Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is meant by lean production?

    Model answer

    Lean production is an approach that produces more output using fewer resources. Waste of time, materials, space and effort is removed wherever it is found.

  2. 2

    Where did lean production originate?

    Model answer

    Lean production developed in Japanese car manufacturing after the Second World War. Toyota's production system is the model most often studied.

  3. 3

    Name four types of waste that lean production aims to remove.

    Model answer

    Four types of waste are excess stock, waiting time, unnecessary movement and defective output. Each consumes resources without adding anything a customer will pay for.

  4. 4

    What is kaizen?

    Model answer

    Kaizen means continuous improvement through many small changes rather than one large one. Every employee is expected to suggest improvements to their own work.

  5. 5

    Why are small kaizen improvements often preferred to one large change?

    Model answer

    Small changes cost little, carry little risk and can be introduced immediately. The improvements then accumulate into a large gain over time.

  6. 6

    What is a kaizen group?

    Model answer

    A kaizen group is a small team that meets regularly to find improvements in its own area. Members are the people who actually do the work.
