While logistics and supply chain managers tracking Lean operations usually seek to eradicate extra inventory, marketing, and sales programs, which often lead businesses to raise the volume of products they keep in stock, SKU becomes a critical aspect. Big brands with SKU implementation are attaining better evaluation and performance from their inventory with SKU rationalization. The SKU rationalization process has become a definite trend across businesses of all sizes.
The drive towards SKU Rationalization is not in any way new to the system, but in cost-conscious periods, it is getting more scrutiny than ever before. Not so long ago, the Wall Street Journal made a report about industry analysts and executives anticipate larger businesses to scale back on their product assortment by 15%.
Previous research has found that reductions (up to 54%) in the number of low-selling SKUs need not affect perceptions of variety and therefore sales, significantly1. Same Research also indicates that consumers experienced divergent reactions to the reduction in sizes, but they uniformly welcomed the elimination of clutter brought on by the reduction in redundant items.
So, What Defines SKU?
A good definition is given by Investopedia
“A stock keeping unit (SKU) is a product and service identification code for a store or product, often displayed as a machine-readable bar code that helps track the item for inventory. A stock keeping unit (SKU) does not need to be assigned to physical products in inventory”.
Every product or service will have its own unique SKU code so customers/users can quickly identify the difference between products. For instance, a product with two or more different labels should have three different SKU codes. Organizations use SKU rationalization or Production Rationalization to decide what items are worth keeping, eliminated or reduced in their inventory, grounded on historical sales data, weighing the cost of producing and stocking against the benefit of selling each product. Also, SKU code is used in tracking the number of product variants available from a particular brand. It is a kind of inventory optimization.
SKU Rationalization, in short, aids free companies from spending time and money on identifying products that work best. In general, Production Rationalization is in no way a silver bullet but can support to cut excess inventory, improve merchandising, improve the bottom line for businesses, and reduce out-of-stocks.
Too Many SKU’s is Not a Good Thing!
There is a general perception in sales community that, the more SKU’s the better! I hear this all most of the time “we need full range in stock to sell XYX product”, but is this really the case? In reality product range sales depend on two factors:
- Availability of key product and category attributes
- Assortments are brand and flavor
I would like to emphasize the importance of Assortment here, which can be done in many ways. I do it by through ABC Analysis.
Nonetheless, having too much SKUs can turn out to be a complex business operation. Simple because, too many products will lead to having too many suppliers, too much inventory, several data analysis, several buyer, moving hands, machines, storage space and so on….I guess you get the message!
Over the past few decades, the figures obtained from Stock Keeping Units (SKUs) businesses offer has improved tremendously. For instance, in the 1970s, the average grocery store supported 7,000 SKUs. At the moment, the average is more than 40,000. This surge is found to be as a result of several factors, which comprises of the increased popularity of brand extensions of existing products, the emergence of mass customization, individual label brands, shorter product development cycles, and lifecycles.

In its place, businesses modify their Production Rationalization decisions at a level across their network that is meaningful and impactful for their business. It also should not be a One-time adjustment, but a gradual change in strategy. Businesses can approach Production Rationalization as a gradual change in their tactic versus a one-time adjustment in their business plan.

At that point, it may become essential to know which market segment or sales channel to place more emphasis. It is also important to try and identify SKU that would perform better if kept. You may need the collection of data on each SKU, for instance, common pack sizes, demand, and profitability, to help with further narrowing down the project scope.
Align SKU Rationalization Approach Together with Marketing Strategy.
A seller’s collection ought to be consistent with their Marketing Strategy. For example, using retail banners that target large, brand-loyal buyers will possibly entail more SKU variety than a seller targeting smaller and limited income buyers or customers. To successfully eliminate any wrong SKUs, without losing the value to customers, a company needs to try and find one or more of product characteristics as below.
- For Demand:
High stock-out, High shrinkage, High product returns, and High pack size variety.
Erratic demand, Demand declines in recent 1-2 years, and Low consume big shelf spaces.
- For Production:
High defects, High labor processing, High setup time, and Low inventory turns.
- For Supply:
High currency risk, Long lead-time, and Strict import control.
If you need to know and apply these demand/production/supply characteristics, you can consider a product item with definite average sales volume with better lead-time and fluctuation in demand. Also, if you want to retain a product, you need to know all aspects pertaining each item.
