Thomas Edison wasn't around for the Agile generation of today and yet he was a master of iteration. 9000 attempts before he created a working light bulb - no methodologies required. 🧠

Companies presenting the "fail fast" mentality often find themselves with teams who are jumping from failed project to failed project with no real value delivered to their customers.

SpaceX, who live by the fail fast rule have been incredibly successful. However, we cant discount Musks critical thinking and planning behind this. No doubt his well presented application of the fail fast mindset really means working iteratively on projects. 

Iteration is key, customer requirements are pivotal and we must test, measure and learn at every iteration of our process/product development to ensure success and avoid chaos.
