Read the first 7 Lean Principles and Foundations flashcards as text

  1. Which of the following statements about the Toyota Production System (TPS) is correct?

    Answer: TPS is the foundational system from which modern lean thinking evolved

    The Toyota Production System, developed by Taiichi Ohno and Shigeo Shingo, is the original lean manufacturing system that served as the basis for lean thinking worldwide.

  2. In lean, 'Andon' refers to:

    Answer: A visual signal system that alerts the team to a problem requiring attention

    Andon is a visual management tool — typically a light or board — that signals abnormal conditions on the production floor so problems can be addressed immediately.

  3. A lean team wants to reduce unnecessary inventory between two process steps. Which tool would they most likely implement?

    Answer: Kanban

    Kanban is a visual pull system that limits work-in-process inventory by only allowing upstream steps to produce when a downstream step signals it is ready to receive more.

  4. Which lean principle requires identifying what the customer considers valuable before designing processes?

    Answer: Identify Value

    The first of Womack and Jones's five lean principles is to precisely define value from the customer's perspective before any process improvement begins.

  5. Poka-yoke devices are used in lean to:

    Answer: Prevent defects by making errors impossible or immediately detectable

    Poka-yoke (mistake-proofing) uses mechanisms that prevent errors from occurring or immediately detect them when they do, stopping defects at the source.

  6. In lean terminology, 'WIP' (Work-In-Process) is generally considered a form of waste because:

    Answer: It represents inventory that has consumed resources but not yet delivered value to the customer

    WIP is a form of inventory waste — capital and materials have been consumed, but no value has yet been delivered to the customer, tying up resources and hiding problems.

  7. Which of the following is the correct sequence for implementing lean according to the five principles of Womack and Jones?

    Answer: Value → Value Stream → Flow → Pull → Perfection

    The correct sequence is: (1) Identify Value, (2) Map the Value Stream, (3) Create Flow, (4) Establish Pull, (5) Seek Perfection.
