to increase the carrying cost, as a higher order point means a higher average inventory level, which in turn means a higher carrying cost. Increasing the order point may reduce the risk ofstockouts and improve customer service, but it also increases the inventory investment and its associated costs.

The other options are not likely to increase as a result of increasing the order point. Ordering cost is the cost of placing and receiving an order. Ordering cost includes the cost of processing, transportation, inspection, and setup. Ordering cost is usually expressed as a fixed amount per order. Ordering cost is not affected by the order point, but by the order quantity and the number of orders. Landed cost is the total cost of delivering a product or service to the customer. Landed cost includes the cost of production, transportation, taxes, duties, and fees. Landed cost is usually expressed as a percentage of the product or service value. Landed cost is not affected by the order point, but by the sourcing, pricing, and logistics decisions. Product cost is the total cost of producing a product or service. Product cost includes the cost of materials, labor, and overhead. Product cost is usually expressed as a variable amount per unit. Product cost is not affected by the order point, but by the production methods, techniques, and efficiency. References: CPIM Exam Content Manual Version 7.0, Domain 5: Plan and Manage Inventory, Section 5.1: Inventory Management Concepts, p. 30; Order Point; Carrying Cost.

When deciding what to report externally regarding sustainability performance, a company should disclose its past results and future strategies. This will help the company to demonstrate its progress, achievements, challenges, and commitments in relation to its environmental, social, and governance (ESG) goals. Disclosing past results and future strategies will also enhance the company’s transparency, accountability, and credibility with its stakeholders, such as investors, customers, employees, regulators, and the public.

Disclosing results of poor performance or acceptable performance alone is not sufficient, as it does not provide a complete picture of the company’s sustainability performance. Moreover, disclosing only poor performance may damage the company’s reputation and trust, while disclosing onlyacceptable performance may raise doubts about the company’s honesty and reliability. Disclosing why current regulations are too costly is irrelevant and inappropriate, as it does not reflect the company’s sustainability performance or efforts. It may also imply that the company is not willing or able to comply with the regulations or improve its sustainability practices.

A reduction in purchased lot sizes will reduce inventory levels. Purchased lot sizes are the quantities of inventory that a stage of the supply chain either produces or purchases at a given time1. Inventory levels are the amount of stock available throughout the distribution network2. By reducing the purchased lot sizes, a company can lower the amount of inventory it holds, which can reduce the inventory costs, such as holding costs, shortage costs, and order costs3.

Holding costs are the costs associated with storing and maintaining inventory, such as rent, utilities, insurance, taxes, depreciation, and obsolescence4. Shortage costs are the costs incurred when demand exceeds supply, such as lost sales, customer dissatisfaction, and backorder costs4. Order costs are the costs involved in placing and receiving orders, such as transportation, inspection, setup, and administrative costs4.

Reducing the purchased lot sizes can lower the holding costs by decreasing the average inventory in the supply chain due to either production or purchases in lot sizes that are larger than those demanded by the customer1. This is also known as cycle inventory1. Reducing the purchased lot sizes can also lower the shortage costs by increasing the frequency of orders and decreasing the lead time between orders5. This can help avoid stockouts and meet customer demand more consistently. Reducing the purchased lot sizes can also lower the order costs by optimizing the order quantity based on the trade-off between holding costs and order costs. This is also known as economic order quantity (EOQ).

Therefore, a reduction in purchased lot sizes will reduce inventory levels and inventory costs.

 A queue is the number of hours that a work order sits in front of a work center before it starts. It also includes the move time required to physically move partially completed items from the previous operation to the next work center1. A queue is used to provide a buffer between the time that a component arrives at a machine or work center and when the operation actually starts2. A queue can help to neutralize delays in previous operations and to reduce the waiting time and flow time of the work orders3.

An order that moves into a work center on schedule following completion of a previous operation will move into the queue in priority sequence. This means that the order will be placed in the queue according to its priority level, which is determined by the priority control technique used for the production system. A priority control technique is a method of determining the sequence and timing of production orders in a manufacturing system4. Some examples of priority control techniques are first-come, first-served (FCFS), shortest processing time (SPT), earliest due date (EDD), and critical ratio (CR). Depending on the priority control technique, an order may move to the beginning, end, or middle of the queue.

