Spacex, particularly in the development of Starship, is an example of the inappropriate use of an informal iterative project management and design approach. In other words it's a case of Agile, which is often the best kind of project management for software, infecting places where it shouldn't ought to go. In the end when you count up 33 rocket engines per iteration, it's going to end up being a lot more expensive than what more conventional projects like Blue Origin will cost.
