Like you said, it's all about having everything under one roof.

If you fab the PCBs yourself and pick and place the components yourself, you could make an electronics change in one day as long as you get the design right the first time and you had ordered the components in advance.

Changing the case shape would be harder to do fast, but could still happen in just 2-3 weeks if you have your tool-making and injection molding both in-house.

The reason anything takes longer for most companies is due to outsourcing, with all of its communications delays and shipping delays.
