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?

Standard Work
Continuous Flow
Jidoka
Andon

Correct Answer

A. Continuous Flow

Explanation

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.

Standardisation allows for accurate performance benchmarking and thus improvement.

TRUE
FALSE

Correct Answer

A. TRUE

Explanation

Standards drive improvement because we can measure, set benchmarks and improve from them.

What is a visual control tool – often a light – that alerts supervisors to problems on the “gemba”.

Jidoka
Andon
Kanban
Takt Time

Correct Answer

A. Andon

Explanation

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.

Of the three kinds of time we use in Lean, which are measured and can be improved?

Cycle Time
Lead Time
Takt Time
Break Time

Correct Answer(s)

A. Cycle Time
A. Lead Time

Explanation

Cycle Time & Lead Time measured and can be improved; Takt Time is calculated, no measured with a watch.

6.

To calculate takt time you need to know the number of operators and how long the process takes.

TRUE
FALSE

Correct Answer

A. FALSE

Explanation

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.

In this image of a work cell which Lean elements do you see?

Andon
Multi-skilled operators
Waterstrider supplying work-in-process inventory
Counter-clockwise flow

Correct Answer(s)

A. Andon
A. Multi-skilled operators
A. Waterstrider supplying work-in-process inventory
A. Counter-clockwise flow

If the customer demand is 55 service roster assignments in one 8-hour day (no breaks), what is the takt time?

1.2 hours
325 seconds
12 minutes
8.7 minutes

Correct Answer

A. 8.7 minutes

Explanation

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.

_________ is known as the “Father of the Toyota Production System”.

Kachiro Toyoda
Taiichi Ohno
Henry Ford
Edwards Demming

Correct Answer

A. Taiichi Ohno

Explanation

One of his famous quotes is “Without standards there can be no improvement.”

If the cycle time of a process is longer than the takt time for that product, what can you do?

Balance the line by taking work from the long cycle and assigning it to a worker with a shorter cycle
Add workers and split the process between them
Change the product’s takt time
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
A. Add workers and split the process between them

Explanation

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.

In pull / just-in-time / continuous flow systems how does one process “know” that the next process is ready for the product?

Jidoka
Andon
Kanban
Takt Time

Correct Answer

A. Kanban

Explanation

“Kan” means “visual” and “ban” means “card’ – so, “visual card”. Kanban are used to indicate demand / signal production.

The primary difference between Lean standard work and what we traditionally think of as a standardised process is the role of ___________.

Management
Inventory
Controls
Time

Correct Answer

A. Time

Explanation

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.

Time an important element in standard work because Lean is all about doing processes as fast as possible.

TRUE
FALSE

Correct Answer

A. FALSE

Explanation

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.

A spaghetti chart is a tool that shows _________ waste.

Inventory
Waiting
Food
Motion

Correct Answer

A. Motion

Explanation

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.

The goals of establishing a 5S program are to improve the productivity and safety of the work place and increase ____________.

Bonuses
Orders
Staff satisfaction
Inventory

Correct Answer

A. Staff satisfaction

Explanation

An employee with clear procedures working in a clean and safe environment will be happier and more productive that one in a disorganised environment.
