You need to have either an MES or an MES-lite system, depending on plant and product complexity, size and those kinds of things." ONE OF MANY EXAMPLES OF BENEFITS DTM benefits abound, but here's one from Hoeg. Some of Nexteer's electric steering systems consist of over 1,500 line items of performance data. Each of these steering systems is serialized with a radio frequency (RF) tag that acts as a license plate for that assembly. This serialization becomes the backbone of the digital information generated by manu- facturing, including machining data, maintenance, inventory control and MES. "You can keep only so much data on the RF tags," explains Hoeg, "so what we're doing is tracking pallets against serial numbers against performance data. Then we're using analytics from all of the performance data from the multiple test stands that these pallets flow through, and create a 'heat map.' The map helps us understand how to manage pallets, do maintenance repair and understand which pallets—actually, the assemblies on the pallets—are starting Nexteer manufacturing provides electric and hydraulic steering systems, steering columns, driveline systems, advanced driver assistance systems and automated driving technologies. 21
