Getting returns under control

Once returns handling becomes a systemized process, cycle times can be reduced from a week or much longer to less than a day.

By Jim Nelson, Accenture -- Modern Materials Handling, 6/1/2006

Returns can be ugly and often are. Too many DCs stack them in a corner, and process them only as a last resort or when staffing permits.

"I've seen as much as a 30-day backup in a returns area," says Jim Nelson, a partner in the supply chain management practice at Accenture.

As if that's not enough, returns often get overlooked in the capital expenditure process, too. But as Nelson explains, eventually the situation reaches a breaking point.

The drawing on this page details what that breaking point might look like. Returns are manually handled in a non-mechanized, paper-based data capture system. There is no software to manage the returns data. Depending on backlogs and physical log jams, the backup is at least a week, if not much longer. Excessive space is required for processing, manual tracking and inventory management. Merchandise is often damaged if not lost altogether. And needless to say, credits are tough to assess to customers.

  • No inbound scheduling
  • Paper documentation
  • Manual handling


 
Incremental Upgrade

Improvements

  • Shorter cycle times
  • Better use of space
  • Credits issued faster

While still mostly a manual operation, conveyors have been added to move and sort cases. Space utilization has been improved with the addition of conveyors as well as rack to organize the returned product. Bar codes now automatically capture data, allowing information to pass through the system more quickly and issuing credits sooner. There is still no capability to use advance ship notices to speed processing returns. As a result, inbound visibility is no better than before, affecting labor management. Backlog in the returns area has been reduced to 10 to 15 days, an important first step to gaining control of the process.

Improvements

  • Further reduction in cycle times
  • Still better use of space
  • Improved, but not optimized, labor use

A new information system holds the key here. A top-tier warehouse management system (WMS) now manages operations in the processing area. The WMS receives advance ship notices, providing inbound inventory visibility for labor and facility planning. Those notices also drive automated receiving and credit, speeds unloading in the processing area and updates to customer accounts. Meanwhile, the WMS directs inventory movement for maximum throughput and productivity as well as best use of space. Picking guided by the WMS is by wireless terminals and voice for faster movement of returns back to inventory and available to promise. Specific requirements for handling certain items can now be handled routinely.


Optimized System

Improvements

  • Shortest time of availability of inventory for new orders
  • Handling time reduced again
  • Best space and labor utilization

Now the WMS is fully integrated with the company's enterprise systems. That allows a direct connection from the advance ship notices to customer accounts as well as the company's ERP for efficient and dynamic inventory management. Incoming product is conveyed to inspection areas, processed according to pre-configured parameters originated by the enterprise resource planning (ERP) system and passed on to the WMS. As conveyors and other types of materials handling equipment move inventory through the area, data is immediately available to all key systems. Processes are dynamic with little opportunity for lost or damaged items. In the end, cycle time has been reduced to 12 to 48 hours, a far cry from the original week or more.
