Does their cost/benefit analysis incorporate the cost of paying data scientists to build these models?<p>I'm really confused as to how the weight of a SKU is not information that's readily available to them from the manufacturer, or why a missing weight can't be determined as part of the fulfillment process. After all, you only need to weigh a SKU once, so it's only a problem the first time that item is packed. You'd think knowing the weights of products in your warehouse would be a solved problem by 3PLs and not one requiring the services of people with graduate degrees in statistics.
