 Manufacturing lead time is the time required to acquire, manufacture, or ship goods1. It includes the time required for preprocessing, processing, and postprocessing of a finished product2. The formula for manufacturing lead time is:

Manufacturing lead time = Preprocessing time + Processing time + Postprocessing time

Preprocessing time is the time needed for handling the order, making sales order, and preparing supplies2. Processing time is the period when the product is manufactured or collected. Postprocessing time is the time of delivery2.

In this question, we are given the following information:

• The product is Item A, which requires Operations 10, 20, and 30 in a work cell
• The order quantity is 10 units
• The operations require no set up time
• The processing times for each operation are:

To find the shortest manufacturing lead time, we need to assume that the preprocessing and postprocessing times are zero, and that the operations can be performed in parallel. This means that the work cell can process 10 units of Item A simultaneously, without any waiting or transportation time.

Therefore, the shortest manufacturing lead time is equal to the longest processing time among the three operations. Since Operation 10 has the longest processing time of 1 hour per unit, the shortest manufacturing lead time is:

Manufacturing lead time = 1 hour x 10 units = 10 hours

However, this answer is not among the options given. Therefore, we need to consider another possibility: that the work cell can only process one unit of Item A at a time, and that the operations must be performed in sequence. This means that each unit of Item A must complete Operation 10 before moving to Operation 20, and then to Operation 30. In this case, the shortest manufacturing lead time is equal to the sum of the processing times for all three operations multiplied by the order quantity. Therefore, the shortest manufacturing lead time is:

Manufacturing lead time = (1 hour + 0.5 hour + 0.5 hour) x 10 units = 20 hours

However, this answer is also not among the options given. Therefore, we need to consider one more possibility: that the work cell can process one unit of Item A at a time, but that the operations can be performed in parallel with overlapping times. This means that as soon as one unit of Item A finishes Operation 10, it moves to Operation 20, while another unit of Item A starts Operation 10. Similarly, as soon as one unit of Item A finishes Operation 20, it moves to Operation 30, while another unit of Item A starts Operation 20. In this case, the shortest manufacturing lead time is equal to the sum of the processing times for all three operations plus the processing times for each operation multiplied by the order quantity minus one. Therefore, the shortest manufacturing lead time is:

Manufacturing lead time = (1 hour + 0.5 hour + 0.5 hour) + (1 hour + 0.5 hour + 0.5 hour) x (10 units - 1) = 12 hours

This answer is among the options given and it is the shortest possible manufacturing lead time under these assumptions. Therefore, the correct answer is B. 12 hours.

A company’s process technology and equipment should be characterized by product-independent processes and flexible automation if its competitive business strategy is based on offering customized products or features and a rapid response to market shifts. Product-independent processes are processes that can produce a variety of products or features without requiring major changes or adjustments in the production system. Flexible automation is a type of automation that can adapt to different product specifications or volumes by using programmable or reconfigurable machines, robots, or software. Product-independent processes and flexible automation can enable a company to offer customized products or features and a rapid response to market shifts by allowing it to:

• Produce small batches or single units of products or features that meet specific customer needs or preferences.
• Switch quickly and easily between different products or features without losing time or efficiency.
• Incorporate new technologies, materials, or designs into the production system without disrupting the existing operations.
• Respond to changes in demand or supply by adjusting the production capacity or output accordingly.

Continuous flow processes and a high degree of fixed automation are not suitable for a company’s process technology and equipment if its competitive business strategy is based on offering customized products or features and a rapid response to market shifts. Continuous flow processes are processes that produce products or features in a continuous and uninterrupted manner, without any breaks or buffers between the stages. Fixed automation is a type of automation that uses specialized machines or equipment that are designed to perform a specific task or operation. Continuous flow processes and fixed automation can enable a company to achieve high efficiency, productivity, and quality, but they also have some limitations, such as:

• They are suitable for producing large volumes of standardized products or features that have stable and predictable demand.
• They are difficult and costly to modify or change when there is a need to produce different products or features or to incorporate new technologies, materials, or designs.
• They are inflexible and rigid when there are variations or fluctuations in demand or supply, as they cannot adjust the production capacity or output easily.

Product-independent processes with parallel production lines are not appropriate for a company’s process technology and equipment if its competitive business strategy is based on offering customized products or features and a rapid response to market shifts. Product-independent processes with parallel production lines are processes that use multiple identical machines or equipment that can produce the same product or feature simultaneously. Product-independent processes with parallel production lines can enable a company to increase its production capacity and output, but they also have some drawbacks, such as:

• They are suitable for producing high volumes of standardized products or features that have high and constant demand.
• They are inefficient and wasteful when there is a need to produce different products or features or to incorporate new technologies, materials, or designs, as they require duplication of resources and equipment.
• They are redundant and unnecessary when there are variations or fluctuations in demand or supply, as they create excess inventory or idle capacity.

