    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.

  • 3. 

    Lean systems are characterised by ______ operations, paced to ______ demand.

    • Fast; management

    • Stable; customer

    • Stable; management

    • Fast; market

    Correct Answer
    A. Stable; customer
    Explanation
    Lean is not about going fast; it is about stable operations, paced to demand, free of waste with built-in quality.

    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.

    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.

    _________ 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.”

    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.

    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.

    Rate this question:

    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.

    Rate this question:

  • 10. 

    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.

    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.

    Rate this question:

  • 12. 

    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.

    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.

    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.
