Free Operations and Supply Chain Management (C720) Questions
A manager would like to use live monitoring of the guitar string production process at a factory. The thickness of each string should be measured and compared to lower and upper limits to determine if the process is consistent or trending toward instability. Which quality control tool should be used?
-
Control chart
-
Histogram
-
Check sheet
-
Flow chart
Explanation
A control chart is used to monitor process performance over time by plotting measurements against predefined upper and lower control limits. It helps detect trends, shifts, or variations in the process, indicating whether the production remains stable or if corrective actions are needed. By comparing each guitar string’s thickness to these limits, the manager can identify inconsistencies or deviations before they become significant issues.
Correct answer:
Control chart
Which of the following metrics is primarily used to assess the reliability of a supply chain in delivering products to customers as promised
-
Lead time
-
Defect level
-
On-time delivery
-
Inventory turnover
Explanation
Correct Answer C: On-time delivery
Explanation:
On-time delivery is the key metric used to evaluate the reliability of a supply chain in ensuring that products reach customers on the promised date. It reflects how dependable the supply chain is in meeting delivery commitments.
Why other options are wrong:
A) Lead time: While lead time measures the time from order to delivery, it doesn't directly assess reliability in terms of meeting the promised delivery date.
B) Defect level: This measures the quality of products, not the reliability of on-time delivery.
D) Inventory turnover: This measures how quickly inventory is sold and replaced, not the reliability of delivery.
Which change represents a source of opportunities for the purpose of SWOT analysis?
-
Change in core competencies
-
Change in inventory method
-
Change in facility layout
-
Change in consumer lifestyles
Explanation
In SWOT analysis, opportunities arise from external factors that the company can leverage for growth or advantage. A change in consumer lifestyles is an external trend that can create new market demand or product opportunities. Changes in core competencies, inventory methods, or facility layout are internal factors, which relate more to strengths or weaknesses rather than opportunities.
Correct answer:
Change in consumer lifestyles
A manufacturing company produces several final products at one facility. The production manager wants to implement lean principles to improve production efficiency. Which strategy should the manager use for this facility?
-
Keep a higher inventory of each product in order to satisfy demand
-
Make a large number of one product before switching to another
-
Have each production machine operate at its maximum capacity
-
Match the total production of each item to average demand
Explanation
Lean principles emphasize producing only what is needed when it is needed to reduce waste and improve efficiency. By matching total production of each item to average demand, the company avoids overproduction, minimizes inventory costs, and aligns output with customer needs. Producing in large batches or maintaining high inventory contradicts lean goals, while running machines at maximum capacity may not account for demand variability.
Correct answer:
Match the total production of each item to average demand
_____ is the planning, scheduling, and control of the activities that transform inputs into finished goods and service
-
Operations management
-
Supply chain management
-
The operations function
-
A supply chain
Explanation
Correct Answer A: Operations management
Explanation
Operations management is responsible for overseeing the processes involved in transforming inputs (such as raw materials and labor) into finished products or services. It includes planning, scheduling, and controlling activities to ensure efficient production.
Why other options are wrong
B) Supply chain management:
Supply chain management focuses on the movement of goods and services across the entire supply chain, from raw material sourcing to final customer delivery. While it plays a key role in overall production, it does not specifically focus on the transformation process of inputs to finished goods.
C) The operations function:
The operations function is a part of an organization that handles operations management, but operations management itself is a broader discipline that includes activities beyond just overseeing the function, such as scheduling, planning, and controlling the transformation process.
D) A supply chain:
A supply chain refers to the entire network involved in the creation and distribution of products or services, including suppliers, manufacturers, and distributors. It does not specifically focus on the transformation of inputs into final goods and services, which is the primary responsibility of operations management.
In order to improve profitability, a company wants to achieve economies of scale. What is one strategy for the company to better attain economies of scale?
