How a home linen maker keeps stock ranges and made-to-order programmes from starving each other.

A stocked range and a made-to-order programme want opposite things from the same plant. Stock wants long, smooth runs that hold the fill rate. Made-to-order wants the plant to interrupt itself for a customer's window. In this archetype they share the greige store, the dye house and the stitching lines, and there is usually no rule for deciding between them — so the decision goes to whoever escalated most recently, which is not the same as whoever is worth most.

Variant complexity makes it worse. A bed linen range multiplies across size, colour, thread count and set composition until a modest catalogue becomes a very large number of distinct stock-keeping units. When the count of variants outgrows the accuracy of the stock record, the plant starts making things it already has and running out of things it thought it had.

Both channels are brought onto one demand plan. Stocked ranges are forecast at the variant level they are actually sold at, and made-to-order programmes are loaded as firm demand against the same capacity — so the plant is planning against everything it owes rather than against one channel at a time.

Fabric allocation then follows a rule rather than a phone call. Greige and dyed fabric are allocated to orders by an agreed priority, which means the trade-off between a fill rate and a customer window becomes a decision the business makes deliberately. Inventory accuracy is rebuilt at variant level, because a demand plan built on an unreliable stock figure is only a more confident guess.

No result is claimed, and a plant that already runs a formal sales-and-operations process will gain less than one that does not. What changes structurally is that the trade-off between the two channels becomes explicit. Instead of an allocation decided by escalation, the plant follows a rule it agreed in advance — and can see afterwards what that rule cost and earned.

The second change is that the stock record becomes trustworthy enough to plan from. Once variants are accurate, the plant stops rebuilding what it already holds and stops promising what it does not — which is where most of the waste in this archetype quietly sits.
