DENSO’s solution worked because it joined physical delivery, ordering information, and ownership in one operating flow. ¹

DENSO connected the parts ordering system to AMR delivery, replacing manual conveyance and information flow. ¹ This enabled just-in-time delivery and reduced errors and delays. ¹ The comparison is therefore about operating design. The automated process created a consistent link from the need for parts to their movement toward production.

The solution also created an observable responsibility boundary. Warehouse and production teams gained clear ownership of delivery accuracy and timing. ¹ Continuous operation supported scale, with zero sick days recorded for the AMRs and over half a million successful missions by early 2023. ¹ The deployment then extended from initial warehouse use into line-side manufacturing. ¹

The broader lesson is to design automation around the decisions and handoffs that must remain visible, not only around the task being mechanised.

DENSO automated parts delivery with AMRs and increased accountability unexpectedly
