The order you should not have taken: reading capacity before you commit
The most expensive order in the factory's year is usually one that looked wonderful in the meeting: a big quantity, a decent price, a buyer worth impressing. The cost arrived later, as overtime, air freight, penalties, and the quiet ruin of three other orders that shared the same lines. The order should not have been taken, and the information that would have said so existed at the moment of the handshake. It just was not in the room.
The question the meeting never asks precisely
Can we make it by the date? gets answered with confidence. The precise question has parts: which lines, for how many days, at what efficiency, starting when, and what currently occupies those lines? Vague capacity feels large; specific capacity is a number, and the number is checkable before commitment. A line capacity calculation takes minutes: manpower, working minutes, SMV, a realistic efficiency, and suddenly the heroic quantity has a length in days.
Three lies optimism tells
The efficiency lie. The quote assumes the line's best month, not its measured average. An order priced at 65 percent efficiency on a line that runs 52 will eat its margin in overtime. Plans and quotes should state their efficiency and its source, the discipline we detailed in capacity planning that respects reality.
The empty-calendar lie. The lines look free because the calendar in the meeting shows this order alone. The factory's other commitments, and their habit of running late, are the real backdrop. Capacity is what remains after honesty about existing bookings, not the theoretical total.
The lead-time lie. Ship date minus today is not your production window. Fabric has a lead time, approvals have queues, cutting cannot start before material lands. A lead-time walk-through that runs the calendar backwards from the vessel cutoff often reveals that the sewing window everyone imagined was already gone at signing.
Saying no, and saying yes properly
A factory that can compute its answer gains two abilities. It can decline gracefully and early, with a counter-date that is actually achievable, which buyers respect more than a brave yes followed by a shameful call in week six. And it can accept aggressively when the numbers genuinely close, taking orders competitors refuse out of vague fear, because it knows the difference between tight and impossible.
Make it a gate
The fix is procedural, not heroic: no commitment without a capacity check against real bookings and a backward calendar against real lead times, on paper, before the price is agreed. Ten minutes of arithmetic at the front of an order is the cheapest insurance the commercial team will ever buy. The most profitable sentence in this business remains: we can deliver on the 24th, not the 10th.
