Every export order behaves like its own small project, with dozens of tasks — sampling, fabric booking, trim sourcing, testing — some dependent on each other, some running in parallel. Skipping proper preparation doesn't just risk a slow start; a delay in one early task (like fabric approval) pushes back every task that depends on it, all the way to the shipment date.
Purchase order quantity, sizes, colours, delivery date, and any special instructions are confirmed and understood by every department involved.
The buyer's approved sample and spec sheet are the reference every later stage checks against — production shouldn't start without them finalised.
Fabric, trims, and accessories are confirmed as booked, tested, and in-house (or with a confirmed arrival date) before cutting is scheduled.
Machines, manpower, and line capacity are checked against the order's requirements before it's loaded onto a specific line.
A T&A calendar (also called a TNA, or critical path) is a merchandiser's master schedule for one order — every key task listed with a planned date, an actual date, and who owns it. It typically covers everything from lab dip approval and fit sample dates through to cutting start, sewing completion, and final shipment.
The most useful part of a T&A isn't the list itself, but the critical path — the longest chain of dependent tasks that directly determines the earliest possible delivery date. A delay anywhere on that specific chain delays the shipment; a delay on a task that isn't on the critical path often doesn't, because other work can continue in parallel.
