Do More With Less: Product Assortment Optimization Is Both Art and Science

Stocking their shelves with the right mix of SKUs is a constant challenge for retailers. Getting it right is critical; getting it wrong can drive away best customers. Graeme McVie offers three tips.

Retailers are always trying to find the right SKU balance. On one hand, they want to maintain a manageable number of SKUs for their merchandising teams. On the other, they want to carry a big enough variety to stay above their competition in the eyes of the customer. Data-driven assortment optimization can win this battle for both sides and make life easier for store staffs while maintaining the best mix to build, and keep, loyal customers.

For instance, the discount chain Dollar General reduced its overall number of SKUs in recent years, expanding some categories and contracting others. “We actually believe we can do more … with less SKUs,” said Rick Dreiling, chairman and CEO. He said the reduction was part of a “work simplification” program to enable managers to focus on location merchandising.

Tracking the right metrics is crucial for understanding three things: the true incremental value of each SKU; the top-priority shoppers; and the categories and items most important to them. Companies considering trimming their SKU mix need to keep in mind that there are smart ways to make sure assortment optimization works and does not drive away the best customers.

Here are three ways to do that.


Know what your best customers are buying.

The traditional way to cut back on products is to rank all items by sales within each category and then cut from the bottom. However, this does not take into account that some low-volume items are valuable to your best customers. Take those items out of the store and some customers could move to a competitor. That is what happened to Walmart in 2010 when an aggressive “SKU rationalization” program eliminated hundreds of items without fully understanding the impact on the company’s best customers. Walmart eventually backtracked and brought back more than 300 SKUs.

Be careful about eliminating products without offering other options.

Some lower-sales items have low transferable sales. If they disappear and an alternative is not offered, the value of the cut items disappears completely. Also, some lower-sales items are part of groups of products often bought together. Lose those items and associated sales could be lost. A good assessment of assortment choices will lay out the financial impact of proposed changes. Technology solutions help retailers quantify the incremental value of each item by looking at three metrics: the demand transferable for each item; the importance of each item to complementary items; and the importance of each item to the most valuable customers.

Focus on strong-performing categories.

Dollar General’s Dreiling said SKU optimization means that instead of “trying to play in every category, really focusing on those that are most productive,” particularly in smaller stores where space is at a premium. Blanket cuts of X percent across all categories can easily result in too many cuts in some categories and too few in others. Some categories simply need more alternatives, and shelf productivity can vary between categories.

As explained in the new LoyaltyOne white paper “Customer-Centric Merchandising,” deep customer-level knowledge, built on advanced analytical techniques, is the foundation for integrated customer-centric retailing and assortment optimization. Knowing the priority customers and how to serve them means leveraging customer-driven insights and identifying the most important categories. It also means clarifying the role that different SKUs play in those categories; understanding how best customers respond to assortments; and then translating strategic decisions into action by removing low-risk, low-productivity items and giving more shelf space to more productive ones.

When assortment optimization is done right, companies see incremental increases in sales of 1 percent to 3 percent, incremental gross profits of 2 percent to 4 percent, better cash flow, faster inventory turns and less working capital tied up in inventory. Most importantly, retailers improve their merchandising without decreasing shopper engagement or business impact – by putting their best customers first.
