Question 1

Periodic inspection and repair designed to keep equipment reliable is called

Accepted Answer

Preventive maintenance involves periodic inspections and repairs to prevent equipment breakdowns and maintain reliability. Kaizen is a broader continuous improvement concept, lean maintenance focuses on eliminating waste and improving efficiency in maintenance processes, group technology is a manufacturing philosophy that groups similar parts for easier production, and quality at the source involves building quality into the production process to prevent defects.

Question 2

Calculating how many of each part were used in production and using these calculations to adjust actual on-hand inventory balances is called

Accepted Answer

This process is known as backflushing, which involves calculating the quantity of materials used in production and adjusting inventory balances accordingly at the end of the production process. Material requirements planning, uniform plant loading, master production schedule, and Kanban pull system are all related to production planning and control, but do not specifically refer to the process of adjusting inventory balances based on production usage.

Question 3

Applying lean concepts to logistics is difficult unless either the manufacturer or the customer owns the logistics activities.

Accepted Answer

Applying lean concepts to logistics can be challenging because logistics activities often involve multiple parties, such as suppliers, carriers, and warehouses, making it difficult to achieve full control and visibility. However, it is still possible to apply lean principles to logistics through collaboration and communication between these parties to optimize the flow of goods and eliminate waste. Therefore, it is not necessary for the manufacturer or customer to own the logistics activities in order to apply lean concepts.

Question 4

Smoothing the production flow to dampen schedule variation is called

Accepted Answer

Uniform plant loading refers to the practice of smoothing the production flow to reduce variations in the schedule, ensuring a consistent and predictable production process.

Question 5

An inventory or production control system that uses a signaling device to regulate flows is a

Accepted Answer

The answer of An inventory or production control system that...

Question 6

The key to lean procurement is speed.

Accepted Answer

Lean procurement focuses on eliminating waste and improving efficiencies in the procurement process, rather than solely on speed.

Question 7

Lean suppliers tend to charge more; although, the extra charge is generally a good investment.

Accepted Answer

The answer of Lean suppliers tend to charge more; although,...

Question 8

Lean production and Six Sigma work best in chaotic situations.

Accepted Answer

Lean production and Six Sigma are management methodologies that aim to improve business processes and eliminate waste and defects. Both methodologies work best in an organized and stable environment, where the processes and problems are well-defined and understood. In chaotic situations, other management approaches such as agile project management or change management may be more appropriate.

Question 9

The term lean-procurement relates to automatic transaction, sourcing, bidding and auctions using Web-based applications, and the use of software that removes human interaction and integrates with the financial reporting of the firm.

Accepted Answer

Lean procurement focuses on eliminating waste and improving efficiency in the procurement process, rather than specifically on automation or software integration. It aims at streamlining processes, reducing costs, and enhancing value in the procurement cycle, not solely on technology use.

Question 10

In the textbook, Toyota's Tai-ichi Ohno identified which of the following types of waste to be eliminated?

Accepted Answer

Tai-ichi Ohno identified Product defects as a type of waste to be eliminated in the Toyota Production System. He believed that any product or process that did not add value to the customer was considered waste and needed to be eliminated.

Question 11

Which of the following are related to lean production?

Accepted Answer

Lean production is primarily focused on waste elimination to improve efficiency and value.

Question 12

A schedule that pulls material into final assembly at a constant rate is a

Accepted Answer

A level schedule pulls material into final assembly at a constant rate to maintain a steady production flow. This helps to reduce waste and stabilize operations by balancing production with demand. A lean schedule and a uniform schedule are not specific scheduling methods, and a master production schedule and a kanban pull system may not necessarily involve a constant rate of material flow.

Question 13

The focus of the Toyota Production System is on elimination of waste and reduction in inventory.

Accepted Answer

The answer of The focus of the Toyota Production System...

Question 14

There is less uncertainty in service demand than with manufacturing.

Accepted Answer

Service demand often exhibits higher variability and uncertainty compared to manufacturing because it is directly influenced by customer behavior and preferences, which can change rapidly and unpredictably. Manufacturing demand can be more stable as it is driven by orders and inventory levels, which can be planned and managed more systematically.

Question 15

A signaling device used to control production is

Accepted Answer

Kanban is a signaling device that is used to control production in a lean manufacturing system. Kanban helps to ensure that production is paced according to customer demand and that inventory levels are kept low. It is a visual tool that signals the need for production to occur and is used to trigger the replenishment of materials or products.

Question 16

Applying lean concepts in manufacturing balances increases in cost with quality improvement.

Accepted Answer

Applying lean concepts in manufacturing decreases cost while improving quality by eliminating waste and streamlining processes.

Question 17

A philosophy in which similar parts are combined into families, and the processes required to make the parts are arranged in a specialized workcell.

Accepted Answer

The philosophy described here is Group Technology, which involves combining similar parts into families and organizing processes into specialized work cells based on the similarities of the parts. This methodology reduces setup times and streamlines production processes.

Question 18

In the textbook, Toyota's Tai-ichi Ohno identified which of the following types of waste to be eliminated?

Accepted Answer

Tai-ichi Ohno identified overproduction as a type of waste to be eliminated in Toyota's production system. The goal was to only produce what was needed, when it was needed, in the required amount. This helped to reduce excess inventory, transportation costs, and other inefficiencies.

Question 19

The philosophy of making workers personally responsible for the quality of their output and where workers are expected to make the part correctly the first time and to stop the process immediately if there is a problem is called

Accepted Answer

This philosophy is known as "Quality at the source". It is a key principle of lean manufacturing and involves empowering workers to take responsibility for the quality of their work and stop the process immediately if there is a problem. The goal is to create a culture of continuous improvement where workers are constantly looking for ways to improve the quality of their output.

Question 20

There is less uncertainty in service task times than with manufacturing.

Accepted Answer

Service task times often involve more variability due to the human element and customer interactions, unlike manufacturing where processes can be more easily standardized and controlled.
