The Achievement
One of the most meaningful interventions in supply chain operations rarely involves implementing a new system or introducing complex optimisation algorithms. Sometimes the most powerful improvement comes from removing complexity.
In one engagement, approximately fifty-five finished product SKUs were eliminated from the product portfolio. This represented roughly eight percent of the total SKU base at the time.
On paper, that number may appear modest. In practice, it released a significant amount of operational capacity across the supply chain.
Why SKU Proliferation Matters
SKU proliferation is one of the most persistent sources of inefficiency in supply chain operations. Each additional product variant introduces new planning complexity, production changeovers, inventory requirements, procurement orders, and storage obligations.
The operational impact grows in a highly nonlinear manner. Removing a small percentage of SKUs can produce disproportionately large improvements in capacity utilisation and process stability.
Manufacturing lines run longer without interruption. Changeover and setup times decline. Inventory planning becomes simpler. Procurement teams avoid issuing purchase orders for quantities that barely justify administrative effort. Production lot sizes become aligned with actual demand rather than theoretical availability.
Many low-volume SKUs eventually accumulate raw materials and packaging inventory that remain unused for months. These inventories occupy warehouse space, absorb working capital, and eventually risk obsolescence.
In practical terms, these products become operational noise.
The Sales Perspective
The difficulty in addressing SKU proliferation rarely lies in analytical complexity. It lies in organisational dynamics.
Commercial teams often advocate new product variants or packaging changes in response to competitor activity. A competitor launches a new variant, and the instinctive response is to introduce an equivalent offering. The assumption is that product variety increases market coverage.
In many cases, these additional SKUs serve no clearly defined customer segment. They exist because the organisation believes it should have them.
Over time, the portfolio expands incrementally until operational complexity begins to outweigh commercial benefit.
Quantifying the Cost
The turning point in SKU rationalisation occurs when leadership can see the financial consequences clearly.
In this case, the analysis focused on the cost of maintaining the marginal SKUs. Inventory levels of raw materials, packaging components, and finished goods were examined alongside production utilisation and procurement activity. Many items had accumulated inventory that remained unused for extended periods.
Once the financial impact of these inventories became visible, the trade-off analysis shifted. Maintaining a marginal product line was no longer viewed as harmless variety. It became a measurable operational burden.
Importantly, many of these SKUs had existed in the portfolio for more than a decade without anyone questioning their relevance.
The Analytical Method
The technical method used to support the decision was straightforward.
A supply planning simulation was conducted in which the demand associated with the targeted SKUs was removed. The resulting production plan was then analysed to determine how manufacturing capacity utilisation changed across the network.
This simulation revealed the extent to which low-volume products were fragmenting production schedules and forcing inefficient changeovers. Removing them allowed production lines to operate with longer runs and fewer interruptions.
The capacity released through this adjustment could then be reallocated to higher-demand products or used to stabilise production schedules.
The Nonlinear Benefit
The key insight from the exercise was the nonlinear relationship between SKU count and operational efficiency.
Each additional SKU introduces incremental planning complexity, but the operational consequences compound across multiple layers of the supply chain. Production planning, procurement scheduling, inventory management, warehouse operations, and demand forecasting all become more complicated as the portfolio expands.
Reducing the SKU base therefore simplifies the entire system simultaneously.
The Strategic Lesson
SKU rationalisation requires analytical discipline and organisational courage. It demands that leadership confront the trade-off between market variety and operational efficiency.
Not every product deserves to remain in the portfolio indefinitely. Some exist only because they were introduced years ago and never reconsidered.
Supply chain improvement sometimes begins with a simple question: which products should no longer exist?
