Production schedule explainer

Check four constraints: machine capacity on the required process, material availability including lead time, tooling and changeover time, and labour on that shift with the right skill. Then answer with the trade, naming which existing orders move.

Count the changeovers, since inserting a job between two orders of the same family may cost two setups instead of none. State the setup time explicitly, because it is invisible in the order book and is where capacity is lost.

The four constraints are machine capacity, material availability with lead time, tooling and changeover time, and skilled labour on the relevant shift. The binding constraint is rarely the machine and almost never the one the question assumed.

A yes with no stated consequence hides which orders move and lets the schedule become fiction. The useful answer names the trade, such as which order shifts days or whether Saturday overtime is required.

Refuse when the change cannot be absorbed without overtime or when it would silently move another customer's order. Never promise a date without checking material availability first.
