5 Reasons Garment Factories Miss Ship Dates (and What Changes Each One)

On-time delivery hides the cost

Most factories ship most orders on time. What the on-time number does not show is how: the board reshuffled every afternoon, the overtime, the changeovers nobody planned, the air freight. Those are paid for even when the goods ship.

Late shipments, and the cost of avoiding them, usually come from five causes that feed each other.

1. The fabric date was never achievable

The plan is built on the fabric date the mill was asked for, not the date the mill can deliver. When the fabric does not arrive, the line is waiting, the order is moved, and three other orders move with it.

What changes it: the plan holds every order until its fabric and trims are in-house and its approvals are done, using the dates the factory actually has. The order is placed where it can really start. And the gap between the date asked for and the date delivered stays visible, order by order, so a supplier lead-time problem shows up as a pattern rather than a surprise every month.

2. Lines are loaded at an efficiency they never hit

Lines are planned at the efficiency the plant wants. They run at the one they achieve. The difference becomes overtime, then late orders, on a plan that looked fine when it was issued.

What changes it: the plan uses the efficiency each line achieves on each product group, from the factory's own history. Nothing is loaded past what the line can produce.

3. Only the next few weeks are planned

Placing orders by hand is slow, so the near horizon is planned and the rest of the book waits. When the planner reaches it, the far horizon is already crowded and orders are squeezed in with shortcuts.

What changes it: the whole order book is planned, near and far, every time. Every order has a line and a date from the day it is uploaded, so an order that does not fit is known before it is confirmed to the buyer, not weeks later.

4. Every change knocks on, so nobody replans

A buyer moves a date. To make room, other orders move, and they move others. After a few rounds the floor stops trusting the board, and the plan is only touched once a week. In between, the week is spent reacting.

What changes it: replanning the whole book in minutes, on the same rules, so it can be done every morning after the production update. The same order book always gives the same plan, so the board changes only because something in the book changed.

5. Late orders are found too late

An order is "on track" until the week it ships. By then the only options are the expensive ones.

What changes it: every order that cannot ship on time is named on the day the order book is uploaded, with the reason: capacity before the ship date, fabric not in, an approval not done. That gives the planner and the merchandiser weeks, not days, to act. What to do (talk to the buyer, chase the mill, add a shift) is their decision; the plan's job is to make it plain and early.

How they compound

Late fabric delays the start. The line was loaded above its real efficiency, so there is no slack. The far horizon was never planned, so there is nowhere to move the order. Replanning takes a day, so nobody does it. And nobody knew it would be late until the week it shipped.

Each cause on its own is manageable. Together they produce the familiar week of firefighting.

The bottom line

Better planners are not the answer; most garment planners are remarkably good at managing complexity with tools that do not fit the job. The answer is a plan that already contains the things that break it, built on the factory's own numbers, covering the whole book, rebuilt every morning, with late orders named early. That is what LoadIt does: it plans every order to ship on time, on the line that runs it best, with no capacity left on the table. LoadIt builds the plan. The planner executes it.
