Question 1

According to the conceptual framework of JIT, there are 8 practices considered essential for a comprehensive JIT implementation.At the same time, there are two additional practices which constitute the foundation of all 8 activities.List these two additional practices.

Accepted Answer

Concurrent problem solving, performance measuring

Question 2

Which of the following is a correct paper kaizen guidelines?
A) Do not include automation as a factor for the work elements
B) Do not include any breaks for operators as work elements
C) Do not include any cycle work for operators as work elements
D) Do not include any walking as a work element.

Accepted Answer

Including walking as a work element can help identify inefficiencies in the layout of the workplace and lead to improvements in workflow. On the other hand, not including breaks or cycle work for operators can lead to unrealistic and unsustainable improvement goals. Not including automation as a factor for the work elements may also limit the potential for improvement in processes that can benefit from automation.

Question 3

When done properly, the implementation of Just in time (JIT)philosophy increases the company's performance.Choose the effects that do not contribute to this phenomenon.
1)Increases supplier dependency
2)Reduces the need for information sharing
3)Increases WIP Inventory levels
4)Reduces process variability
A) (1)
B) (1), (2) and (4)
C) (3) and (4)
D) (1), (2) and (3)

Accepted Answer

Just in Time (JIT) philosophy aims to reduce inventory levels, including Work in Process (WIP) inventory, and enhance efficiency through closer relationships and information sharing with suppliers. It does not aim to reduce the need for information sharing or increase supplier dependency. Reducing process variability is actually a goal of JIT to improve performance.

Question 4

In one sentence, describe the basic underlining concept of Just in time (JIT)manufacturing.

Accepted Answer

The answer of In one sentence, describe the basic underlining...

Question 5

The following are some of the requirements of Supplier Development.Which are not correct?
1)Focus on inspections after receipt
2)Implement judoka program
3)Reduce supplier lead times
4)Require frequent deliveries
A) (1)
B) (2) and (3)
C) (3) and (4)
D) None of the above

Accepted Answer

The requirement "Focus on inspections after receipt" is not correct. A focus on inspections after receipt is a reactive approach, whereas supplier development requires a proactive approach to address issues before they occur. The other requirements such as implementing a judoka program, reducing supplier lead times, and requiring frequent deliveries are all valid and beneficial aspects of supplier development.

Question 6

Choose an option that does not correctly fill in the blanks.
-While there are many different definitions of lean manufacturing, lean can also be described as a set of manufacturing practices bundles including _____________ and _________________.
A) Just-in-time (JIT)/Total quality management (TQM)
B) Human resource management (HRM)/Just-in-time (JIT)
C) Total process management (TPM) /Human resource management (HRM)
D) total productive maintenance (TPM)/Just-in-time (JIT)

Accepted Answer

Lean manufacturing focuses on efficiency and waste reduction, typically involving practices like Just-in-Time (JIT), Total Quality Management (TQM), and Total Productive Maintenance (TPM). Human Resource Management (HRM), while important, is not specifically a lean manufacturing practice.

Question 7

Evidence has shown that the implementation of Just in time (JIT)philosophy is most successful in a ________________ environment.Fill in the blanks with the correct answers.
A) Repetitive manufacturing
B) Project
C) Custom product
D) Software development

Accepted Answer

Just in time (JIT) philosophy is most successful in a repetitive manufacturing environment where the production processes are standardized and streamlined. JIT is based on the principle of producing only when needed and in the quantity required, which is best suited for repetitive manufacturing as it helps improve efficiency, reduce waste, and minimize inventory levels. It may not be as effective in a project or custom product environment, where the production processes are varied and often unpredictable. Software development is a different kind of production process and may not be suitable for JIT implementation.

Question 8

JIT purchasing can reduce some of the many activities that is required with traditional purchasing.Which of the following activities are less likely to be affected by JIT purchasing?
1)Negotiation
2)Expediting
3)Receiving Inspection
4)Open-Order Status Paperwork
A) (2) and (4)
B) (1) and (4)
C) (1)
D) (3) and (4)

Accepted Answer

Negotiation is less likely to be affected by JIT purchasing because it is a strategic activity focused on establishing terms and conditions, as well as prices with suppliers, which remains crucial regardless of the purchasing model. JIT aims to minimize inventory and streamline processes, but the need for effective negotiation with suppliers to ensure timely delivery and cost efficiency remains unchanged.

Question 9

Which of the following concepts are not associated with lean?
1)Pull
2)Kanban
3)Muda (Waste)
4)Kaizen
A) (1)
B) (2) and (3)
C) (2), (3) and (4)
D) None of the above

Accepted Answer

All the listed concepts (Pull, Kanban, Muda (Waste), Kaizen) are associated with lean methodology, focusing on waste reduction and efficiency improvement.

Question 11

The implementation of JIT moves beyond an adoption of a tool set.It is a organization wide philosophical change.One method of managing change is the Kotter's 8 Steps.Which of the following is not included in Kotter's 8 Steps as a step?
A) Create a sense of urgency
B) Communicate for understanding and buy-in
C) Put together the guiding team
D) Produce long-term wins

Accepted Answer

All four options are part of Kotter's 8 Steps, but one step that is not included in the list is "Celebrate small wins." The correct answer, therefore, is D, which asks for Long-Term Wins.

