When a request to open a new product code reaches a product committee, it typically arrives with a named justification behind it: a specific chain account asking for dedicated packaging, a technical variant demanded in a particular tender, or a shelf position a competitor has just vacated. The requesting unit is identified, the incremental revenue contribution has been estimated, and the decision closes quickly. The retirement of an existing code rarely appears on the same agenda, since no natural sponsor exists to raise it — no unit's performance measure improves when the portfolio contracts. The portfolio consequently reaches a breadth that no one deliberately selected, assembled entirely out of decisions each of which was, examined on its own terms, defensible.

The same pattern surfaces on two further operational surfaces. During warehouse counts, items showing no movement for twelve months are usually annotated for reassessment in a subsequent period rather than written down or cleared, and as long as the item continues to sit on the balance sheet at cost, deferring the decision imposes no cost on anyone. On the commercial side, whenever a retirement is proposed, a single named customer purchasing that code almost invariably materializes, and the objection is technically accurate — the customer genuinely exists. To the extent that an equivalent objection can be produced for every code in the portfolio, however, the argument stops functioning as evidence about one item and becomes a mechanism that locks the retirement conversation systematically.

This accumulation is what the term SKU proliferation describes — the growth of product code counts at a pace visibly faster than the underlying demand base — and its mechanism originates not in a miscalculation but in the narrow scope of a correct one. Opening a new code is frequently rational in capturing marginal demand, defending shelf position within a channel, and preserving a customer relationship; where incentive structures are built on revenue and account retention, that rationality strengthens further. The difficulty resides not in the individual decision but in the fact that benefit and cost materialize on different time horizons and different accounting surfaces: the benefit appears within the same quarter, attributable to one unit, whereas the cost arrives with a lag, dispersed across the planning desk, the production line, the warehouse racks, and the supply contracts.

The least visible component of that cost sits on the forecasting side. While aggregate demand may remain comparatively stable, dividing the same demand across many codes isolates the variability of each one; because the deviation of combined demand is smaller than the sum of the deviations of its disaggregated parts, the split dissolves the pooling effect, and the total safety stock required to hold service levels constant rises independently of revenue growth. Operationally, this manifests as a thinning of the attention a planner can devote to any single code, a progressive collapse of forecasting into trailing averages, and — precisely for that reason — unanticipated stockouts on the fast-moving items. This is the point at which service levels typically decline as the portfolio widens, at exactly the moment they were expected to improve.

The balance sheet consequence usually hides not in the aggregate size of the inventory line but in its composition. Total inventory turns may appear acceptable while one group of items carries a turnover measured in weeks and another carries one measured in years, the average silently merging two distinct regimes behind a single figure. Working capital tied up in dormant items goes undiscussed because it never appears as an expense, yet it effectively consumes the financing that fast-moving items require, pushing the company into short-term borrowing during seasonal peaks that it would not otherwise need. Unless the provisioning policy is conservative, this burden tends to surface not at year-end close but at the moment a prospective acquirer requests an inventory aging schedule.

Along the sourcing and manufacturing line the cost accumulates in more measurable form. Splitting the same annual volume across many items lowers the per-item volume presented to suppliers, foreclosing access to the upper tiers of price schedules, while MOQ thresholds become binding on an increasing number of items as the portfolio widens — meaning the company purchases more than it requires in order to buy at all. On the production side, each additional variant expresses itself as changeover time, cleaning and validation requirements, a multiplying inventory of packaging and label stock, and, in regulated categories, separate registration and documentation obligations. Because none of these items appear on the justification form supporting the code's creation, a cost layer forms that is invisible at the moment of decision yet paid across the following three years.

At the transaction table this layer is priced explicitly. An acquirer or a lender reads portfolio breadth not as an indicator of market reach but as a question about quality: the share of inventory showing no movement over the trailing twelve months, the tail of the gross margin distribution at code level, and the consistency of the provisioning policy with that tail. In quality-of-earnings work such findings typically translate into an adjustment to normalized EBITDA, and, in the run-up to closing, into a downward revision of the net working capital target; in certain structures, dormant inventory is tied directly to an escrow or a price adjustment mechanism. Weak portfolio governance thereby ceases to be an operational matter and becomes a valuation line item in its own right.

This tendency is neutralized by decision architecture rather than individual discipline, and that architecture has four separable components. The first is gating the creation of a code: a new item is opened either against a paired retirement or against a written justification explaining why pairing is not feasible. The second is carrying the cost of complexity into margin — once changeover, incremental packaging items, safety stock increments, and warehouse footprint are allocated as a per-code coefficient against gross margin, it becomes visible that a portion of the tail contributes negatively in practice. The third is binding review to a rhythm: portfolio screening should operate as a routine embedded in the planning cycle with predefined thresholds, not as an annual exercise. The fourth is the separation of authority, so that the proposing unit, the approving body, and the owner accountable for the code across its life are distinct.

Among these components, the decisive variable is the moment at which the record is created. When the expected annual volume, the expected economic life, and the trigger for retirement — volume remaining below a defined level across a defined period, for instance — are all written into the same document at the time the code is approved, the retirement decision ceases to be a fresh argument opened later and reduces to the enforcement of a threshold already agreed. This is the single structural move that resolves the ownerlessness of retirement, because the person applying the threshold does not personally assume the risk of jeopardizing a customer relationship but merely executes a decision taken collectively in advance. The principle that decision records belong at the moment of proposal rather than the moment of approval translates here into a direct working capital effect.

BEIREK's intervention on this line consists not of rewriting product strategy but of establishing the record and the rhythm by which the portfolio is governed. The lifecycle record is instituted with creation rationale, volume expectation, and retirement threshold held together in one place; a margin view allocating complexity cost per code is constructed and calibrated so that it does not contradict the commercial incentive structure; and portfolio screening is detached from the annual budget exercise and tied to the planning cycle. On the sourcing side, the contractual language is drafted so that MOQ thresholds, changeover cost, and packaging commitments enter the code creation decision as inputs rather than as consequences discovered afterward.

Where a transfer or a financing process is in prospect, the same record performs a different function: with the bridge between the inventory aging schedule and the provisioning policy established beforehand, the acquirer's finding ceases to be a surprise, and the negotiation over the net working capital target rests on a documented base rather than becoming a space in which the counterparty imposes its own assumption. The valuation effect of portfolio rationalization undertaken ahead of closing frequently exceeds that of revenue growth achieved over the same period, since rationalization improves inventory quality and the legibility of the margin distribution simultaneously.

The breadth of a company's product portfolio is, taken alone, neither a signal of strength nor of weakness; what determines its character is whether a closing mechanism exists alongside the opening one. Where retirement has a defined owner, a threshold written in advance, and a functioning rhythm, variety operates as genuine market leverage; where those are absent, the same variety accumulates as inventory on the balance sheet, noise in planning, and discount at the negotiating table.
