  1. Which lean tool is used to visually map the flow of materials and information from supplier to customer to identify waste and improvement opportunities?

    Answer: Value Stream Mapping (VSM)

    Value Stream Mapping documents and analyzes the current-state flow of materials and information, then designs a future-state map with waste eliminated.

  2. The lean concept of 'jidoka' (autonomation) refers to:

    Answer: The ability of machines and workers to detect abnormalities and stop production

    Jidoka gives machines and workers the authority and ability to stop production when a defect or abnormality is detected, preventing defects from being passed downstream.

  3. What does 'OEE' (Overall Equipment Effectiveness) measure in a lean environment?

    Answer: The combined effect of availability, performance, and quality on equipment productivity

    OEE = Availability × Performance × Quality, providing a single metric that captures the three primary sources of manufacturing productivity loss.

  4. A '5S' workplace organization program consists of Sort, Set in Order, Shine, Standardize, and:

    Answer: Sustain

    The fifth S — Sustain (Shitsuke) — involves maintaining and embedding the first four steps into the organization's culture and daily work habits.

  5. In a lean system, 'single-minute exchange of die' (SMED) is a technique aimed at:

    Answer: Drastically reducing machine setup and changeover times

    SMED targets reducing changeover times to less than ten minutes (single digit), enabling smaller batch sizes and greater production flexibility.

  6. Which of the following is a characteristic of a lean cellular manufacturing layout?

    Answer: Equipment arranged in a U-shape or flow sequence to enable one-piece flow

    Cellular layouts arrange machines in sequence by process flow (often U-shaped) so products move through all operations with minimal transport and waiting.

  7. The lean principle of 'respect for people' primarily emphasizes:

    Answer: Engaging employees at all levels in problem-solving and continuous improvement

    Respect for people in lean means involving employees in identifying problems and developing solutions, recognizing their knowledge as essential to continuous improvement.