Question 12

With the increase of lean and JIT popularity, the number of attempts to implement them has increased.At the same time, a significant portion of these attempts have not been successful.Some of the well-known reasons for these failures are _____________ and ________________.Fill in the blanks correctly.

Question 13

What is a proper description of a Kaizen Event?
1)An activity associated with identifying hidden wastes
2)An activity associated with cross functional moral building
3)An activity associated with increasing sales performance
4)An activity associated with maintenance scheduling
A) (2)
B) (3) and (4)
C) (1)
D) (1) and (2)

Accepted Answer

A Kaizen Event is an activity associated with identifying hidden wastes, which is described in option C. The other options are not accurate descriptions of a Kaizen Event.

Question 14

Among the following choices, select the ones that is closely associated with Just in time (JIT)philosophy.
1)SPC
2)MRP II
3)Concurrent problem solving
4)Push manufacturing
A) (1) and (4)
B) (2)
C) (3) and (4)
D) (3)

Accepted Answer

Just in Time (JIT) philosophy emphasizes reducing in-process inventory and associated carrying costs, aiming to improve return on investment by reducing non-value-added activities. It involves producing only what is needed, when it is needed. Concurrent problem solving is a practice aligned with JIT, as it involves solving problems as they occur, preventing delays and reducing waste, which is central to JIT's goals. SPC (Statistical Process Control) is more about quality control, MRP II (Manufacturing Resource Planning) focuses on planning all resources of a manufacturing company, and Push manufacturing is contrary to JIT, as it involves producing goods in anticipation of demand rather than in response to it.

Question 15

Depending on person being asked, the perception of JIT differs.Choose the perceptions that are not commonly associated with JIT.
1)Variant of a conventional reorder-point system
2)Also known as the Lean production
3)A periodic system with fixed lot size
4)A sophisticated Pull system
A) (1)
B) (3)
C) (2) and (4)
D) (1) and (4)

Accepted Answer

Perceptions commonly associated with JIT include (2) and (4), which describe it as a Lean production process and a sophisticated Pull system, respectively. (1) and (3) are not typically seen as accurate descriptions of JIT. JIT is not simply a variant of a conventional reorder-point system (1), but rather a comprehensive approach to eliminating waste and optimizing production flow. Similarly, JIT does not require a fixed lot size, as it aims to produce only what is necessary in the moment, rather than creating excess inventory that may not be needed (3). Therefore, the best choice is B, only option (3) is not commonly associated with JIT.

Question 16

There are 8 types of lean waste.Which of following is not a clear example of motion waste?
A) The location of the office fax machine is across the hall. Every time you are expecting a fax, you need to pass several offices to get it.
B) The process of connecting to the school website takes 8 steps compared to the normal 3 steps.
C) The TV remote is kept on top of the TV and not near the TV viewing couch
D) The office staple is never kept at the same location twice.

Accepted Answer

Motion waste refers to unnecessary movements of people or equipment that do not add value to a process. Choice B describes a process inefficiency related to the number of steps to achieve a task, which is more closely related to process waste, not motion waste. Choices A, C, and D involve unnecessary physical movement, fitting the definition of motion waste.

Question 17

Which of the following situations are likely to happen to the suppliers with implementation of JIT or lean?
1)The buyer will only use a limited number of suppliers
2)Most contracts will be based on long term goals
3)The suppliers are more likely to be subjected to reverse auctions
4)The focus of JIT relationships will be on reducing supplier power in the relationship
A) (1)
B) (3) and (4)
C) (1) and (2)
D) (1), (2) and (4)

Accepted Answer

In the implementation of JIT or lean, the focus is on reducing waste and increasing efficiency, which often involves establishing strong relationships with limited suppliers who can provide high-quality products in a timely manner. Therefore, choice (1) is likely to happen. Additionally, long-term contracts are often preferred over short-term contracts as they provide stability and allow suppliers to plan production accordingly. This makes choice (2) likely to occur as well. However, the implementation of JIT or lean does not necessarily result in reverse auctions or a decrease in supplier power, so choices (3) and (4) are less likely to happen.

Question 18

Practices such as ____________ are associated with Just in time (JIT)philosophy.However, practices such as ________________ are contradictive to JIT.Fill in the blanks with the correct answers.
A) Small lots/Uniform production
B) Uniform production/Preventive maintenance
C) Inspections at arrival / Preventive maintenance
D) Small lots / Inspections at arrival

Accepted Answer

Just in Time (JIT) philosophy emphasizes reducing waste and improving efficiency. Small lots are preferred in JIT to reduce inventory costs and increase flexibility. Inspections at arrival, however, contradict JIT principles because JIT relies on quality being built into the process, not inspected in, aiming for a partnership with suppliers that ensures quality before arrival.

Question 19

Uniform Production is an element of JIT production which requires _________________ .Choose an option that does not fill in the blank correctly.
A) Establish freeze windows
B) Level schedules
C) Reduces WIP Inventory levels
D) Under-utilize capacity

Accepted Answer

The answer of Uniform Production is an element of JIT...

Question 20

Which of the following Japanese terms are not associated with JIT?
A) Muda
B) Kanban
C) Heijunka
D) Kenji

Accepted Answer

"Kenji" is not a term associated with JIT. Muda refers to waste elimination, Kanban refers to visual signals for production, and Heijunka refers to production leveling.
