“There are basically two approaches to building complex systems like rockets, linear and iterative design. The linear method begins with initial goal and moves through developing requirements to meet that goal, followed by numerous qualification tests of subsystems before assembling them into major pieces of the rocket, such as its structures, propulsion, and avionics. With linear design years are spent engineering a project before development begins. This is because it is difficult, time-consuming, and expensive to modify design and requirements after beginning to build hardware. The iterative approach begins with a goal and almost immediately leaps into concept designs, bench tests, and prototypes. This is the path that SpaceX chose. The mantra with this approach is build and test early, find failures, and adapt.”
