Capacity is unclear

Understand available capacity before promising new work.

01 · What is usually happening?

Sales asks whether the factory can take another order, and the answer is a guess. Nobody has a number for how many hours each machine has free, so the plant is either over-promised or under-used.

Both mistakes cost money, and neither shows until the month is over.

The question people usually ask“Can we take this order?”
The more useful question“How many hours does each machine or cell have free, and for which jobs?”
