Fellow robotics engineer here. Actually shipping things on time is hard. But giving the customer realistic expectations seems easier. If items are not shipping on time consistently, then providing some uncertainty in the delivery estimate would be nice. But of course, management probably feels like "2-4 day delivery" sounds bad so instead they project a false confidence in delivery date and then let the customer deal with the implications if delivery slips. This I feel is disrespectful to the customer.
