Final answer:
The statement is false, as JIT/lean operations use a pull system of planning where production is driven by customer demand, not forecasts.
Step-by-step explanation:
The ideal scheduling for JIT/lean operations actually follows a pull system of planning, not a push system. In JIT (Just-in-Time) or lean manufacturing, production is based on customer demand rather than forecasting. Materials and products are only moved through the production process as they are needed, which reduces waste and improves efficiency. Therefore, the statement that the ideal scheduling for JIT/lean operations follows a push system of planning is false. This approach allows for greater efficiency and responsiveness to customer needs.