Product-dependent processes and automation based on product volume are not optimal for a company’s process technology and equipment if its competitive business strategy is based on offering customized products or features and a rapid response to market shifts. Product-dependent processes are processes that can produce only one type of product or feature, or that require significant changes or adjustments in the production system to produce different products or features. Automation based on product volume is a type of automation that uses different machines or equipment depending on the volume of production required for each product or feature. Product-dependent processes and automation based on product volume can enable a company to optimize its production costs and quality, but they also have some disadvantages, such as:

• They are suitable for producing low volumes of specialized products or features that have low variability and uncertainty in demand.
• They are complex and time-consuming when there is a need to produce different products or features or to incorporate new technologies, materials, or designs, as they require frequent changes or setups in the production system.
• They are unresponsive and slow when there are variations or fluctuations in demand or supply, as they cannot adapt the production capacity or output quickly.

 A work cell layout is a type of process layout that arranges equipment and workers according to the sequence of operations performed on a product or service. A work cell layout can improve space utilization by reducing the amount of floor space needed for production, eliminating unnecessary material handling and storage, and increasing the flexibility of the layout. A work cell layout can also reduce cycle time, improve quality, and enhance worker motivation. References: CPIM Exam Content Manual Version 7.0, Domain 6: Plan, Manage, and Execute Detailed Schedules, Section 6.2: Implement Detailed Schedules, Subsection 6.2.3: Describe the principles of work center design and layout (page 58).

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.

 Establishment of goals and baselines prior to entering the plan-do-check-act (PDCA) cycle allows improvement teams to determine whether an effective change was made in the process. Goals are the desired outcomes or targets that the improvement teams want to achieve by implementing changes in the process1. Baselines are the current or initial performance levels of the process beforeimplementing any changes2. By establishing goals and baselines, improvement teams can have a clear direction and a reference point for their improvement efforts.

In the PDCA cycle, improvement teams follow four steps: plan, do, check, and act. In the plan step, they define the problem, analyze the root cause, and propose countermeasures. In the do step, they test the countermeasures on a small scale. In the check step, they measure and evaluate the results of the test and compare them with the goals and baselines. In the act step, they standardize and sustain the successful countermeasures or revise and repeat the cycle if needed3.

By comparing the results with the goals and baselines in the check step, improvement teams can determine whether an effective change was made in the process. An effective change is one that improves the performance of the process and meets or exceeds the goals set by the improvement teams4. If the results show that an effective change was made, improvement teams can move to the act step and implement the change on a larger scale. If not, improvement teams can go back to the plan step and identify new or revised countermeasures5.

Therefore, establishment of goals and baselines prior to entering the PDCA cycle allows improvement teams to determine whether an effective change was made in the process.

According to the CPIM Exam Content Manual, a make-or-buy decision is a strategic decision that involves choosing between manufacturing a product or service internally or purchasing it from an external supplier1. A make-or-buy decision is based on a cost-benefit analysis that considers various factors, such as quality, cost, capacity, lead time, technology, and competitive advantage2.

Some of the potential reasons to make instead of buy a product may include:

• Maintain quality: Making a product internally may allow the firm to control and ensure the quality standards of the product, which may affect customer satisfaction and loyalty. Buyinga product from an external supplier may involve quality risks or uncertainties, especially if the supplier is located in a different country or has different quality systems3.
• Reduce cost: Making a product internally may reduce the total cost of ownership of the product, which includes not only the purchase price, but also the costs of transportation, inventory, inspection, warranty, and maintenance. Buying a product from an external supplier may incur higher total costs due to these factors.
• Keep confidential processes within the firm: Making a product internally may protect the firm’s proprietary or confidential processes that give it a competitive edge in the market. Buying a product from an external supplier may expose the firm’s processes to potential imitation or leakage.

Therefore, the correct answer is C. maintain quality, reduce cost, and keep confidential processes within the firm.

Production activity control (PAC) is the function of managing the flow of materials and work-in-progress in a manufacturing system. PAC is responsible for executing the master production schedule and the material requirements plan, as well as for planning, implementing, and monitoring the production activities. PAC aims to ensure that the required resources are available, that the production orders are released and completed on time, and that the quality and quantity standards are met. A result of effective PAC is that the actual input/output matches the planned input/output. This means that the actual amount and timing of materials, labor, and machines used for production are consistent with the planned amount and timing. This indicates that the production process is efficient, reliable, and synchronized with the demand. This also helps to reduce inventory, lead time, and waste.

The other options are not necessarily results of effective PAC. Less scrap and rework on the shop floor may be a result of effective quality control, which is a separate function from PAC. Quality control is concerned with inspecting and testing the products or services to ensure that they meet the specifications and standards. Fewer machine hours are required for production may be a result of effective process improvement, which is a separate function from PAC. Process improvement is concerned with analyzing and enhancing the production methods and techniques to increase productivity and performance. Available capacity is increased may be a result of effective capacity planning, which is a separate function from PAC. Capacity planning is concerned with determining and adjusting the optimal level of resources needed to meet the demand. References: Production Activity Control - Tutorial; Production Control: Process, Types and Best Practices - ProjectManager; Production control - Wikipedia.

