A product variant often begins with a reasonable request. A customer needs a different size, finish or configuration, and the organisation can see a commercial reason to offer it. The first order may be manageable. The difficulty develops when that individual accommodation becomes a standing promise of routine availability without another discussion. Years later, the factory is expected to preserve tooling, organise infrequent work and respond quickly to demand that nobody has examined as a complete operating proposition.
I do not regard variety as an operating mistake. It can be central to why customers choose a manufacturer. I do regard its terms as a leadership decision. The institution should understand whether a variant belongs in the standard offer, should be produced against an explicit order or should no longer be quoted for new work. Those are different commercial positions. Treating them as one category can conceal both the value of the range and the work required to sustain it.
The same availability label can conceal different work
Our 2024 review concerned twenty-seven component variants that had accumulated a similar implied availability promise. Their demand patterns and preparation needs were not similar. Nine supported a credible routine offer. Twelve remained relevant but needed a different relationship between the customer order and production commitment. Six no longer justified inclusion in new quotations after the relevant review. The purpose was to make those differences explicit, not to discover the smallest range the plant would find convenient.
The first conversation exposed a familiar division. Commercial colleagues valued the breadth of the offer and worried about losing a reason for the customer to stay. Production colleagues saw repeated interruptions, support requirements and an uncertain sequence. Each side had evidence about a real part of the business. I wanted the decision to connect those accounts. A catalogue entry that looks inexpensive to retain may rely on operating provision elsewhere; a variant that appears troublesome in the schedule may support a relationship worth keeping under different terms.
Moving twelve variants to made-to-order terms was therefore a substantive choice. It preserved a commercial route while changing the promise attached to it. Lead time, preparation and the basis for confirming an order needed to be understood by the people communicating with customers. The phrase made to order could not become an attractive label that left the old expectation untouched. If the customer still expected immediate routine availability, the institution would not have changed the operating problem; it would merely have changed its internal description.
Keeping nine variants standard also required a positive account. The review was not complete once the less convenient work had been categorised. Management needed to understand the provision that supported the standard range and whether the routine promise remained credible. A useful range decision explains what the factory is choosing to support as well as what it is changing. Otherwise the exercise can become a subtraction project whose success is measured only by how many entries disappear.
Change the offer without erasing existing obligations
The six variants removed from new quotations still required examination of existing commitments. A decision about future offers does not cancel a contract, a service responsibility or another obligation the institution has already accepted. Commercial, technical and appropriate advisory owners needed to establish what remained and how it would be handled. I kept that work separate from the catalogue decision so an attractive simplification statement did not imply that every continuing responsibility had ended on the same date.
We recorded JPY 37 million in transition expense for stock treatment, tooling arrangements and the work of changing the offer. That was part of the decision. It would have been misleading to describe the new arrangement as a free release of factory capacity. The institution was paying to make a different promise and to deal responsibly with the consequences of moving from the old one. Some of that work would be commercially uncomfortable, particularly where the customer had become accustomed to terms the business could no longer support routinely.
Sales colleagues objected that an explicit lead-time conversation could weaken a quotation. They were identifying a real consequence, not simply resisting operating discipline. Production colleagues initially favoured reducing the standard range further. I supported the three-part arrangement because it allowed the institution to distinguish between different forms of value. The twelve made-to-order variants did not have to become either routine stock commitments or abandoned opportunities. They could remain in the offer with conditions that both the factory and customer understood.
The communication mattered as much as the classification. People quoting the work needed to know which promise they were authorised to make and when an exception required another decision. An old description in a customer document could recreate the previous obligation even after the planning system had changed. The transition therefore included the way the offer was explained, not merely the internal item status. A range review is unfinished while different parts of the organisation continue to sell and plan different versions of the same product promise.
Discuss the operating promise when the variant is introduced
The experience made me more interested in the first decision about a variant. What demand or relationship justifies it? Which preparation and support conditions will it require? What should happen if demand becomes infrequent? These questions do not need to make every modest customer request into a large approval exercise. They do need a proportionate place in the decision, particularly when the offer is expected to remain available beyond the first order that prompted it.
I would also avoid assuming that every unusual requirement should carry the same commercial response. Some may belong within the institution’s intended service proposition. Others may need a distinct lead time or a discussion about the cost of support. The decision should follow the purpose and operating consequence, with the appropriate commercial authority involved. A factory should be able to explain the work required without acquiring unilateral control over the customer relationship simply because the work is inconvenient.
Reviewing the range at intervals can make change less abrupt. Demand, equipment, tooling and customer needs evolve, and an arrangement that once made sense may require different terms later. The review should preserve the reason for an earlier choice so the institution can understand what has changed. An infrequently ordered variant should not be declared irrelevant merely because a recent period was quiet, nor should a historical success make its operating promise permanent without examination.
I describe our outcome as three clearer promises across twenty-seven variants: nine standard, twelve made to order and six removed from new quotation. Existing obligations and transition expense remained visible. It was not the elimination of the entire group, proof of a permanent saving or a claim that every customer welcomed the change. The more useful result was that variety became discussable as a commercial and operating choice. A catalogue deserves that discipline because its entries eventually become work that real people are expected to schedule, prepare and deliver.
