Question 1

Just-in-Time (JIT) manufacturing is also called make-to-stock manufacturing.

Accepted Answer

JIT manufacturing is the opposite of make-to-stock manufacturing. It focuses on producing goods in response to demand rather than building up inventory in anticipation of demand.

Question 2

A setup is the time required to prepare an operation for a new production run.

Accepted Answer

A setup is the time required to prepare for a new production run, such as cleaning machines, changing tools or materials, adjusting settings, etc.

Question 3

In the just-in-time (JIT) philosophy, unexpected downtime is the result of unreliable processes.

Accepted Answer

JIT relies on the efficiency and reliability of processes to ensure that materials and products are available exactly when needed. Unexpected downtime suggests that a process has failed, which disrupts the flow of materials and can lead to delays and inefficiencies. Therefore, JIT philosophy considers unexpected downtime as a result of unreliable processes.

Question 4

Just-in-Time (JIT) manufacturing favors organizing work around products rather than around processes.

Accepted Answer

Just-in-Time (JIT) manufacturing focuses on producing products based on customer demand, and therefore, favors organizing work around products rather than processes. This helps to minimize waste and improve efficiency in the production process.

Question 5

Lead time reduction can be a cost-saving goal for any processed item.

Accepted Answer

By reducing the lead time for producing an item, companies can decrease the time and resources required for production, which can translate into cost savings. Additionally, reducing lead time can improve customer satisfaction by providing faster delivery of goods.

Question 6

All lead time are considered as value-added lead time.

Accepted Answer

Not all lead times are value-added, some of them are non-value-added and can be considered as waste.

Question 7

The just-in-time (JIT) philosophy views inventory as a necessary buffer to protect against process problems.

Accepted Answer

The JIT philosophy views inventory as waste and strives to minimize it by using a pull-based system where items are produced only when needed in the process. The focus is on streamlining processes to reduce lead time and eliminate the need for inventory buffers.

Question 8

Employee involvement in a product-oriented factory emphasizes employee teams, rather than individual employees.

Accepted Answer

In a product-oriented factory, where the focus is on producing goods efficiently and effectively, employee involvement is often achieved through the use of employee teams. Teamwork and collaboration are encouraged in order to increase productivity and quality, whereas individual efforts may be less emphasized.

Question 9

The just-in-time (JIT) philosophy views inventory as an unnecessary waste of resources.

Accepted Answer

JIT philosophy aims to reduce waste and increase efficiency by producing goods only when they are needed, rather than keeping large inventories on hand. Therefore, inventory is seen as an unnecessary waste of resources.

Question 10

Just-in-Time (JIT) manufacturing favors organizing work around processes rather than around products.

Accepted Answer

The answer of Just-in-Time (JIT) manufacturing favors organizing work around...

Question 11

A make-to-order company matches its production schedules to actual customer orders.

Accepted Answer

In make-to-order production, the company only starts production once a customer order is received, therefore matching production schedules to actual customer orders.

Question 12

Long setups and large batch sizes result in smaller inventories.

Accepted Answer

Long setups and large batch sizes typically lead to larger inventories because more items are produced before switching to the next product, leading to excess stock.

Question 13

Just-in-Time (JIT) manufacturing focuses on reducing time, cost, and poor quality in processes.

Accepted Answer

JIT manufacturing is a lean manufacturing strategy that aims to optimize production processes by reducing waste, increasing efficiency, and improving overall quality. This is achieved through a number of techniques such as reducing inventory levels, maintaining a steady flow of materials, and using visual management tools to identify and address problems quickly. The ultimate goal of JIT is to improve customer satisfaction by providing high-quality products at the lowest possible cost and in the shortest possible time.

Question 14

Just-in-Time (JIT) manufacturing is also called make-to-order manufacturing.

Accepted Answer

JIT manufacturing is a type of manufacturing where products are produced only when they are needed, in response to customer orders or demand. This is also referred to as make-to-order manufacturing.

Question 15

Large batch sizes increase lead time.

Accepted Answer

Large batch sizes require more time for production and processing, which increases the overall lead time. This can lead to delays in delivering finished goods to customers.

Question 16

Lead time is the process time between start and completion.

Accepted Answer

Lead time is defined as the time it takes for a process to be completed, starting from the time the order is placed until it is delivered to the customer. It includes all aspects of the process, such as design, production, packaging, and shipping. Therefore, it is the process time between the start and completion of an order.

Question 17

Reducing wait time is directly linked to reducing inventory.

Accepted Answer

When wait time is reduced, customers receive their goods or services more quickly, which means there is less need for inventory to build up as back stock. This in turn reduces inventory costs and frees up space for other uses.

Question 18

Lead time includes both value-added time and non-value-added time.

Accepted Answer

Lead time is the total time taken for a process or product to be completed. It includes value-added time (time spent on activities that add value to the final product) and non-value-added time (time spent on activities that do not add value to the final product, such as waiting or processing delays). Therefore, the statement is true.

Question 19

Within-batch wait time increases total lead time.

Accepted Answer

Within-batch wait time refers to the time a job spends waiting within a batch or group of jobs before it is processed. This wait time adds to the total lead time of the job and slows down the overall process. This is because the job cannot move to the next stage of processing until the entire batch is complete. Therefore, minimizing within-batch wait time can help reduce overall lead time.

Question 20

Reducing wait time is not linked to reducing inventory.

Accepted Answer

Reducing wait time can actually lead to a reduction in inventory by improving efficiency and streamlining processes. When wait times are reduced, products move faster through the supply chain and there is less need to hold excess inventory as a buffer.
