There is more: when a method requires you do steps A, B, C in order, you can do step A and then step C, and, when it is over, do step B (or just pretend that you have done it) because your boss told you to follow that step order or because you have to fulfil a norm that requires this method. With all the various methods there are now, you can invent infinite ways of getting around them. This is what is most rich and powerful about development methods :->
