Which principle is NOT involved in pull scheduling within Lean methodology?

Pull scheduling within Lean methodology is fundamentally about responding to actual customer demand rather than forecasting or producing based on predicted needs. The principle that production occurs regardless of demand stands out as incorrect in this context, as it contradicts the very essence of pull scheduling.

In a pull system, production is triggered by specific customer requests or consumption signals. This ensures that resources are only utilized when there is a demand, thereby preventing overproduction, which is a significant waste in Lean. The principles involved in pull scheduling emphasize minimizing inventory levels, as this approach seeks to keep only what is necessary for immediate production and sales, thus reducing holding costs and waste. Additionally, processes must be flexible, allowing for quick adjustments to changes in demand to maintain efficiency and responsiveness.

Therefore, the accurate identification of the principle that does not align with pull scheduling is that production occurs regardless of demand, as it fundamentally opposes the reactive nature of a pull system aiming to optimize resource use based on actual needs.