-
Emphasize a project-oriented operation
-
Implement a process layout for the facility
-
Use general machinery for greater flexibility
-
Utilize the same equipment for all products
Explanation
Economies of scale occur when increasing production lowers the average cost per unit, often through standardization and efficient use of resources. By utilizing the same equipment for all products, the company can spread fixed costs over a larger output and reduce setup and operational complexity, which improves efficiency and lowers unit costs. This approach contrasts with using general machinery or a project-oriented operation, which are more flexible but less efficient for mass production.
Correct answer:
Utilize the same equipment for all products
A business executive is working with a team of leaders to determine how to best achieve economies of scale for the products produced by the business. Which type of processes should be used in working toward this goal?
-
Departmental
-
Continuous flow
-
Project
-
Job shop
Explanation
To achieve economies of scale, a business benefits from continuous flow processes, which are designed for high-volume, standardized production. Continuous flow minimizes production costs per unit by maximizing efficiency, reducing setup times, and fully utilizing equipment. In contrast, project or job shop processes focus on low-volume, customized production, which does not generate the same cost advantages from scale.
Correct answer:
Continuous flow
A set of three or more companies directly linked by one or more of the upstream and downstream flows of products, services, finances, and information from a source to a customer is referred to as
-
Logistics
-
Distribution management
-
A supply chain
-
A distribution center
-
A value chain
Explanation
Correct Answer C: A supply chain
Explanation:
A supply chain is a network of multiple companies involved in the movement of goods, services, finances, and information from suppliers to customers. It includes suppliers, manufacturers, distributors, and retailers, all working together to deliver a final product or service.
Why other options are wrong:
A) Logistics:
Logistics focuses on the transportation, warehousing, and distribution of goods, but it does not encompass the entire network of companies involved in a supply chain.
B) Distribution management:
This refers specifically to the movement and delivery of goods but does not cover the broader interactions among multiple companies within a supply chain.
D) A distribution center:
A distribution center is a physical facility used for storing and distributing goods, not the entire network of suppliers and customers.
E) A value chain:
A value chain includes all activities that add value to a product, but it is a broader concept that extends beyond just the upstream and downstream flow of goods, services, and information.
The theoretical ideal supply chain process collaboration is
-
internal process integration
-
forward and backward integration from the supplier's supplier to the customer's customer
-
backward process integration with valued first-tier suppliers
-
forward process integration with valued first-tier customers
Explanation
Correct Answer B: forward and backward integration from the supplier's supplier to the customer's customer
Explanation:
The ideal collaboration in supply chain management encompasses full integration across the entire supply chain, extending from the supplier's supplier to the customer's customer. This creates a seamless flow of information, goods, and services, resulting in enhanced efficiency, responsiveness, and alignment with customer needs.
Why other options are wrong:
A) internal process integration: While internal process integration is important, it only covers internal company operations and doesn't involve the wider supply chain collaboration.
C) backward process integration with valued first-tier suppliers: This is a partial integration strategy, but it doesn't address the entire supply chain, limiting the collaboration to suppliers only.
D) forward process integration with valued first-tier customers: This also represents only a partial integration, focusing on customer relationships but ignoring the full scope of the supply chain from suppliers.
What is the primary advantage of outsourcing non-core services in operations and supply chain management
-
Increased control over all business functions
-
Enhanced focus on core competencies
-
Higher operational costs
-
Decreased reliance on external suppliers
Explanation
Correct Answer B: Enhanced focus on core competencies
Explanation:
Outsourcing non-core services allows a company to concentrate on its primary strengths while delegating secondary functions to specialized providers. This improves efficiency, innovation, and competitive advantage.
Why other options are wrong:
A) Increased control over all business functions: Outsourcing actually reduces direct control over outsourced tasks, as they are managed by third-party providers.
C) Higher operational costs: Outsourcing typically reduces costs by leveraging the expertise and economies of scale of external providers.
D) Decreased reliance on external suppliers: Outsourcing increases reliance on external suppliers rather than decreasing it.