An order will not necessarily move to the end or the beginning of the queue, as these positions depend on the priority level of the order and the other orders in the queue. An order will not move into the queue when there is capacity available, as this implies that there is no queue at all. Capacity is the amount of time or resources available for production at a work center5. Capacity can be affected by factors such as machine availability, labor skills, setup time, and maintenance. Capacity planning is a function of determining and adjusting the optimal level of resources needed to meet the demand5.

A customer value proposition (CVP) is a statement that summarizes the benefits that a product or service offers to a target customer segment1. A CVP can help a company differentiate itself from its competitors by highlighting its unique value proposition (UVP), which is the main reason why customers should choose its product or service over others2. A CVP can also help a company communicate its value to its customers, increase customer satisfaction and loyalty, and improve its market position3.

One of the strategies that can improve the effectiveness of a CVP and enhance its differentiation in the market is to adopt best practices that improve product design. Product design is the process of creating a new product or service that solves a customer problem or fulfills a customer need4. By improving product design, a company can create products or services that are more desirable, feasible, and viable for its customers5. Some of the best practices that can improve product design are:

• Understanding the customer: conducting research and analysis to identify the customer segments, their jobs, pains, and gains, and their expectations and preferences. This can help create products or services that are tailored to the customer needs and wants, and deliver value that exceeds their expectations.
• Using the Value Proposition Canvas: a tool that helps design, test, create, and manage products and services that customers actually want. The Value Proposition Canvas consists of two parts: the Customer Profile, which describes the customer segment in terms of their jobs, pains, and gains; and the Value Map, which describes how the product or service creates value for the customer by addressing their jobs, relieving their pains, and creating their gains. The Value Proposition Canvas can help align the product or service with the customer needs and wants, and create a fit between them.
• Applying design thinking: a human-centered approach to innovation that integrates the needs of people, the possibilities of technology, and the requirements of business. Design thinking involves five phases: empathize, define, ideate, prototype, and test. Design thinking can help create products or services that are desirable for the customers, feasible for the technology, and viable for the business.
• Incorporating feedback loops: collecting and analyzing data from customers and stakeholders to measure the performance and impact of the product or service. Feedback loops can help validate the assumptions and hypotheses about the customer needs and wants, test the effectiveness of the value proposition, and identify areas for improvement or innovation.

Therefore, by adopting best practices that improve product design, a company can create products or services that deliver superior value to its customers, and differentiate itself from its competitors in the market.

Replenishment lead time is the time between placing an order and receiving the goods1. Reducing replenishment lead time will result in lower inventory levels, as it will allow the company to order less frequently and in smaller quantities, while still meeting customer demand. This will reduce the safety stock, cycle stock, and pipeline stock that the company needs to hold, and thus lower the inventory carrying costs and risks.

The other options will not result in lower inventory levels. Level loading the MPS means producing at a constant rate regardless of demand fluctuations2. This will result in higher inventory levels, as the company will need to build up inventory during periods of low demand and draw down inventory during periods of high demand. Increasing customer service level means improving the ability to meet customer expectations and requirements3. This will also result in higher inventory levels, as the company will need to hold more safety stock to avoid stockouts and ensure high fill rates. Decentralizing inventory locations means distributing inventory across multiple warehouses or facilities4. This will also result in higher inventory levels, as the company will need to maintain more safety stock at each location to account for demand variability and uncertainty.

 A production cell is a group of machines or workstations that are arranged in a layout that facilitates the flow of materials and work-in-progress in a manufacturing system. A production cell is usually designed to produce a family of products or services that have similar characteristics or requirements. A production cell is often based on the principles of lean manufacturing and group technology, which aim to eliminate waste and improve quality. When designing a production cell, the most important consideration is the flow of materials into the cell and sequencing of operations to minimize total cycle time. The flow of materials into the cell refers to the movement and direction of the raw materials, components, or modules that enter the cell for processing. The sequencing of operations refers to the order and arrangement of the machines or workstations that perform the processing steps within the cell. Minimizing total cycle time refers to reducing the time it takes to complete a product or service from start to finish. By considering these factors, a production cell can achieve high efficiency, flexibility, and productivity.

