Which of the following activities represents waste in a system?
Answer : D
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 Overprocessing waste can result from poor communication, unclear requirements, redundant tasks, or outdated procedures.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.
When a certified supplier's delivery performance declines, a company should respond initially by:
Answer : C
When a certified supplier's delivery performance declines, a company should respond initially by communicating with the supplier to investigate the source of the problem. A certified 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 certified 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. However, sometimes a certified supplier may experience a decline in delivery performance, which can cause delays, disruptions, or dissatisfaction for the company and its customers.
The best way to deal with a decline in delivery performance from a certified supplier is to communicate with the supplier and find out the root cause of the problem. Communication is essential for maintaining a good relationship with the supplier and for resolving any issues or conflicts that may arise. Communication can help the company and the supplier to understand each other's expectations, needs, and challenges, as well as to identify and implement corrective actions or preventive measures. Communication can also help to restore trust and confidence between the parties and to prevent further deterioration of performance.
Tightening performance criteria for the supplier is not an appropriate initial response when a certified supplier's delivery performance declines. Tightening performance criteria means imposing stricter standards or requirements on the supplier, such as reducing lead times, increasing penalties, or demanding more frequent reports. Tightening performance criteria may seem like a way of holding the supplier accountable and motivating them to improve their performance, but it can also have negative consequences. Tightening performance criteria can create more pressure and stress for the supplier, which can affect their quality, productivity, or morale. It can also damage the relationship with the supplier, as it may signal a lack of trust, respect, or cooperation from the company.
Establishing a temporary buffer of finished goods inventory at the supplier is not an effective initial response when a certified supplier's delivery performance declines. Establishing a temporary buffer of finished goods inventory means storing extra units of products at the supplier's location to compensate for any delays or shortages in delivery. Establishing a temporary buffer of finished goods inventory may seem like a way of ensuring availability and continuity of supply, but it can also have drawbacks. Establishing a temporary buffer of finished goods inventory can increase inventory costs, such as holding costs, transportation costs, or obsolescence costs. It can also reduce inventory visibility and control, as it may be difficult to track or manage the inventory at the supplier's location. Moreover, establishing a temporary buffer of finished goods inventory does not address the root cause of the decline in delivery performance, but rather masks or postpones it.
Increasing the standard lead time of the component to allow for supplier delays is not a suitable initial response when a certified supplier's delivery performance declines. Increasing the standard lead time of the component means extending the time between placing an order and receiving it from the supplier. Increasing the standard lead time of the component may seem like a way of adjusting to the decline in delivery performance and avoiding late deliveries, but it can also have disadvantages. Increasing the standard lead time of the component can reduce customer satisfaction and loyalty, as it may result in longer waiting times or missed deadlines for the customers. It can also reduce operational efficiency and flexibility, as it may limit the ability to respond to changes in demand or supply. Furthermore, increasing the standard lead time of the component does not solve the problem of the decline in delivery performance, but rather accepts or tolerates it.
In which of the following situations would the use of a failure mode effect analysis (FMEA) be most appropriate?
Answer : D
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.
Which of the following strategies can improve the effectiveness of a company's customer value proposition and enhance its differentiation in the market?
Answer : D
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.
A focused differentiation strategy is best chosen with:
Answer : D
A focused differentiation strategy is a type of focus strategy that targets a narrow buyer segment and pursues a unique competitive advantage.A focus strategy is a business-level strategy that involves concentrating on a specific market niche or segment and tailoring the products or services to the needs and preferences of that niche1.A differentiation strategy is a business-level strategy that involves creating a product or service that is perceived as unique, distinctive, or superior by the customers, and charging a premium price for it2. A focused differentiation strategy combines these two approaches by offering a differentiated product or service to a narrow market segment that has unique demands or characteristics.This strategy allows the firm to create value for its customers and charge higher prices than its competitors, while avoiding direct competition with firms that target a broader market or offer lower-cost products or services3.
An example of a focused differentiation strategy is Lululemon, a Canadian company that sells high-end yoga and athletic apparel. Lululemon targets a niche market of health-conscious, affluent, and fashion-oriented women who are willing to pay premium prices for its products. Lululemon differentiates itself from other sportswear brands by offering high-quality, stylish, and innovative products that are designed to enhance the performance and comfort of its customers.Lululemon also fosters a strong brand identity and community among its customers by providing yoga classes, fitness events, online platforms, and social media engagement4.

What is the shortest manufacturing lead time required for 10 units of Item A assuming that it must complete Operations 10, 20, and 30 in a work cell, and these operations require no set up time''?
Answer : B
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.
Which of the following techniques would be most appropriate to use to develop a forecast?
Answer : C
Exponential smoothing is a forecasting technique that uses a weighted average of past and present data to predict future values. It is suitable for time series data that have a stable or slowly changing trend and no significant seasonal variations. Exponential smoothing assigns more weight to the most recent data, giving it a higher influence on the forecast. This makes it more responsive to changes in demand patterns than other techniques, such as moving average or time series decomposition, which use fixed weights or historical data. The Delphi method is a qualitative technique that involves a panel of experts who provide their opinions and feedback on a topic through multiple rounds of surveys. It is not based on historical data or mathematical formulas, but rather on human judgment and consensus. Therefore, it is not appropriate for developing a forecast.Reference: CPIM Part 2 Exam Content Manual, Version 7.0, Domain 3: Plan and Manage Demand, Section A: Demand Management, Subsection 2: Forecasting Techniques and Methods, p. 14-15.
