In the dynamic world of consumer goods manufacturing, companies face an escalating challenge that silently erodes profitability and operational efficiency: Stock Keeping Unit (SKU) proliferation. As product portfolios expand to meet diverse customer preferences and market demands, organizations often find themselves managing an unwieldy number of product variations. The first critical step in addressing this complex issue lies in the recognize phase, a fundamental component of lean six sigma methodology that helps businesses identify and understand the true extent of their SKU-related challenges.
Understanding SKU Proliferation in Consumer Goods
SKU proliferation occurs when a manufacturer’s product catalog grows beyond optimal levels, creating redundancies, inefficiencies, and increased operational complexity. While offering variety can capture market share and satisfy customer preferences, unchecked growth in product variations often leads to diminishing returns. Consumer goods companies frequently struggle with hundreds or even thousands of SKUs, many of which contribute minimally to revenue while consuming disproportionate resources.

The phenomenon typically emerges from well-intentioned business decisions. Marketing teams introduce new flavors or package sizes to attract different customer segments. Sales departments request specialized products for key accounts. Regional managers demand localized variations to compete in specific markets. Over time, these incremental additions compound into a sprawling portfolio that strains manufacturing capacity, inflates inventory costs, and complicates supply chain management.

The Strategic Importance of the Recognize Phase
The recognize phase serves as the foundation for any successful SKU rationalization initiative. Within the lean six sigma framework, this initial stage involves systematically identifying problems, gathering preliminary data, and establishing a clear understanding of the current state. Without proper recognition of SKU proliferation and its impacts, organizations cannot develop effective strategies to address the underlying issues.

Many consumer goods manufacturers operate for years without fully acknowledging the hidden costs associated with excessive product variety. The recognize phase brings these challenges into sharp focus, enabling leadership teams to make informed decisions about portfolio optimization. This awareness-building process is essential because SKU proliferation costs often hide within various budget categories rather than appearing as a single line item that triggers immediate concern.
Key Symptoms Indicating SKU Proliferation Problems
Recognizing SKU proliferation requires vigilance in monitoring specific operational and financial indicators. Consumer goods manufacturers should watch for several warning signs that suggest their product portfolio has grown beyond manageable levels.
Declining Profitability Despite Revenue Growth
When a company experiences increasing sales but stagnant or declining profit margins, SKU proliferation may be the culprit. The costs of producing, storing, and distributing numerous low-volume products can easily outweigh the incremental revenue they generate. Manufacturing runs become shorter and less efficient, setup times increase, and economies of scale diminish across the portfolio.
Increased Inventory Carrying Costs
An expanding SKU count directly impacts inventory requirements throughout the supply chain. Warehouses must stock more raw materials, work-in-progress items, and finished goods. This proliferation ties up working capital, increases storage expenses, and raises the risk of obsolescence. Companies in the recognize phase often discover that a significant portion of their inventory consists of slow-moving or dormant SKUs that rarely sell.
Production Complexity and Inefficiency
Manufacturing facilities experience mounting challenges as SKU counts grow. Frequent changeovers between product variations reduce overall equipment effectiveness and throughput. Production planners struggle to optimize schedules, leading to longer lead times and reduced flexibility. Quality control becomes more complicated as staff must monitor specifications for numerous products, increasing the likelihood of errors.
Supply Chain Complications
Forecasting accuracy typically deteriorates as SKU counts increase, particularly for low-volume items with erratic demand patterns. This forecasting difficulty creates ripple effects throughout procurement, production planning, and distribution. Supplier relationships become strained when dealing with numerous component variations, and transportation costs rise due to less-than-optimal loading patterns.
Implementing the Recognize Phase Using Lean Six Sigma Principles
The lean six sigma methodology provides a structured approach to the recognize phase, ensuring that organizations gather relevant information systematically and objectively. This disciplined process prevents rushed judgments and ensures stakeholder buy-in for subsequent rationalization efforts.
Assembling the Right Team
Successful recognition requires input from multiple functional areas. A cross-functional team should include representatives from sales, marketing, operations, finance, and supply chain management. Each perspective contributes unique insights into how SKU proliferation affects different aspects of the business. The team should report to a senior sponsor who can allocate resources and remove organizational barriers.
Data Collection and Analysis
The recognize phase demands comprehensive data gathering across multiple dimensions. Teams should compile information on sales volume, revenue contribution, profit margins, production frequency, inventory levels, and customer importance for each SKU. This quantitative foundation enables objective evaluation rather than relying on anecdotal evidence or departmental preferences.
Advanced analytics tools can help visualize portfolio performance, revealing patterns that might otherwise remain hidden. Pareto analysis often demonstrates that a small percentage of SKUs generates the majority of revenue and profit, while a long tail of products contributes minimally despite consuming substantial resources. Distribution curves, contribution margins, and trend analyses provide additional insights into portfolio health.
Calculating Hidden Costs
One critical element of the recognize phase involves quantifying the true cost of SKU complexity. Standard accounting methods often fail to capture the full impact because complexity costs are distributed across overhead categories. Activity-based costing techniques can help attribute expenses more accurately to individual products, revealing which SKUs actually generate profit versus those that destroy value.
Consumer goods manufacturers should examine costs related to product development, regulatory compliance, quality testing, procurement, production setup, inventory carrying, warehouse space, distribution, and promotional activities. When these expenses are properly allocated, many supposedly profitable SKUs reveal themselves as value destroyers.
Common Challenges During the Recognize Phase
Organizations frequently encounter resistance when attempting to acknowledge and quantify SKU proliferation problems. Understanding these obstacles helps teams prepare strategies to overcome them.
Organizational Silos and Conflicting Priorities
Different departments often have competing interests regarding product portfolio decisions. Sales teams resist SKU reductions, fearing customer dissatisfaction and lost revenue. Marketing departments view variety as essential for brand positioning. Operations teams struggle with complexity but may lack influence in portfolio decisions. Breaking through these silos requires strong leadership commitment and clear communication about company-wide impacts.
Data Quality and Availability Issues
Many consumer goods companies discover that their data systems cannot easily provide the information needed for comprehensive SKU analysis. Sales data may exist in one system, cost information in another, and inventory data in yet another platform. Reconciling these sources and ensuring data accuracy can prove time-consuming but remains essential for credible recognition.
Emotional Attachments to Products
Product managers and executives often develop emotional connections to specific SKUs, particularly those they championed or those representing innovative ideas. These attachments can cloud objective assessment during the recognize phase. The lean six sigma approach helps by emphasizing data-driven decision-making rather than subjective opinions.
Moving Forward After Recognition
Completing the recognize phase creates momentum for addressing SKU proliferation systematically. With clear documentation of the problem’s scope and impact, organizations can proceed to subsequent lean six sigma phases: define, measure, analyze, improve, and control. The recognition work provides the business case for investing time and resources in portfolio rationalization.
Consumer goods manufacturers that successfully navigate the recognize phase position themselves for significant operational improvements. They gain clarity about which products truly drive value, where complexity costs accumulate, and how portfolio decisions affect overall business performance. This foundation enables confident decision-making in subsequent phases, ultimately leading to a leaner, more profitable product portfolio that better serves both customers and shareholders.
The journey toward optimal SKU management begins with recognition. By applying lean six sigma principles during this critical first phase, consumer goods manufacturers transform vague concerns about product complexity into concrete understanding supported by data. This transformation marks the essential first step toward building a more efficient, profitable, and sustainable business model in an increasingly competitive marketplace.
