The ROI of RFID in the Supply Chain

Although RFID implementations are not without costs and risks, a number of companies in manufacturing, warehousing and distribution and retailing have achieved a 200 percent return on investment.

How Are The Benefits Realized?
RFID can deliver tangible benefits for many types of enterprise businesses:
  • Warehouse and Distribution Productivity—Companies can replace the point-and-read, labor-intensive process of tracking pallets, cases, cartons and individual products with an RFID process. RFID sensors can track these items as they move from various key locations. Because the process is automated, labor costs can be reduced, improving productivity, and enabling the reallocation of resources for more strategic tasks and better scale operations. Productivity improvements can be significant, delivering realized labor costs reductions of 7.5 percent or more in warehouse applications, and 5 to 40 percent in regional distribution centers. For example, as cited in an article appearing in World Trade Magazine ("RFID: Taking Stock of the Wal-Mart Pilot," by N. Shister), Wal-Mart experienced a dramatic reduction of pallet-build from an existing 90 seconds to an even faster 11 seconds—a reduction of almost 90 percent.
  • Retail and Point-of-Sale Productivity—The use of RFID at the product level can help retailers reduce the labor costs and service fees of regular stock management and store-shelf inventory. As one example, handling out-of-stock restocking and replenishment tasks can be reduced by 15 percent to 20 percent with RFID.
  • Out-Of-Stocks—When an item is out-of-stock, 20 percent of the time the customer either does not buy it or else buys a competitive product (according to Jon C. Stine, Intel Retail Consumer Package Goods: Industry Field Primer, Oct. 28, 2005). In grocery stores, as much as 8.3 percent of revenue is lost each year due to out-of-stock conditions, according to the Food Business Forum, the Food Marketing Institute and the Grocery Manufacturers of America. In broader studies of the retail marketplace, the overall economic impact is estimated to be $69 billion in lost revenue due to out-of-stocks (Emory University, the University of St. Gallen and the University Of Colorado, "Retail Out of Stocks: A Worldwide Examination of Extent, Causes and Consumer Response"). Eliminating out-of-stock conditions via better RFID product tracking, inventory visibility and forecasting can have an immediate impact on top-line revenue by retaining lost sales and recapturing lost market share. AMR Research, of Boston, suggests item-level RFID tagging can yield significant benefits today if managed correctly. When targeted at specific consumer goods categories, item-level tagging can yield an astounding 50 percent improvement in stock availability (see "RFID and Retail: Little Return for Case and Pallet Tagging by Scott Langdoc and Kara Romanow). And the benefits are not isolated just to select consumer goods. RFID is proven to deliver an average 16 percent reduction in product out-of-stocks (see EPC Reduces Out-of-Stocks at Wal-Mart). If an out-of stock does occur, RFID enables a retailer to restock three times faster than non-tagged items are restocked within the same store. At the retail level, out-of-stock savings can yield a 3 to 4 percent increase/recapture of sales, according to a 2003 Ernst & Young report, "Study of Retail Loss Prevention."
  • Inventory Management—Inventory accuracy is important to help improve visibility and insight into what specific raw materials have arrived, helping to assure the right materials are available and to better manage just-in-time production models, track work-in-process and speed finished goods through the supply chain. The use of RFID improves these processes and helps minimize costly inventory errors, reducing production delays and lowering production reconfiguration costs that often result from material or demand-planning issues. Additionally, visibility can be improved into distribution and retail channels to track delivered goods more accurately and in real time, and to manage and match demand better. Accurate and real-time visibility throughout the supply chain helps to improve inventory forecasting, manage just-in-time workflow and eliminate excess inventory. Savings are realized by reducing required inventory via lower safety stock requirements, a net 10 to 30 percent savings, according to a 2003 Accenture report, "Auto-ID on Demand: The Value of Auto-ID Technology in Consumer Packaged Goods Demand Planning." Better inventory management also leads to proportional reductions in out-of-stock, lower inventory carry costs and reduced write-downs on obsolete inventory.
  • Shrinkage—Losses due to theft are estimated to cost retailers over $30 billion per year, and are estimated conservatively at 1.7 percent of overall sales, according to Ernst & Young. With RFID, pallets, cartons and individual products can be tracked through the supply chain to pinpoint product location and eliminate inventory errors that can cause shipments to go missing. Better yet, it enables one to find where in the process the product was lost. AMR Research's Langdoc and Romanow estimate an 18 percent average reduction in shrinkage using RFID.
  • Supply Chain Errors—By replacing manual bar-code scanning with automated RFID information capture, one can eliminate data-entry errors, reducing not only inventory and tracking mistakes, but also the costly labor required to resolve such mistakes. Additionally, because RFID automates data entry, more collection and tracking can occur throughout the process, helping to pinpoint asset location and workflow more specifically. And not just labor costs are driven higher by mistakes—retailers and manufacturers each lose $2 million for every $1 billion in sales due to bad data. The prediction is that eliminating bad data could save $10 billion per year, according to 2003 report by A.T. Kearney ("RFID/EPC: Managing the Transition").
  • Capital Asset-Tracking and Management—In many businesses, important assets such as shop equipment and containers are often difficult to track, maintain and secure. RFID can be used effectively to locate movable assets better, ease maintenance scheduling and assure maintenance performance, as well as help prevent loss. In applications such as warehousing and distribution, where containers and tugs need to be tracked, scheduled and maintained, workflow can be optimized by 20 percent or more and losses prevented, according to studies by Alinean.
  • Counterfeiting and Improve Security—In many industries, counterfeit or non-secure goods introduced into the supply chain cause large direct losses of revenue. RFID increases brand protection and helps mitigate safety, security, regulatory and liability risks. Improved tracking using RFID can identify and isolate issues more efficiently and effectively than manual bar-code scanning by introducing automated and more frequent checks and balances.
  • Accounts Receivable—With more accurate and real-time tracking of what has shipped, the accounts-receivable process can become much more efficient, with shorter billing and payment cycles. For example, RFID allows vendors to produce customer invoices automatically as soon as items are shipped. It also enables payment automation. This helps reduce the time to collect, while the improved accuracy and elimination of manual data entry or tracking errors helps reduce AR disputes. The results surveyed include a dramatic reduction in accounts receivable, down from 30 to 45 days to just minutes.
  • Market Mandates and Revenue Opportunities—Many industry leaders have set the stage by mandating RFID functionality and compliance in order to participate in their ecosystem. RFID can help meet these mandatory requirements, or provide an advantage for those who proactively implement the technology over those that are struggling to meet these new market demands. Longer-term, RFID can help create new revenue generating applications and innovation to help grow market share. In many cases, RFID is not just a business benefit, but a requirement for doing business.
  • Customer Experience—RFID can help to improve the overall customer experience. First, RFID enables better management of inventory; ensures proper deliveries and shipments; improves demand forecasts, promotions management and new product introductions; and reduces out-of-stock conditions. Elimination of supply-chain issues and product availability results in customers getting what they want, when they want it. In one case, a documented 29 percent increase in promotional execution resulted in a projected 20 to 60 percent increase in sales.
