Ranges rarely fail because the products are wrong. They fail because the range is wider than the business can carry. Every additional item adds a minimum order quantity, a stock position, a forecast and a decision about what to do when it does not move. Planning the number of items before designing them is the least costly piece of discipline available to a studio or a brand.
Start from the constraint, not the catalogue
The binding constraint is almost always the smallest order a factory will run. A set that contains five components has five order quantities, and they rarely repeat on the same cycle, so the item with the smallest run and the longest lead time sets the rhythm for the whole programme. Counting the components in a proposed range against those numbers, before any artwork is drawn, usually removes two or three items that were never going to earn their shelf space.
How much cover a slow-moving item needs
Stock cover is the number of months of demand held on the shelf. Fast-moving consumables can be ordered closer to demand because they sell through reliably. Durable equipment behaves differently: a mat or a set is bought once and kept for years, so demand is thin and irregular, and holding cover for an item that sells a few units a month only ties up space. The useful rule is to keep deep cover only where a reorder would take longer than the customer is willing to wait.
Lead time belongs in the design
Lead time is not one number. It is sampling, tooling, component production, assembly, packing and freight, and the totals differ between a moulded silicone item and a sewn textile one. When those steps are mapped on a single timeline, it becomes obvious which items must be held in stock ahead of a selling season and which can be made to order. Mixed-material sets are the hardest case, because one late component holds the whole kit and the set cannot ship until the last line is complete. Approval and testing deserve the same treatment: the general safety requirements and test methods that indoor training equipment is expected to meet are set out in the published standard for stationary training equipment, and a testing step discovered late will move a launch date.
Phasing the launch
A practical sequence starts with the item a customer needs first and that the range can supply most reliably, then adds breadth once reorder patterns are visible. Two or three items that complement each other, sold as a set and supported individually, teach more about demand than a broad line launched all at once. Reorder data is the evidence that justifies the next item, and it can only be read if the first phase was narrow enough to produce a pattern. Our pilates product range is organised so that items can be added in stages, the build and testing steps behind a mixed-material set are described under customised programmes, and a launch plan can be discussed through contact.
Frequently asked questions
How many items should a first pilates range include?
Fewer than most plans propose. Start with the two or three items a customer would buy together, confirm that reorder patterns appear, then add breadth using that evidence.
Does a larger order quantity always reduce risk?
No. A larger run lowers the unit effort but raises the amount of stock that has to be carried if demand does not appear. Match the run to the cover the business can hold.
Which item usually sets the launch date?
The component with the longest lead time, not the most important one. In a mixed-material set that is often a moulded part, so its tooling and testing should be scheduled first.
