In LEAN, what does the Pull principle emphasize?

• A. Provide the right amount at the right time—no more, no less.
• B. Pushing production to meet forecasted demand.
• C. Pulling products through the plant regardless of demand.
• D. Using kanban to increase inventory.

Answer: (A)

In Lean, the Pull principle is about starting work only from actual demand, producing what is needed when it is needed and in the exact amount required. This keeps flow smooth and avoids making more than is being consumed, which reduces waste and lowers inventory. Think of it as responding to a signal from the next step or the customer—when consumption or a downstream request occurs, the upstream process pulls just enough to meet that need. Kanban is often used as that signaling mechanism, helping teams replenish only what has been used rather than forecasting far ahead. So the statement that best fits is producing the right amount at the right time—no more, no less. The other ideas describe pushing based on forecasts, pulling regardless of demand, or using signals to raise inventory, which contradicts the pull mindset.
