A purchase order is issued to the supplier for each delivery requirement is an activity that represents waste in a system. Waste is any activity or process that does not add value to the customer or the product, but consumes resources, time, or money. Waste can reduce the efficiency, productivity, and quality of the system, as well as increase the costs, defects, or delays.Waste can be classified into seven types: overproduction, inventory, transportation, motion, waiting, overprocessing, and defects1.

Issuing a purchase order to the supplier for each delivery requirement is an example of overprocessing waste. Overprocessing waste is any activity or process that is unnecessary or excessive for meeting the customer needs or specifications. Overprocessing waste can result from poor communication, unclear requirements, redundant tasks, or outdated procedures. Issuing a purchase order to the supplier for each delivery requirement is an overprocessing waste because it involves more paperwork, approvals, and transactions than needed. It can also create confusion, errors, or delays in the delivery process.A better way to eliminate this waste is to use a pull system, such as kanban2, that signals the supplier to deliver only when there is a demand from the customer.

The other options are not activities that represent waste in a system. More kanbans with smaller quantities are added to the supply chain is an activity that reduces waste in a system. Kanban is a pull system that uses visual signals, such as cards or containers, to indicate when and how much to produce or deliver.Kanban can help reduce waste by synchronizing the production and delivery processes with the customer demand, minimizing inventory levels, improving quality and efficiency, and preventing overproduction or underproduction3. Adding more kanbans with smaller quantities can help reduce inventory waste by lowering the holding costs, transportation costs, or obsolescence costs of inventory. It can also help reduce overproduction waste by producing or delivering only what is needed by the customer.

A kanban is eliminated from the system is an activity that reduces waste in a system. Eliminating a kanban from the system means reducing the number of signals or containers used in the production or delivery process.Eliminating a kanban from the system can help reduce waste by increasing the throughput and velocity of the process, reducing cycle times and lead times, improving responsiveness and flexibility, and enhancing customer satisfaction4.

A production forecast is issued to the supplier is not an activity that represents waste in a system. A production forecast is an estimate of the future demand or sales of a product or service. A production forecast can help plan and manage the production and delivery processes by determining how much and when to produce or deliver.A production forecast can help reduce waste by optimizing the use of resources and capacity, minimizing inventory levels and costs, improving service levels and quality, and avoiding stockouts or shortages5. Issuing a production forecast to the supplier can help align the production and delivery processes with the customer demand and expectations.

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.

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.Reference: 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).

The sales and operations planning (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. Once the S&OP process has been completed, the executive S&OP meeting approves the final production plan, which is the output of the supply planning step. The production plan is a statement of the resources needed to meet the aggregate demand plan over a medium-term horizon. The functional responsibility of operations is to meet the revised production plan by developing and executing the master production schedule (MPS) and the detailed schedules. The MPS is a statement of the specific end items to be produced in each time period of the short-term horizon. The detailed schedules are the statements of the specific materials, resources, and activities needed to execute the MPS.Reference: CPIM Exam Content Manual Version 7.0, Domain 4: Plan and Manage Supply, Section 4.1: Develop Supply Plans, Subsection 4.1.2: Describe how to develop a production plan (page 36).

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.Reference: 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).

A lean relationship is a type of supplier-customer relationship that focuses on eliminating waste, improving quality, and reducing costs throughout the supply chain. A lean relationship requires a high level of collaboration, trust, and transparency between the supplier and the customer. Communication between the counterparts at the two companies is an essential activity that will enhance a successful lean relationship. Communication can help to align the goals, expectations, and performance measures of the supplier and the customer, as well as to identify and resolve any issues or problems that may arise. Communication can also facilitate information sharing, feedback, and continuous improvement initiatives.Reference: CPIM Exam Content Manual Version 7.0, Domain 7: Plan and Manage Distribution, Section 7.1: Develop Distribution Plans, Subsection 7.1.3: Describe how to develop supplier-customer relationships (page 66).

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.

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 the demand 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.

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.
