Thumpism, our shop does have checklist very similar to that. It is used as an accountability checklist, and I can almost do it from memory. Getting older now so I forget the exact order, but never forget a step!
Many of the higher level bikes have cartridge bearing hubs and headsets, and are not taken down and checked for grease. With through axle design it makes hub adjustment considerably easier or a non-entity. Headsets are much the same. Things have been simplified in many ways for the assembly crew, which allows consumer direct companies a leg up as assembly on their end is simplified and accurate.
Thanks goes out to Giant Bicycles for the "Ready to ride in 1/2 the time" initiative as it really has made a difference to retailers and the industry as aa whole.
