Logistics is defined by The Council of Logistics Management as: The process of planning, implementing, and controlling the efficient, cost effective flow of raw materials, in-process inventory, finished goods and related information from the point of origin to the point of consumption for the purpose of conforming to customer requirements. Reverse logistics includes all of the activities that are mentioned in the definition above. The difference is that reverse logistics encompasses all of these activities as they operate in reverse.
Therefore, reverse logistics is: The process of planning, implementing, and controlling the efficient, cost effective flow of raw materials, in-process inventory, finished goods and related information from the point of consumption to the point of origin for the purpose of recapturing value or proper disposal. More precisely, reverse logistics is the process of moving goods from their typical final destination for the purpose of capturing value, or proper disposal. Remanufacturing and refurbishing activities also may be included in the definition of reverse logistics.
Reverse logistics is more than reusing containers and recycling packaging materials. Redesigning packaging to use less material, or reducing the energy and pollution from transportation are important activities, but they might be secondary to the real importance of overall reverse logistics.
Importance of Reverse Logistics
If no goods or materials are being sent "backward", the activity probably is not a reverse logistics activity. Reverse logistics also includes processing returned merchandise due to damage, seasonal inventory, restock, salvage, recalls, and excess inventory. It also includes recycling programs, hazardous material programs, obsolete equipment disposition, and asset recovery.
In the software industry, distributors are attempting to cut down retailer returns by implementing just-in-time delivery. However, retailers generally overestimate demand because there is not much incentive for them to forecast carefully. Software manufacturers want the product on the retailer shelves, and often agree to stuff the channel. The cost of a box of software is low compared to the price. In one extreme example, a software manufacturer contracted with a third party to destroy 50 million copies of one software product. While this particular manufacturer would have preferred to not produce an excess of 50 million, the company believes that it is better to guess higher than lower. Because of these kinds of practices, return rates in the software industry recently hovered around 20 percent.
Additionally, releasing more software titles forces returns, because the product life cycles of those titles are contracting. Because their risk is low, some retailers will accept software purchased elsewhere. Other retailers, such as Sears, are trying to reduce returns and improve inventory turnover by reexamining channel relationships. Some of these retailers have begun setting up 30-day return policies.
The retail industry, under great competitive pressure, has used return policies as a competitive weapon. The greater the pressure, the more innovative the solutions. Within the retail industry, it appears that necessity, indeed, is the mother of invention.
Grocery retailers were the first to begin to focus serious attention on the problem of returns and to develop reverse logistics innovations. Their profit margins are so slim that good return management is critical. Grocery retailers first developed innovations such as reclamation centers. Reclamation centers, in turn, led to the establishment of centralized return centers. Centralizing returns has led to significant benefits for most firms that have implemented them.
Over the last several years, retailers have consolidated. Now more than ever, large retail chains are the rule. These large retailers have more power in the supply chain than retailers did a few years ago. In general, the large retailers are much more powerful than the manufacturers. Few manufacturers can dictate policy to large retailers such as Wal-Mart or Kmart. If a manufacturer will not accept returns, it is unlikely that the large retailer will accept those terms easily. In some exceptional cases, retailers will make allowances for a manufacturer's products that they believe are not replaceable with similar products.
Returns reduce the profitability of retailers marginally more than manufacturers. Returns reduce the profitability of retailers by 4.3 percent. The average amount that returns reduce the profitability among manufacturers is slightly less, at 3.80 percent. Survey respondents were asked how they disposition returns. On average, retailers use a centralized return facility to handle returns much more frequently than manufacturers. Retailers are also found to be more likely to sell returns to a broker or similar entity. They were less likely to remanufacture or refurbish than manufacturers which would seem logical given that manufacturers are better at manufacturing than retailers.
Manufacturers are significantly more likely to recycle or landfill returned material than retailers. It appears that retailers are further advanced than manufacturers when it comes to asset recovery programs. For other disposition options, such as resold as is, repackaging, or donation; retailer's responses were quite similar to manufacturers. In the table below, a comparison of disposition options between retailers and manufacturers is presented.
Disposition Options between Retailers and Manufacturers
|Sent to central processing facility||29.2%||17.7%|
|Resold as is||21.4%||23.5%|
|Repackaged and sold as new||20.5%||20.0%|
|Sold to broker||16.8%||10.1%|
|Sold at outlet Store||14.5%||12.8%|
It is clear both from the interviews and the survey instrument that retailers have made larger investments in technology to improve their reverse logistics systems. In fact, manufacturers lag behind retailers in almost every technology category. This difference between manufacturers and retailers does not appear to exist in all facets of an operation.
Nearly twice as many retailers as manufacturers included in the research implemented automated material handling equipment. Retailers are also more likely to use bar codes, computerized return tracking, computerized returns entry, electronic data interchange (EDI), and radio frequency (RF) technology to enhance their reverse logistics management. A comparison of reverse logistics technology adoption is presented below:
Comparison of Technologies Utilized to Assist Reverse Logistics Processing by Retail and Manufacturing Segments
|Automated material handling Equipment||31.1%||16.1%|
|Computerized return tracking||60.0%||40.2%|
|Computerized returns entry at most downstream point in supply chain||32.2%||19.1%|
|Electronic data interchange (EDI)||31.1%||29.2%|
|Radio frequency (RF)||36.7%||24.6%|
Reverse logistics practices vary based on industry and channel position. Industries where returns are a larger portion of operational cost tend to have better reverse logistics systems and processes in place. In the book industry, where great change in the industry structure has occurred in the last few years, returns are a major determinant of profitability. In the computer industry where life cycles are nearly as short as grocery life cycles, the speedy handling and disposition of returns is now recognized as a critical strategic variable.
Successful retailers understand that managing reverse logistics effectively will have a positive impact on their bottom line. Industries that have not had to spend much time and energy addressing return issues are now trying to make major improvements. Now, more than ever, reverse logistics is seen as being important.
In attempting to improve reverse logistics processes, a firm can move along several fronts. Suggested improvements are listed in the table:
|Streamline turn-in procedures
Route items with an eye to what happens to them next
Integrate the forward and reverse pipelines
|Explore the potential of commercial software applications or techniques for improving reverse flow management
Align financial incentives with improvements
Key Reverse Logistics Management Elements
Equip Your Warehouse with a Reverse Gear
It might be the most ignored aspect of warehouse operations today. But the need for efficient reverse logistics can not be brushed aside anymore. The return, processing, repair and replacement of products have a huge impact on customer service. And the nerve center of any such operation is the warehouse.
"One hundred percent of WMS packages were designed to get stuff out," says Bill Tyng, systems consultant with Forte Industries of Mason, Ohio. "They had to be adapted to get stuff back in." The situation has been more critical in Europe, where retailer policies tend to be more lax and returns can account for 30 percent of one's business. But reverse logistics is taking on increased importance in the U.S. as well. The trend has given rise to a number of niche vendors, offering software or services specifically to handle returns, while the larger integrated vendors are also scrambling to adjust.
"Reverse logistics can be the black hole of your warehouse," says Mary Haigis, chief marketing officer of Optum Inc. in White Plains, N.Y.,) The returns process involves huge inefficiencies, but they're manageable with the help of the right technology and processes. She cites a large retailer and customer of Optum that piloted a reverse-logistics application at a pair of its DCs through the Christmas season. "The company typically has a high rate of return," she says, "but realized 'incredible savings and efficiencies' with the help of a formal system."