ABC classification is an inventory categorization technique that divides items into three classes based on their usage value, which is the product of the number of units sold and the cost per unit. Class A items have the highest usage value and account for a large proportion of the total inventory value, but a small percentage of the number of items. Class B items have a moderate usage value and account for a moderate proportion of the total inventory value and the number of items. Class C items have the lowest usage value and account for a small proportion of the total inventory value, but a large percentage of the number of items1.

An advantage of applying ABC classification to a firm’s replenishment items is that it allows planners to focus on critical products. Replenishment items are items that are regularly ordered or produced to maintain a certain level of inventory. By using ABC classification, planners can prioritize the replenishment of class A items, which have the highest impact on the firm’s profitability and customer satisfaction. Planners can also apply different inventory management techniques and policies for each class of items, such as more frequent reviews, tighter controls, lower safety stocks, and higher service levels for class A items, and less frequent reviews, simpler controls, higher safetystocks, and lower service levels for class C items234. This way, ABC classification can help planners optimize the replenishment process and reduce costs, waste, and stockouts.

The other options are not advantages of applying ABC classification to a firm’s replenishment items, because they are either irrelevant or incorrect. ABC classification does not distinguish independent demand from dependent demand, which are two types of demand that depend on whether the item is sold to customers or used as a component in another item5. ABC classification does not provide better order quantities than the economic order quantity (EOQ), which is a formula that calculates the optimal order quantity that minimizes the total inventory costs6. ABC classification does not allow the firm to utilize time-phased order point (TPOP), which is a method that determines when to place an order based on the projected inventory position and the lead time7.

 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

A move from acceptance sampling to 100% inspection would be caused by the circumstance of downstream operators encountering recurring defects. Acceptance sampling is a quality control technique that uses statistical sampling to determine whether to accept or reject a production lot of material. It is employed when one or several of the following hold: testing is destructive; the cost of 100% inspection is very high; and 100% inspection takes too long1. 100% inspection is a quality control technique that examines every item in a production lot for defects or nonconformities. It is employed when the cost of passing a defective item is very high; testing is nondestructive; and 100% inspection does not take too long2.

Downstream operators are the workers or machines that perform the subsequent operations or processes on the products after they have been inspected or tested. Downstream operators encountering recurring defects means that the products that have passed the acceptance sampling or testing are still found to be defective or nonconforming by the downstream operators. This can indicate that the acceptance sampling or testing is not effective or reliable in detecting or preventing defects or nonconformities. This can also result in negative consequences, such as rework, waste, delays, customer complaints, or safety issues. Therefore, this circumstance would cause a move from acceptance sampling to 100% inspection, as it would require a more thorough and rigorous quality control technique to ensure that no defective or nonconforming products are passed to the downstream operators.

The other options are not circumstances that would cause a move from acceptance sampling to 100% inspection. History shows that the quality level has been stable from lot to lot is not a circumstance that would cause a move from acceptance sampling to 100% inspection, but rather a circumstance that would support the use of acceptance sampling. Quality level is the proportion of conforming items in a production lot. Quality level being stable from lot to lot means that there is little variation or fluctuation in the quality of the products over time. This can indicate that the production process is under control and consistent in meeting the quality standards or specifications. Therefore, this circumstance would support the use of acceptance sampling, as it would reduce the risk of accepting a defective lot or rejecting a conforming lot.

The company uses one of its qualified suppliers is not a circumstance that would cause a move from acceptance sampling to 100% inspection, but rather a circumstance that would support the use of acceptance sampling. A qualified supplier is a supplier that has met certain quality, delivery, and service standards and has been approved by the company to supply goods or services without inspection or testing. A qualified supplier is expected to maintain a high level of performance and reliability, as well as to report any issues or deviations that may affect the delivery process. Therefore, this circumstance would support the use of acceptance sampling, as it would reduce the need for 100% inspection by relying on the supplier’s quality assurance system.

The percent of defects is expected to be greater than 5% is not a circumstance that would cause a move from acceptance sampling to 100% inspection, but rather a circumstance that would require a change in the acceptance sampling plan. The percent of defects is the proportion of defective items in a production lot. The percent of defects being expected to be greater than 5% means that there is a high probability of finding defective items in the production lot. This can indicate that the production process is out of control or inconsistent in meeting the quality standards or specifications. Therefore, this circumstance would require a change in the acceptance sampling plan, such as reducing the acceptable quality limit (AQL), increasing the sample size, or decreasing the acceptance number, to increase the likelihood of rejecting a defective lot.