The other options are not the most important considerations when designing a production cell. The unit per hour requirement for the production cell to meet the sales forecast is not the most important consideration, as it is a result of the demand planning and capacity planning functions, which are separate from the production cell design. The unit per hour requirement indicates how many units of a product or service the production cell needs to produce in an hour to meet the expected customer demand. The output rate for the first operation and move time after the last workstation are not the most important considerations, as they are only parts of the total cycle time calculation, which also includes the processing time and waiting time for each operation. The output rate for the first operation is the number of units that the first machine or workstation in the cell can produce in an hour. The move time after the last workstation is the time it takes to transport the finished product or service from the last machine or workstation in the cell to the next stage or destination. The take time requirement for each operator to meet the monthly production goals of the plant is not the most important consideration, as it is a measure of labor productivity, which is affected by factors such as skill, training, motivation, and supervision. The take time requirement for each operator is the amount of time that an operator needs to complete one unit of a product or service. References: CPIM Exam Content Manual Version 7.0, Domain 6: Plan, Manage, and Execute Detailed Schedules, Section 6.2: Detailed Scheduling Methods, p. 38; Cellular manufacturing; Production Cell.

 In a make-to-stock (MTS) environment, improving estimates of customer demand would improve the trade-off between the cost of inventory and the level of customer service. MTS is a production strategy that manufactures products in anticipation of customer demand, based on forecasts. The main challenge of MTS is to balance the inventory costs and the customer service levels. Inventory costs include holding costs, ordering costs, and obsolescence costs. Customer service levels measure the ability to meet customer demand without delay or stockout. A trade-off exists between these two objectives, as higher inventory levels can increase customer service levels but also increase inventory costs, and vice versa.

Improving estimates of customer demand can help reduce the trade-off between inventory costs and customer service levels, as it can lead to more accurate production planning and inventory management. By forecasting demand more accurately, a company can avoid overproduction or underproduction, which can result in excess inventory or stockouts, respectively. By producing the right amount of products at the right time, a company can lower its inventory costs and increase its customer service levels.

Eliminating raw material stockouts would not improve the trade-off between inventory costs and customer service levels in a MTS environment, as it would not affect the finished goods inventory or the customer demand. Raw material stockouts are a supply issue that can disrupt the production process and cause delays or shortages in the finished goods. However, they do not directly impact the inventory costs or the customer service levels of the finished goods, which are determined by the demand forecasts and the production plans.

Decreasing the frozen time zone would not improve the trade-off between inventory costs and customer service levels in a MTS environment, as it would increase the variability and uncertainty in the production process. The frozen time zone is the period of time in which no changes can be made to the production schedule, as it is considered fixed and final. Decreasing the frozen time zone would allow more flexibility and responsiveness to changes in demand or supply, but it would also increase the risk of errors, disruptions, or inefficiencies in the production process. This could resultin higher production costs, lower quality, or longer lead times, which could negatively affect the inventory costs and the customer service levels.

Reducing manufacturing overtime would not improve the trade-off between inventory costs and customer service levels in a MTS environment, as it would reduce the production capacity and output. Manufacturing overtime is a way of increasing the production capacity and output by extending the working hours of the production resources, such as labor or equipment. Reducing manufacturing overtime would lower the production costs, but it would also lower the production output. This could result in insufficient inventory to meet customer demand, which could lower the customer service levels. References := Make-to-Stock (MTS) Definition, Make-to-Stock (MTS) vs Make-to-Order (MTO) | TradeGecko, Value Creation: Assessing the Cost-Service Trade-off

Compared to traditional supplier relationships, a more strategic view of supplier relationships would require maintaining communication based on trust. Trust is a key factor that enables effective collaboration, information sharing, problem solving, and innovation between supply chain partners12. Trust can also reduce transaction costs, conflicts, and opportunism, and increase commitment, loyalty, and performance34. Therefore, maintaining communication based on trust is essential for developing and sustaining strategic supplier relationships that can create value and competitive advantage for both parties.

The other options are not necessarily required for a more strategic view of supplier relationships, because they are either insufficient or irrelevant. Offering the supplier more business may increase the volume or frequency of transactions, but it does not guarantee a more strategic or long-term relationship. Adopting electronic data interchange (EDI) may improve the efficiency or accuracy of information exchange, but it does not ensure a more collaborative or innovative relationship. Implementing concurrent engineering may enhance the product design or development process, but it does not address the other aspects of a strategic relationship, such as quality, delivery, or risk management.
