Right. They design the whole rocket, spend years to build the rocket exactly according to the design doc, then the rocket explodes on the launchpad and they have to start all over.
We recently saw waterfall versus agile in actual rockets
Blue Origin spent years meticulously designing their rocket. They tested it on the ground. On the first flight it got to orbit, but the first stage exploded while re-entering
SpaceX started building their rocket out of carbon fibre. Changed to stainless steel. Started flying subscale demos, flew high altitude full scale examples to find if their aerodynamics was right, and haven’t actually tried for orbit yet
Blue Origin is trying for a last generation rocket (where the first stage is recovered) but bigger, SpaceX is trying to create the next generation where both stages are recovered
The build phase took too much time, you now have 1 day to test all the features and design elements of the rocket, because launch day is tomorrow. Good luck!
These are all accurate, except the first Waterfall one, who also doesn’t go to Mars.

That’s why testing comes before launching.

So, we need waterfall testing to be separated?
