This hits the fundamentals of lean and agile. Of course, the important thing to remember about innovation management is that this needs to be a progressive framework. Holding these various scales in balance during an innovation process is critical. Sloppy mistakes will kill you, but so will seeking perfection before you are ready. Perfection is the enemy of the good and you need to work your way up from “dream” to “engineer for 100x“! If you start the other way around, your odds of success are nearly zero.
