How RFID Can Sharpen Your Business Intelligence
The former worldwide program director of RFID for Hewlett-Packard and Asia Pacific regional director for EPCglobal explains how the technology can be used to improve the quality of your business decisions.
Nov 28, 2011—The Ultimate Manufacturing Corp.'s VP of logistics put down the report and smiled. There had been considerable resistance two years prior, when he had engaged Smoke & Mirrors Logistics, but the company's performance report for the previous month showed it to be consistently exceeding the requirements of its service level agreement (SLA). In particular, its put-away performance had been outstanding, as it had been every month since the firm's launch. The SLA specified two hours from goods receipt to put away, and the task was always completed well within the requisite time—often within one hour. Such performance reports were provided for all of the company's operations, including manufacturing, materials management, line-side kanban replenishment and anywhere else that physical activity took place.
But what was that performance report based upon? Since what is being measured is a physical activity, the report could be based only upon observations of that activity. In the case of the requirements for put-away, that activity would consist of moving goods received from the inbound dock door to their correct storage location. The time taken to accomplish this is measured from when the products crossed the receiving dock door until the time at which they were put away. The SLA allows two hours for this task, so provided that all goods are put away within that timeframe, the SLA has been met.
It might not be. Imagine a scenario in which the logistics service provider (LSP) is short of warehouse associates, and thus risks not meeting the SLA. What if the truck were unloaded, and its contents temporarily staged at inbound, until sufficient labor was available to complete put-away, preferably in half the time specified in the SLA? That first scan is delayed until the LSP is sure that put-away can be completed well within the SLA's stipulations. No receiving scan is conducted, so the start time for the put-away measurement has not yet been triggered, even though the goods have been received.
The system would not record what had physically occurred. Consequently, the logical and physical inventory counts would be out of sync, and the LSP's reported performance would not match the actual physical performance achieved. Indeed, the reported performance would far exceed the actual levels. The LSP's customer would be happy, perhaps even extremely pleased, with the LSP's performance above and beyond SLA. But they would be happy about the performance that they did not receive, instead of being concerned about the one that they should have received but didn't.
So what can be done in these situations?
