This report presents the application of the DMAIC methodology in a company in the e-commerce industry where it intended to solve a problem present in a fulfillment center affecting the outbound processes (packing and shipping of orders). A supportive process performed by a special machine, referred to as Tote Distributor, received containers called totes with picked items from the inventory storage and distributed them into the different lines installed for packing and shipping. The Tote Distributor was having high levels of recirculation percentage, which indicated the number of defects in the process; a defect being the result of an attempt to distribute a tote but for one or a series of reasons, the machine was not able to perform the task.
