Where a 40-day apparel TAT actually goes, week by week

Ask a factory for a lead time and you get a number. Forty days. Sixty days. The number is not the useful part. What matters is where those days sit, because that tells you which ones you can compress, which ones you cannot, and which ones are in your hands rather than ours.

Here is how a first order of a woven dress programme — say twelve styles, three colourways each, 400 pieces a style — actually spends forty days on our floor in Gurgaon.

Week 1: paper, not cloth

Days 1 to 7 are spent on things that produce nothing you can hold. We read the tech pack properly and come back with questions. We work out the consumption per garment and place the fabric order. We book the knitting or dyeing slot. We raise trims — labels, zips, buttons, thread shades — because a trim arriving late stops a line just as effectively as fabric arriving late, and trims are the thing everybody forgets.

If you have sent a complete tech pack, this week is quiet and quick. If the pack has a fabric described as 'similar to attached' with no attachment, week one becomes week two.

Weeks 2 and 3: fabric, and only fabric

Fabric is sixteen of the forty days and it is the part of the calendar with the least give in it. Greige has to be sourced, dyed to your shade, finished, relaxed and inspected. A mill runs your 3,000 metres alongside somebody else's 30,000 and you do not control the sequence.

This is where lab dips matter more than anyone expects. A lab dip approved on day 9 keeps the calendar. The same lab dip approved on day 16 does not cost you seven days — it costs you the dyeing slot, and the next one is a week later. That is the single most common way a forty-day order becomes a fifty-day order, and it happens on the buyer's side of the table.

While fabric is running we cut and sew the fit sample in a substitute cloth of the same weight and stretch, so fit comments are already resolved by the time bulk fabric lands.

Week 4 and half of week 5: the twelve days of stitching

Cutting, bundling, sewing. Twelve days across 200-odd machines, and the only part of the process that looks like garment manufacture in a photograph. It is also the part with the most slack: if we are late here we can add a line, run an extra hour, or split the order across two floors. We cannot add a dye house.

• Cutting and bundling: 2 days
• Sewing, with inline checking at every operation: 9 days
• End-of-line audit and repairs: 1 day

Surface work — embroidery, print, hand detail — adds about three days, and it happens between cutting and sewing or between sewing and washing depending on the technique. It is the reason a plain shirt and an embroidered one are not the same programme even at the same quantity.

The last nine days: finishing and despatch

Washing, pressing, thread trimming, measurement audit on a statistical sample, tagging, poly-bagging, cartonisation, final AQL inspection, documents. Nine days. Buyers routinely assume this is two.

It is nine because finishing is where errors get caught rather than created, and because a container booking is a fixed date rather than a flexible one. If you want goods on a specific vessel, that vessel — not our floor — sets the real deadline, and we work backwards from it.

So what can actually be compressed?

Three things, in order of usefulness.

1. Repeat the fabric. A repeat order in a shade we have already dyed runs in 12 to 15 days, because sixteen days of the original forty were fabric you have already paid for in time.
2. Approve on the day it is due. Five approvals sit inside a first order — lab dip, fit, trims, pre-production sample, and the pilot run. Each one has a date. Hitting all five is worth more than any amount of pressure applied in week four.
3. Freeze the range earlier than feels comfortable. A style added in week two is a new fabric order, and it takes the whole programme with it.

The factories that miss dates are usually not slow. They agreed to a date that never had the fabric in it.

We quote forty days for a first order because that is what the work takes when nothing goes wrong, with roughly three days of honest buffer in it. If someone quotes you twenty-five for a dyed woven programme from scratch, ask them which of the sixteen fabric days they have removed, and how.
