- A.
Fast; management
- B.
Stable; customer
- C.
Stable; management
- D.
Fast; market
Correct Answer
B. Stable; customerExplanation
Lean is not about going fast; it is about stable operations, paced to demand, free of waste with built-in quality.Rate this question:

What is the production system in a Lean operation in which items are processed and moved directly to the next process with each processing step completing its work just before the next process needs the item?
- A.
Standard Work
- B.
Continuous Flow
- C.
Jidoka
- D.
Andon
Correct Answer
B. Continuous FlowExplanation
Continuous Flow is the correct answer because it refers to a production system in Lean operations where items are processed and moved directly to the next process without any delays or interruptions. Each processing step completes its work just before the next process requires the item, ensuring a smooth and continuous flow of work. This helps to minimize waste, reduce lead time, and improve overall efficiency in the production process.Rate this question:

Standardisation allows for accurate performance benchmarking and thus improvement.
- A.
TRUE
- B.
FALSE
Correct Answer
A. TRUEExplanation
Standards drive improvement because we can measure, set benchmarks and improve from them.Rate this question:

What is a visual control tool – often a light – that alerts supervisors to problems on the “gemba”.
- A.
Jidoka
- B.
Andon
- C.
Kanban
- D.
Takt Time
Correct Answer
B. AndonExplanation
Andon is a visual control tool, often a light, that alerts supervisors to problems on the "gemba". It is used in lean manufacturing to signal abnormalities or issues in the production process, allowing for immediate action to be taken. The purpose of Andon is to improve communication, increase efficiency, and promote problem-solving in real-time. It helps supervisors quickly identify and address problems, reducing downtime and improving overall productivity.Rate this question:

Of the three kinds of time we use in Lean, which are measured and can be improved?
- A.
Cycle Time
- B.
Lead Time
- C.
Takt Time
- D.
Break Time
Correct Answer(s)
A. Cycle Time
B. Lead TimeExplanation
Cycle Time & Lead Time measured and can be improved; Takt Time is calculated, no measured with a watch.Rate this question:

To calculate takt time you need to know the number of operators and how long the process takes.
- A.
TRUE
- B.
FALSE
Correct Answer
B. FALSEExplanation
Takt time measures the rate of customer demand. It is INDEPENDENT of capacity, number of worker or productivity – but can be used to calculate these elements.Rate this question:

In this image of a work cell which Lean elements do you see?
- A.
Andon
- B.
Multi-skilled operators
- C.
Waterstrider supplying work-in-process inventory
- D.
Counter-clockwise flow
Correct Answer(s)
A. Andon
B. Multi-skilled operators
C. Waterstrider supplying work-in-process inventory
D. Counter-clockwise flowExplanation
All of these elements are pictured!Rate this question:

If the customer demand is 55 service roster assignments in one 8-hour day (no breaks), what is the takt time?
- A.
1.2 hours
- B.
325 seconds
- C.
12 minutes
- D.
8.7 minutes
Correct Answer
D. 8.7 minutesExplanation
Every 8.7 minutes an assignment must be completed. Knowing this rate of customer demand can help determine staffing levels. The calculation is 8 hours X 60 minutes = 480 minutes / 55 = 8.7.Rate this question:

_________ is known as the “Father of the Toyota Production System”.
- A.
Kachiro Toyoda
- B.
Taiichi Ohno
- C.
Henry Ford
- D.
Edwards Demming
Correct Answer
B. Taiichi OhnoExplanation
One of his famous quotes is “Without standards there can be no improvement.”Rate this question:

If the cycle time of a process is longer than the takt time for that product, what can you do?
- A.
Balance the line by taking work from the long cycle and assigning it to a worker with a shorter cycle
- B.
Add workers and split the process between them
- C.
Change the product’s takt time
- D.
All of the above
Correct Answer(s)
A. Balance the line by taking work from the long cycle and assigning it to a worker with a shorter cycle
B. Add workers and split the process between themExplanation
You should not change the takt time. Lengthening the takt time to accommodate the longer cycle time would mean not meeting customer demand. Ideally you should remove waste and rebalance the work between workers; add workers if necessary.Rate this question:

In pull / just-in-time / continuous flow systems how does one process “know” that the next process is ready for the product?
- A.
Jidoka
- B.
Andon
- C.
Kanban
- D.
Takt Time
Correct Answer
C. KanbanExplanation
“Kan” means “visual” and “ban” means “card’ – so, “visual card”. Kanban are used to indicate demand / signal production.Rate this question:

The primary difference between Lean standard work and what we traditionally think of as a standardised process is the role of ___________.
- A.
Management
- B.
Inventory
- C.
Controls
- D.
Time
Correct Answer
D. TimeExplanation
The primary difference between Lean standard work and traditional standardized processes lies in the role of time. In Lean standard work, time is a crucial factor that is carefully managed and optimized. Lean principles aim to eliminate waste and reduce lead time, ensuring that processes are efficient and streamlined. Traditional standardized processes may not prioritize time management to the same extent, potentially leading to inefficiencies and longer lead times. By focusing on time, Lean standard work can help organizations achieve greater productivity and improve overall performance.Rate this question:
-
- 13.
Time an important element in standard work because Lean is all about doing processes as fast as possible.
- A.
TRUE
- B.
FALSE
Correct Answer
B. FALSEExplanation
In Lean, processes should be paced to customer demand (takt time), NOT made to go as fast as possible. Also, timing standard work allows measurement so we can improve.Rate this question:

A spaghetti chart is a tool that shows _________ waste.
- A.
Inventory
- B.
Waiting
- C.
Food
- D.
Motion
Correct Answer
D. MotionExplanation
A spaghetti chart is a tool that shows motion waste. It is a visual representation of the movement of people or objects within a process or system. By mapping out the paths and interactions, it helps identify areas of unnecessary motion, such as excessive walking, backtracking, or unnecessary handling of materials. This waste can then be eliminated or minimized to improve efficiency and productivity.Rate this question:
