When to consolidate across departments, and when not to
The most common response to a floor problem is to gather several departments into one order, and it is often the right answer. It is also the answer that gets applied automatically, and the automatic version of it is wrong with some regularity. Consolidation and separation each have a real cost, and the decision turns on what the departments need rather than on the arithmetic alone.
Consolidate when the specification is genuinely shared. If two departments would accept the same item, the same artwork and the same quality without discussion, consolidating them saves a setup, simplifies the delivery, and produces a more accurate reconciliation because one quantity arrives rather than several. It also spreads the floor across more units, which is the part that usually makes the case on price. The condition is that the specification is shared in practice, not only on paper: departments that describe the same requirement in different words will discover the difference at sample approval, which is expensive and late.
Consolidate when the timing is aligned. Two departments that need the goods in the same month can be merged with almost no friction. Two that need them in different months cannot, and forcing them into one order means either storing one department’s items for weeks — an inventory liability, a storage commitment and a chance of loss — or shipping separately anyway, in which case the consolidation saved a setup and added a coordination problem. Timing is the constraint that turns a consolidation from obviously good into obviously bad, and it is usually the last one checked.
Do not consolidate when the item is the point. Where departments have different audiences, different uses or different standards of quality, a single specification is a compromise that serves nobody particularly well. Two functions both wanting something to hand out will end up with an item that is right for one of them, and the other will quietly stop using it. That cost is invisible in the order and permanent in practice, and the right move is usually separate orders at higher per-unit cost — decided explicitly rather than absorbed into a combined quantity.
Do not consolidate ownership by default. A consolidated order has one budget holder, and the moment the quantity is wrong the blame has somewhere specific to land. Departments that did not agree to own the risk tend to discover that they own the outcome. The workable pattern is to agree in advance how surplus is handled, who pays for a re-run, and how the next cycle decides who is in the order — three sentences, agreed once, which is what turns consolidation from a price saving into something departments will join again next time.
