Question 1

JIT/LEAN/Lean minimizes production lot sizes.

Accepted Answer

JIT/LEAN manufacturing focuses on reducing waste and inefficiencies in the production process, which includes minimizing production lot sizes to reduce inventory costs and increase flexibility.

Question 2

In order for JIT/LEAN/Lean to bring about all the benefits inherent in its philosophy, it must be part of a total quality system.

Accepted Answer

JIT/LEAN/Lean focuses on reducing waste and improving efficiency, but for it to fully realize its benefits, it needs to be integrated into a total quality system that ensures continuous improvement and quality at every stage of the production process.

Question 3

In a JIT/LEAN/Lean production facility, the supplying process makes product, then stores it until a Kanban from the receiving process notifies the supplying process that product is needed.

Accepted Answer

In a JIT/LEAN production system, the supplying process does not make and store product in advance; it only produces product in response to a Kanban signal from the receiving process, indicating that production is needed. This minimizes inventory and reduces waste.

Question 4

In a JIT/LEAN plant, there is no such thing as a bottleneck.

Accepted Answer

In a JIT/LEAN plant, the goal is to minimize bottlenecks, but they can still exist due to constraints in production processes, equipment limitations, or fluctuations in demand.

Question 5

Automation is being superseded by JIT/LEAN/Lean in manufacturing plants.

Accepted Answer

Automation and JIT/LEAN/Lean are complementary approaches in manufacturing plants, not mutually exclusive. Automation focuses on using machines and technology to perform tasks, while JIT (Just-In-Time) and Lean manufacturing aim at reducing waste and improving efficiency. Both can be integrated to enhance production processes.

Question 6

The JIT/LEAN/Lean &#34;pull&#34; system ensures that:&#10;A) Costs are minimized through &#34;economy of scale.&#34;&#10;B) That the production line will never stop because of a problem&#10;C) Buffer stocks are on hand to prevent line stoppage when a critical machine fails.&#10;D) The internal supplier process does not build product unless told to do so by the internal customer process.

Accepted Answer

The JIT/LEAN/Lean "pull" system is characterized by the principle that a process only produces goods when there is a demand for them from the next process in the production line, effectively making the internal supplier process wait for a signal from the internal customer process before producing more items. This reduces waste and improves efficiency by aligning production closely with demand.

Question 7

Which of the following individuals are identified as the developer of JIT/LEAN/Lean?&#10;A) Eiji Toyoda&#10;B) W. Edwards Deming&#10;C) Taiichi Ohno&#10;D) Henry Ford

Accepted Answer

Taiichi Ohno is credited with developing the Just-In-Time (JIT) and Lean manufacturing methodologies at Toyota.

Question 8

Reduced setup times are essential for:&#10;A) Supporting smaller lot sizes&#10;B) Preventing machine problems&#10;C) Making larger lot sizes possible&#10;D) Reducing machine maintenance time

Accepted Answer

Reduced setup times are essential for supporting smaller lot sizes because they allow for more frequent changes in production without significant downtime, making it feasible to produce smaller quantities of diverse products efficiently.

Question 9

It is critical that machines used in JIT/LEAN/Lean processes are consistent and reliable. Which of the following philosophies are used to assure that?&#10;A) Concurrent engineering&#10;B) Total Productive Maintenance (TPM)&#10;C) If it isn't broken, don't fix it&#10;D) Frequent machine replacement

Accepted Answer

Total Productive Maintenance (TPM) is a philosophy that emphasizes preventive maintenance and proactive maintenance practices to ensure that machines are always available, reliable, and in perfect working condition, which is crucial for JIT (Just-In-Time), LEAN, and other lean processes.

Question 10

Which of the following are NOT consistent with JIT/LEAN/Lean manufacturing?&#10;A) Partnering with suppliers&#10;B) Product flexibility&#10;C) Having environmentally controlled warehouses&#10;D) Elimination of all kinds of waste

Accepted Answer

JIT (Just-In-Time)/LEAN manufacturing focuses on reducing waste and improving efficiency, but it does not necessarily require having environmentally controlled warehouses. This is more about specific storage needs rather than a principle of lean manufacturing. Lean principles emphasize streamlining processes, reducing inventory, and improving flow, rather than specific conditions for storage unless directly impacting waste reduction or process improvement.
