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.

A two-bin system is a type of inventory management technique that uses two containers or bins to store and replenish items. When the first bin is empty, the second bin is used to supply the demand while the first bin is reordered. A two-bin system is most responsive to changes in demand levels because it triggers replenishment orders based on actual consumption rather than fixed time intervals or reorder points. A two-bin system can reduce stockouts, improve service levels, and lower inventory costs. References: CPIM Exam Content Manual Version 7.0, Domain 5: Plan and Manage Inventory, Section 5.2: Implement Inventory Plans, Subsection 5.2.3: Describe how to implement inventory replenishment techniques (page 46).

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.

Implosion in distribution requirements planning (DRP) is the process of calculating the gross requirements for a supplying location based on the net requirements of its customers or demand sources1. Implosion is the opposite of explosion, which is the process of calculating the net requirements for a demand source based on the gross requirements of its customers or demand sources2. Implosion and explosion are used to synchronize the supply and demand across different levels of the distribution network3.

An example of implosion in DRP is gathering information from several field locations and aggregating it at the manufacturing facility. This example shows how the manufacturing facility, which is the supplying location, can determine its gross requirements by adding up the net requirements of its field locations, which are its customers or demand sources. This way, the manufacturing facility can plan its production and inventory levels to meet the demand from the field locations.

Operations strategy is the process of aligning the operations function with the strategic goals of the organization. It involves translating market requirements into operations decisions that support the competitive priorities of the organization. Operations strategy is not a bottom-up reflection of what the whole group or business wants to do, but rather a top-down alignment of the operations function with the overall business strategy. Operations strategy is not a top-down activity where operations improvements cumulatively build strategy, but rather a deliberate and coherent plan that guides the design and management of the operations system. Operations strategy is not only about exploiting operations capabilities in the global market, but also about developing and sustaining those capabilities in response to the changing market needs.

Safety stock is a type of inventory that is held in excess of the expected demand to protect against uncertainties such as demand variability, lead time variability, or supply disruptions. Safety stock can help to reduce the risk of stockouts, which are situations where the inventory level falls below thedemand level and the customer orders cannot be fulfilled. Safety stock can be determined by using different methods, such as statistical models, service level policies, or empirical rules. One of the common criteria that is used to determine safety stock in a distribution center (DC) is the probability of stocking out, which is the likelihood that the inventory level will be insufficient to meet the demand during a replenishment cycle. The probability of stocking out can be calculated by using the normal distribution, assuming that the demand and lead time are normally distributed. The probability of stocking out can also be expressed as the complementary value of the service level, which is the percentage of customer orders that can be satisfied from the available inventory. A higher probability of stocking out implies a lower service level and a lower safety stock. A lower probability of stocking out implies a higher service level and a higher safety stock.

 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).

Full pegging is a method of tracing the relationship between supply and demand in a manufacturing system. Full pegging shows the link between each demand and its corresponding supply, as well as the link between each demand and the highest-level order that triggered it. Full pegging helps to identify the impact of changes in demand or supply on the production plan, and to make adjustments accordingly. Full pegging is most beneficial in an assemble-to-order (ATO) environment, where products are customized by assembling standardized components or modules according to customer specifications. In an ATO environment, full pegging can show the connection between the finished products, the components or modules, and the customer orders. This can help to optimize the inventory level, reduce lead time, and improve customer service.

Full pegging is not very useful in the other production environments. Distribute-to-order is a production strategy that delivers finished products from inventory to customers based on their orders. There is no customization or assembly involved in this strategy, so full pegging is not needed. Make-to-order is a production strategy that produces customized products from raw materials or components after receiving customer orders. There is no standardization ormodularization involved in this strategy, so full pegging is not applicable. Make-to-stock is a production strategy that produces standardized products in advance of customer demand, and stores them in inventory until they are sold. There is no customization or assembly involved in this strategy, so full pegging is not relevant. References: CPIM Exam Content Manual Version 7.0, Domain 4: Plan and Manage Supply, Section 4.1: Supply Planning Concepts, p. 23; Full Pegging; Assemble to order.

Landed cost represents the total cost of a product on its journey from the factory floor to the buyer’s door. It includes the price of goods, shipment costs, insurance fees, customs duties, and any other charges incurred along the way1. Therefore, purchasing and delivering a purchased product to its final destination is the best representation of landed cost among the given options.

Combining smaller shipments to take advantage of bulk efficiencies is not a representation of landed cost, but rather a strategy to reduce it. Bulk efficiencies are the benefits or savings that result from purchasing or shipping large quantities of goods at once, such as lower unit prices, transportation costs, or handling fees. Combining smaller shipments to take advantage of bulk efficiencies can help lower the landed cost by reducing some of the charges involved in the delivery process2.

Supplier absorbing freight charges is not a representation of landed cost, but rather a condition or term of sale. Freight charges are the fees paid to transport goods from one place to another by land, sea, or air. Supplier absorbing freight charges means that the supplier pays for the freight charges and does not pass them on to the buyer. This can affect the landed cost depending on whether the sale is based on free on board (FOB) or cost, insurance, and freight (CIF) terms. FOB means that the buyer is responsible for the freight charges and other costs after the goods are loaded on board the carrier at the point of origin. CIF means that the supplier is responsible for the freight charges and other costs until the goods reach the point of destination3.

Duties levied on imports and exports are not a representation of landed cost, but rather a component or factor of it. Duties are taxes or fees imposed by a government on goods that are imported or exported across its borders. Duties can affect the landed cost by increasing the price of goods or adding extra charges to the delivery process. Duties can vary depending on the type, value, origin, or destination of the goods4.

Collaborative planning, forecasting, and replenishment (CPFR) is a set of actions taken by supply chain partners to plan and communicate tasks to meet customer demand while reducing cost. It includes business planning, sales forecasting, and replenishment of raw materials and finished goods1. CPFR typically would be most effective for a regional headquarters for a large home improvement retailer, because this type of organization can benefit from the following advantages of CPFR:

• CPFR can strengthen the supply chain partner relationships between the regional headquarters and its suppliers, distributors, and stores, by enhancing trust, transparency, and coordination2.
• CPFR can provide analysis of sales and order forecast which improves the forecast accuracy, by using customer inputs and data from partners in the value chain, as well as advanced analytical tools and techniques3.
• CPFR can manage the demand chain and proactively eliminate problems before they appear, by identifying and resolving potential issues or conflicts in the planning, forecasting, and replenishment processes4.
• CPFR can allow collaboration on future requirements and plans, by involving all the relevant stakeholders in the decision-making process and aligning their goals and expectations5.
• CPFR can combine planning, forecasting and logistic activities, by integrating the best practices in sales and marketing (e.g. such as category management) to supply chain planning and execution processes2.

The other options are not as suitable for CPFR as a regional headquarters for a large home improvement retailer. A distributor with a few major customers and many smaller customers may not have enough incentives or resources to implement CPFR with all its customers, especially the smaller ones who may have low volumes or high variability in demand. A manufacturer that sells directly to a large number of firms may face challenges in coordinating and communicating with all its customers, as well as managing the complexity and diversity of their demand patterns. A company that has a large number of geographically dispersed suppliers may encounter difficulties in establishing trust and transparency with its suppliers, as well as ensuring the quality and reliability of their products or services.
