  1. Which lean principle focuses on eliminating all activities that do not add value from the customer's perspective?

    Answer: Waste elimination (Muda)

    Waste elimination (Muda) is the core lean principle focused on removing all non-value-adding activities from the perspective of the customer.

  2. In the Toyota Production System, what are the three types of waste collectively known as the '3 Ms'?

    Answer: Muda, Mura, Muri

    Muda (waste), Mura (unevenness), and Muri (overburden) are the three types of waste identified in the Toyota Production System.

  3. What does the lean concept of 'Takt time' represent?

    Answer: The rate at which products must be produced to meet customer demand

    Takt time is the available production time divided by customer demand, representing the rate at which products must be completed to satisfy demand.

  4. Which lean tool is used to visually document all the steps involved in delivering a product or service, including both value-added and non-value-added steps?

    Answer: Value stream map

    A value stream map visually documents all process steps from raw material to customer delivery, identifying value-added and non-value-added activities.

  5. What is the primary purpose of a Kanban system in lean manufacturing?

    Answer: To signal replenishment and control work-in-process inventory

    Kanban is a pull-based signaling system used to trigger replenishment and limit work-in-process inventory by authorizing production or movement only when needed.

  6. In the context of lean manufacturing, what are the five principles defined by Womack and Jones in 'Lean Thinking'?

    Answer: Value, Value stream, Flow, Pull, Perfection

    Womack and Jones defined the five lean principles as: specify value, identify the value stream, make value flow, let customers pull value, and pursue perfection.

  7. Which of the following best describes 'One-Piece Flow' in lean manufacturing?

    Answer: Producing items one at a time and moving them immediately to the next step

    One-piece flow means producing and moving one unit at a time through each process step, minimizing work-in-process inventory and exposing quality issues immediately.
