A Data-Driven Framework for SKU Rationalization

Collecting and organizing SKU data

The foundation of any successful SKU Rationalization process lies in collecting and organizing accurate data. Without reliable data, your decisions risk being based on assumptions rather than facts. Start by consolidating information from all relevant sources, such as sales reports, inventory systems, and customer feedback. Ensure the data is clean, consistent, and up-to-date to avoid errors in analysis.

Organize your data into categories that reflect key attributes of your SKUs. These may include sales volume, gross margin, inventory turnover, and customer demand. Using a centralized database or analytics platform can streamline this process, making it easier to access and analyze the data.

Tip: Automate data collection wherever possible to save time and reduce human error. Tools like enterprise resource planning (ERP) systems or inventory management software can simplify this step.

Analyzing SKU performance metrics

Once your data is organized, the next step is to analyze SKU performance using relevant metrics. This analysis helps you identify which products are driving profitability and which are underperforming. Metrics such as sales performance, inventory turnover, and gross margin return on investment (GMROI) provide valuable insights into SKU effectiveness.

The table below highlights some of the most effective metrics for evaluating SKU performance:

Gross Margin Return on Investment	Assesses the profitability of inventory by comparing gross margin to investment, helping prioritize SKUs that generate the most profit.

Advanced analytics, such as machine learning, can further enhance your ability to evaluate SKU performance. Research shows that machine learning models achieve an 83% accuracy rate in classifying SKUs as underperforming, in-line, or overperforming. This level of precision allows you to make informed decisions about which SKUs to retain or discontinue.

Note: Regularly update your performance metrics to reflect current market conditions. This ensures your analysis remains relevant and actionable.

Segmenting SKUs based on strategic value

After analyzing performance metrics, segment your SKUs based on their strategic value. This step helps you prioritize products that align with your business goals, whether it's maximizing profitability, improving customer satisfaction, or streamlining operations.

Demand volume and variability are two critical criteria for segmentation. High-demand SKUs with consistent sales patterns often represent core products that drive revenue. On the other hand, low-demand or highly variable SKUs may require closer scrutiny to determine their value to your portfolio.

For example, you might classify SKUs into three categories:

Core SKUs: High-demand, high-margin products essential to your business.
Niche SKUs: Low-demand but strategically important products that cater to specific customer needs.
Non-essential SKUs: Underperforming products with minimal strategic value.

By segmenting your SKUs, you can allocate resources more effectively and focus on products that contribute the most to your business objectives.

Tip: Use segmentation to guide decisions on inventory levels, marketing efforts, and supply chain priorities. This ensures your strategy remains aligned with your overall goals.

Making informed decisions on SKU retention or discontinuation

Deciding whether to retain or discontinue a SKU requires a structured approach. You must evaluate each product's contribution to your business goals using data-driven insights. This ensures that your decisions are objective and aligned with your strategic priorities.

Start by identifying SKUs that consistently underperform. Look for products with low sales velocity, poor gross margins, or high carrying costs. These SKUs often drain resources without delivering significant value. However, not all underperforming SKUs should be discontinued immediately. Some may serve niche markets or support customer loyalty. For example, a low-demand product might still be essential for retaining a specific customer segment.

To make informed decisions, consider these steps:

Assess Strategic Importance: Determine if the SKU aligns with your long-term goals, such as market expansion or brand differentiation.
Evaluate Financial Impact: Analyze metrics like revenue contribution, profitability, and inventory turnover.
Consult Stakeholders: Collaborate with sales, marketing, and supply chain teams to understand the broader implications of discontinuing a SKU.
Test Alternatives: Before discontinuing a product, explore options like bundling it with high-performing SKUs or repositioning it in the market.
